Anisotropic fine structure of ion tracks in single crystals

Jessica Wierbik, Hendrik Heimes, Christian Notthoff, Shankar Dutt, Taleb Alwadi, Alexander Kiy, Pablo Mota-Santiago, Nigel Kirby, and Patrick Kluth

Phys. Rev. B 113, 035306 (2026) - Published 20 January, 2026

Swift heavy ion irradiation of single crystals leaves permanent damage trails, ion tracks, that are commonly assumed to be cylindrical with circular cross-sections, a view shaped by the limited resolution of conventional characterization techniques. Using an advanced small-angle x-ray scattering method here, long-standing resolution limits are overcome and ion track cross-sections are probed with Angstrom-level precision. It is found that tracks in single crystals are not circular, but instead exhibit strong, orientation-dependent anisotropy, challenging the conventional assumption and revealing how crystal structure governs track formation.

Thermodynamic paradox and non-Hermitian topological singularities

Mário G. Silveirinha

Phys. Rev. B 113, 035103 (2026) - Published 2 January, 2026

Unidirectional lossless closed channels are fundamentally incompatible with thermal equilibrium. Challenging the widespread belief that dissipation alone restores thermodynamic consistency, this work shows that even dissipative nonreciprocal systems can exhibit unphysical thermal sinks and sources. A modal analysis reveals the competing roles of dissipative eigenmodes and their gain-conjugate partners, which together govern fluctuation-induced fields. Thermodynamic consistency is recovered only by accounting for nonlocality, revealing a deep connection between topology, bulk-edge correspondence, and equilibrium in passive systems.

Polarons and bipolarons in the Rydberg-dressed extended Bose-Hubbard model

G. A. Domínguez-Castro, L. Santos, and L. A. Peña Ardila

Phys. Rev. B 113, 035111 (2026) - Published 5 January, 2026

The authors explore here how a single and a pair of impurities behave across the superfluid and insulating (charge density wave) phases of a hard-core bosonic bath. In the superfluid regime, an impurity becomes a polaron-like quasiparticle, while in the insulating phase it regains its particle-like nature, moving through a potential landscape shaped by the charge density wave order. Furthermore, the authors show that two impurities can bind into a stable pair even without direct mutual interactions.

Symmetry-resolved magnetoelastoresistance in multivalley bismuth

Suguru Hosoi, Fumu Tachibana, Mai Sakaguchi, Kentaro Ishida, Masaaki Shimozawa, Koichi Izawa, Yuki Fuseya, Yuto Kinoshita, and Masashi Tokunaga

Phys. Rev. B 113, 035116 (2026) - Published 7 January, 2026

Here, the authors show that symmetry-resolved magnetoelastoresistance reveals two distinct mechanisms by which strain and magnetic fields shape electronic transport. The antisymmetric component captures the magnetic field response via field-modified mobility anisotropy, whereas the symmetric component remains nearly field independent. These findings establish a fundamental criterion for understanding magnetoelastoresistance and how strain and magnetic fields jointly govern electronic transport.

Kramers nodal line in the charge density wave state of YTe3 and the influence of twin domains

Shuvam Sarkar, Joydipto Bhattacharya, Pramod Bhakuni, Divya Jangra, Pampa Sadhukhan, Rajib Batabyal, Christos D. Malliakas, Marco Bianchi, Davide Curcio, Shubhankar Roy, Arnab Pariari, Sajal Barman, Mohammad Balal, Giovanni Di Santo, Luca Petaccia, Duck Young Chung, Yihao Wang, Vasant G. Sathe, Prabhat Mandal, Mercouri G. Kanatzidis, Philip Hofmann, Aparna Chakrabarti, and Sudipta Roy Barman

Phys. Rev. B 113, 035129 (2026) - Published 16 January, 2026

The authors demonstrate here that incommensurate charge density wave (CDW) driven inversion symmetry breaking in YTe3 produces a Kramers nodal line across the Brillouin zone. ARPES agrees well with ab initio band structure calculations when the CDW twin domains are considered. Consequently, symmetry-protected CDW shadow-band crossings with bilayer-split main bands that reach the Fermi level are identified. The noncentrosymmetric crystal structure has been established by x-ray crystallography and Raman spectroscopy. These findings establish YTe3 as a CDW-driven topological nodal-line metal.

Single crystal growth, structural and physical properties, and absence of a charge density wave in Ti0.85Fe6Ge6

Dechao Cheng, Nour Maraytta, Xiuhua Chen, Xizhi Li, Xueliang Wu, Xiangxiang Jing, Yong Hu, Youpin Gong, Mingquan He, Yisheng Chai, Xiaoyuan Zhou, Pengfei Jiang, Yilin Wang, Michael Merz, and Aifeng Wang

Phys. Rev. B 113, 035133 (2026) - Published 20 January, 2026

The rattling chain model predicts CDWs in AM6X6 kagome compounds with small filler atoms A embedded in a large M6X6 host. Here, despite Ti being a small filler atom, the authors observe no CDW in Ti0.85Fe6Ge6. Through in-depth electronic structure and bonding analyses, they demonstrate that, in addition to ionic radius, the bonding characteristics of the filler atom are crucial for CDW formation. This finding significantly extends the rattling chain model, offering new insights into the factors driving CDW transitions in kagome materials.

Symmetry-based real-space framework for realizing flat bands and discovering nodal-line touchings

Rui-Heng Liu and Xin Liu

Phys. Rev. B 113, 035140 (2026) - Published 21 January, 2026

The authors introduce here a systematic and unified real-space recipe to build flat bands from symmetric compact localized states. Multiple examples across different lattice symmetries, orbital contents and dimensions validate the versatility of the scheme. In addition, the authors derive concise criteria for determining all topological band crossings in flat-band systems — including intriguing nodal type — and demonstrate their intimate connection to underlying symmetries. The findings provide a generic theoretical framework for studying flat band models and materials.

Gapped boundaries of Kitaev's quantum double models: A lattice realization of anyon condensation from Lagrangian algebras

Mu Li, Xiao-Han Yang, and Xiao-Yu Dong

Phys. Rev. B 113, 035150 (2026) - Published 27 January, 2026

By establishing a direct correspondence between the axioms of Lagrangian algebras and consistency equations for boundary operators, the authors propose here a systematic framework for constructing all gapped boundaries of Kitaev’s quantum double models. This approach provides a microscopic characterization of bulk-to-boundary anyon condensation dynamics via the action of ribbon operators. Furthermore, the constructed lattice models naturally reproduce spontaneous symmetry-breaking patterns on the boundary, offering concrete realizations related to topological holography.

Slowly generated large nuclear field in bulk n-AlGaAs

A. Shen, J. Chen, R. Kaji, S. Yamamoto, H. Sasakura, T. Uemura, and S. Adachi

Phys. Rev. B 113, 035202 (2026) - Published 15 January, 2026

Here, the authors observe a large nuclear magnetic field, BN, exceeding 1 T in bulk n-AlGaAs via time-resolved Kerr rotation measurements, exhibiting a two-stage formation process comprising a rapid initial rise followed by gradual saturation. Based on experimental results, the authors modify the nuclear spin polarization formation model and conclude that a large BN forms due to the combined effects of increased electron localization sites from aluminum incorporation and the suppression of quadrupole-induced relaxation by a strong magnetic field.

Excitons in moiré superlattices with disordered electrons

Junghwan Kim, Dinh Van Tuan, and Hanan Dery

Phys. Rev. B 113, 035303 (2026) - Published 5 January, 2026

How do excitons probe electron crystals in moiré superlattices? The authors investigate here how the absorption amplitude and energy of excitons are influenced by charge order at fractional fillings of moiré superlattices. In addition to the sensitivity from s-p orbital mixing of excitonic states that stems from the charge order, this study also demonstrates how the moiré physics is suppressed by atomic defects and thermal fluctuations. This work provides a comprehensive picture that bridges theory and recent experimental observations.

Hyperfine interaction of electrons confined in CsPbI3 nanocrystals with nuclear spin fluctuations

Sergey R. Meliakov, Evgeny A. Zhukov, Vasilii V. Belykh, Kirill V. Kavokin, Mikhail O. Nestoklon, Evgeniya V. Kulebyakina, Mikhail L. Skorikov, Elena V. Kolobkova, Maria S. Kuznetsova, Manfred Bayer, and Dmitri R. Yakovlev

Phys. Rev. B 113, 035304 (2026) - Published 5 January, 2026

The authors measure coherent spin dynamics of electrons in CsPbI3 perovskite nanocrystals using time-resolved Faraday ellipticity. They find a finite Larmor precession frequency at zero magnetic field, corresponding to the electron spin splitting of 0.8 µeV induced by the hyperfine interaction of the electron with nuclear spin fluctuations. Using this experimental value and density functional calculations of the material band structure, the atomic hyperfine constant for the 5s orbital of iodine is evaluated as 190 µeV.

Spin-orbit coupling and the Edelstein effect at conducting ferroelectric domain walls

Maryam A. Nasir and W. A. Atkinson

Phys. Rev. B 113, 035425 (2026) - Published 15 January, 2026

Charged domain walls in ferroelectrics form conducting two-dimensional channels that can be manipulated by electric fields. They exhibit memristive behaviour that makes them, for example, candidate synapses in neuromorphic computers. Here, the authors show that for common domain-wall geometries, electrons are subject to nontrivial spin-orbit coupling. This result suggests that reconfigurable electronics with spin-orbitronic functionality may be possible.

Inelastic electron tunneling through adatoms and molecular nanomagnets

Daria Kývala and Jindřich Kolorenč

Phys. Rev. B 113, 035427 (2026) - Published 16 January, 2026

The authors discuss here a theory of the inelastic electron tunneling spectra of a magnetic nanosystem (an atom or a molecule) adsorbed on a solid surface measured in a scanning tunneling microscope. They study scenarios when the tunneling electrons sequentially interact with several magnetic centers or when the magnetic centers are made out of heavy atoms with a strong spin-orbit coupling. They discuss how the exchange interaction between the nanosystem and the tunneling electrons changes when orbital moments enter the picture.

Two-site Kitaev sweet spots evolving into topological islands

Rodrigo A. Dourado, J. Carlos Egues, and Poliana H. Penteado

Phys. Rev. B 113, 035432 (2026) - Published 21 January, 2026

Here, the authors demonstrate that Majorana bound states can be identified through a simple electrical transport measurement in artificial Kitaev chains composed of quantum dots coupled by superconductors. The key result is that the non-Abelian Majorana algebra – specifically the property γ2=½ – maps directly onto conductance. When this condition is met, the conductance locks to a robust half-quantized plateau e2/2h, signaling the emergence of “topological islands” with protected Majorana modes.

High-sensitivity photonic crystal biosensors using topological light trapping

Zhengzheng Zhai and Sajeev John

Phys. Rev. B 113, 035438 (2026) - Published 26 January, 2026

Photonic crystals (PCs) with localized optical cavity modes arising from topological domain wall line defects are simulated for optical biosensing. The authors demonstrate here a sensitivity almost 16 times higher than the previous designs, via a structure with thin silicon strips throughout the domain wall region. They analyze optical mode hybridization and its close relation to the transmission levels and correlations in frequency shifts of nearby optical resonances in response to analyte bindings. Three high-sensitivity chips are illustrated, all of which can distinguish three analyte bindings and their combinations completely in a single spectroscopic measurement.

Microscopic theory for electron-phonon coupling in twisted bilayer graphene

Ziyan Zhu and Thomas P. Devereaux

Phys. Rev. B 113, 035446 (2026) - Published 30 January, 2026

A quantitative microscopic description of electron-phonon coupling is a prerequisite for resolving the origin of superconductivity in twisted bilayer graphene. Here, the authors provide this fundamental component by developing a first-principles-based continuum theory for arbitrary twist angles. They report that coupling is strongly enhanced near the magic angle and persists up to 1.4° despite the loss of electronic flat bands. The study pinpoints specific phonon branches responsible and identifies a resonance between electronic bandwidth and phonon frequencies as the key condition for strong coupling.

Phys. Rev. B 113, 035202 (2026) - Published 15 January, 2026

Here, the authors observe a large nuclear magnetic field, BN, exceeding 1 T in bulk n-AlGaAs via time-resolved Kerr rotation measurements, exhibiting a two-stage formation process comprising a rapid initial rise followed by gradual saturation. Based on experimental results, the authors modify the nuclear spin polarization formation model and conclude that a large BN forms due to the combined effects of increased electron localization sites from aluminum incorporation and the suppression of quadrupole-induced relaxation by a strong magnetic field.

Phys. Rev. B 113, 035303 (2026) - Published 5 January, 2026

How do excitons probe electron crystals in moiré superlattices? The authors investigate here how the absorption amplitude and energy of excitons are influenced by charge order at fractional fillings of moiré superlattices. In addition to the sensitivity from s-p orbital mixing of excitonic states that stems from the charge order, this study also demonstrates how the moiré physics is suppressed by atomic defects and thermal fluctuations. This work provides a comprehensive picture that bridges theory and recent experimental observations.

The authors measure coherent spin dynamics of electrons in CsPbI3 perovskite nanocrystals using time-resolved Faraday ellipticity. They find a finite Larmor precession frequency at zero magnetic field, corresponding to the electron spin splitting of 0.8 µeV induced by the hyperfine interaction of the electron with nuclear spin fluctuations. Using this experimental value and density functional calculations of the material band structure, the atomic hyperfine constant for the 5s orbital of iodine is evaluated as 190 µeV.

Swift heavy ion irradiation of single crystals leaves permanent damage trails, ion tracks, that are commonly assumed to be cylindrical with circular cross-sections, a view shaped by the limited resolution of conventional characterization techniques. Using an advanced small-angle x-ray scattering method here, long-standing resolution limits are overcome and ion track cross-sections are probed with Angstrom-level precision. It is found that tracks in single crystals are not circular, but instead exhibit strong, orientation-dependent anisotropy, challenging the conventional assumption and revealing how crystal structure governs track formation.

Maryam A. Nasir and W. A. Atkinson

Phys. Rev. B 113, 035425 (2026) - Published 15 January, 2026

Charged domain walls in ferroelectrics form conducting two-dimensional channels that can be manipulated by electric fields. They exhibit memristive behaviour that makes them, for example, candidate synapses in neuromorphic computers. Here, the authors show that for common domain-wall geometries, electrons are subject to nontrivial spin-orbit coupling. This result suggests that reconfigurable electronics with spin-orbitronic functionality may be possible.

The authors discuss here a theory of the inelastic electron tunneling spectra of a magnetic nanosystem (an atom or a molecule) adsorbed on a solid surface measured in a scanning tunneling microscope. They study scenarios when the tunneling electrons sequentially interact with several magnetic centers or when the magnetic centers are made out of heavy atoms with a strong spin-orbit coupling. They discuss how the exchange interaction between the nanosystem and the tunneling electrons changes when orbital moments enter the picture.

Here, the authors demonstrate that Majorana bound states can be identified through a simple electrical transport measurement in artificial Kitaev chains composed of quantum dots coupled by superconductors. The key result is that the non-Abelian Majorana algebra – specifically the property γ2=½ – maps directly onto conductance. When this condition is met, the conductance locks to a robust half-quantized plateau e2/2h, signaling the emergence of “topological islands” with protected Majorana modes.

Photonic crystals (PCs) with localized optical cavity modes arising from topological domain wall line defects are simulated for optical biosensing. The authors demonstrate here a sensitivity almost 16 times higher than the previous designs, via a structure with thin silicon strips throughout the domain wall region. They analyze optical mode hybridization and its close relation to the transmission levels and correlations in frequency shifts of nearby optical resonances in response to analyte bindings. Three high-sensitivity chips are illustrated, all of which can distinguish three analyte bindings and their combinations completely in a single spectroscopic measurement.

Phys. Rev. B 113, 035446 (2026) - Published 30 January, 2026

A quantitative microscopic description of electron-phonon coupling is a prerequisite for resolving the origin of superconductivity in twisted bilayer graphene. Here, the authors provide this fundamental component by developing a first-principles-based continuum theory for arbitrary twist angles. They report that coupling is strongly enhanced near the magic angle and persists up to 1.4° despite the loss of electronic flat bands. The study pinpoints specific phonon branches responsible and identifies a resonance between electronic bandwidth and phonon frequencies as the key condition for strong coupling.
