Antiferromagnetic skyrmion as a magnonic lens

Hongbin Wu (武宏斌), Zi-Wu Wang (王子武), and Jin Lan (兰金)

Phys. Rev. B 113, 174431 (2026) - Published 21 May, 2026

Spin-wave scattering in magnetic textures can be described as magnon deflection within a pseudomagnetic field. The authors disentangle here the individual contributions to spin-wave dynamics from the two sources of this field: the underlying magnetic topology and the Dzyaloshinskii-Moriya (DM) interaction. Their analysis shows that when the DM interaction prevails, the resulting pseudomagnetic field splits the magnon deflection into dual beams. This phenomenon turns an antiferromagnetic skyrmion into a built-in magnonic lens, capable of focusing and collimating spin waves.

Capturing long-range interactions with a reciprocal-space neural network

Ruijie Guo, Hongyu Yu, Liangliang Hong, Shiyou Chen, Xingao Gong, and Hongjun Xiang

Phys. Rev. B 113, 174101 (2026) - Published 4 May, 2026

Standard machine learning interatomic potentials often neglect crucial long-range interactions. Inspired by the Ewald summation method, the authors introduce here a reciprocal-space neural network to capture diverse long-range interactions (including Coulomb and van der Waals interactions), while preserving Euclidean symmetry. This approach significantly enhances the accuracy of the potentials and global properties for complex materials, such as defective gallium nitride and hafnium oxide.

Pereira, Bob Nagler, Dimitri Khaghani, Hae Ja Lee, Nicholas A. Czapla, Travis Volz, Ian K. OCampo, James McNaney, Thomas E. Lockard, Jon H. Eggert, Amy Lazicki, Christopher E. Wehrenberg, Andrew Krygier, and Raymond F. Smith

Phys. Rev. B 113, 174111 (2026) - Published 15 May, 2026

Here, the authors combine laser-driven shock compression, femtosecond x-ray diffraction, and machine-learned molecular dynamics to show that titanium exhibits an unexpectedly broad solid-liquid coexistence regime. They find first evidence of liquid near 86 GPa and residual textured β-Ti to ~180 GPa, while identifying key experimental artifacts that can obscure both melt onset and completion.

Spiral spin liquid resilient to quantization in the frustrated honeycomb antiferromagnet GdZnPO

Xun Chen, Rui Bian, Yuqian Zhao, Haijun Liao, Weiqiang Yu, Yi Cui, and Yuesheng Li

Phys. Rev. B 113, 174402 (2026) - Published 4 May, 2026

Spin liquids usually emerge in low-spin (S=½ or 1) systems with strong quantum fluctuations. Here, the authors show that GdZnPO—a structurally disorder-free, high-spin (S=7⁄2) frustrated honeycomb antiferromagnet—defies this expectation. Nuclear magnetic resonance (NMR) measurements reveal persistent spin dynamics and spin-liquid behavior down to the lowest accessible temperatures in GdZnPO.

3Q magnetic order with spatially alternating spin scalar chirality in overdoped Co0.336TaS2

Woonghee Cho, Pyeongjae Park, Chaebin Kim, Yeochan An, Kazuki Iida, Ryoichi Kajimoto, Sakib Matin, Romain Sibille, Scott A. Crooker, and Je-Geun Park

Phys. Rev. B 113, 174410 (2026) - Published 14 May, 2026

While underdoped Co1/3TaS2 shows a topological Hall effect, the overdoped Co0.336TaS2 variant does not. Traditionally, this was attributed to a simple helical spin order. However, using multimodal techniques—including inelastic neutron scattering and optical dichroism—the authors propose here a more complex triple-Q order. In this state, the spin scalar chirality alternates spatially, effectively cancelling the macroscopic Hall response. This study provides a new framework for detecting “hidden” multi-Q spin textures that standard transport measurements might miss.

Spin current generation via magnetic skyrmion, bimeron, and meron crystals

Aoi Kajihara, Shun Okumura, and Yukitoshi Motome

Phys. Rev. B 113, 174414 (2026) - Published 15 May, 2026

Efficient spin-current generation is a central challenge in spintronics. Here, the authors theoretically investigate electrically driven spin-current generation in two-dimensional metallic systems with different topological spin textures, including skyrmion, bimeron, and meron crystals. They demonstrate that each texture generates spin currents with characteristic spin-polarization directions. Remarkably, even a meron crystal with zero magnetization can generate a sizable spin current in the presence of spin–orbit coupling. Their results broaden the prospects for spintronics based on topological magnets.

Observation of Bethe strings in the quantum spin chain antiferromagnet BaCo2V2O8

Konrad Puzniak, A. T. M. Nazmul Islam, Xiaotong Chen, Jiahao Yang, Paul Steffens, Martin Boehm, Jianda Wu, and Bella Lake

Phys. Rev. B 113, 174419 (2026) - Published 18 May, 2026

Bethe strings, complex bound states of magnetic excitations, are a fundamental yet long-sought exotic states of 1D quantum Heisenberg magnets. Various string states are observed via inelastic neutron scattering measurements in the spin-chain compound BaCo2V2O8 in an applied longitudinal magnetic field. The experimental data exhibit quantitatively excellent agreement with theoretical predictions across a wide field range, providing unambiguous validation of Bethe string excitations. These results reveal the underlying spectrum, including at high energies, of spin chains in the quantum critical region.

Accessing dirty-regime anomalous Hall effect in pure ferromagnetic metals

Tengfei Ma, Lingsong Huang, Ning Jiang, Yaoxiang Jiang, Guixin He, Shifeng Zhao, Cong Wang, Wenyu Xing, and Weibo Gao

Phys. Rev. B 113, 174428 (2026) - Published 19 May, 2026

The anomalous Hall effect (AHE) in the dirty regime of pure ferromagnetic metals is challenging to access without doping. Here, the authors use cluster beam deposition to tune structural disorder in ferromagnetic nanogranular CoFe films, reaching a low- conductivity metallic state and enabling systematic study of the AHE in the dirty regime. The AHE is dominated by the intrinsic mechanism and follows the predicted scaling σAHE σxx1.6. This work fills a key experimental gap and establishes a disorder-based platform for engineering the AHE.

Complex temperature-dependent thermal conductivity in the sawtooth chain magnet Fe2SiSe4

Kunya Yang, Feihao Pan, Liran Wang, Chenglin Shang, Ying Zhu, Xiancai Hu, Sanjiang He, Xinrun Mi, Long Zhang, Aifeng Wang, Yisheng Chai, Frederic Hardy, Christoph Meingast, Peng Cheng, and Mingquan He

Phys. Rev. B 113, 174442 (2026) - Published 29 May, 2026

Here, the authors show that spin–phonon scattering can strongly tune phonon heat transport in the frustrated sawtooth-chain magnet Fe2SiSe4. Resonant scattering of phonons by magnetic excitations produces a broad thermal conductivity maximum in the single-q state, while this scattering is suppressed in the double-q state, yielding a fivefold-enhanced low-temperature peak. The results highlight frustrated magnets as prominent platforms for controlling thermal conductivity.

High-efficiency superconducting diode effect in a gate-tunable double-loop SQUID

Wyatt Gibbons, Teng Zhang, Kevin Barrow, Tyler Lindemann, Jukka I. Väyrynen, and Michael J. Manfra

Phys. Rev. B 113, 174505 (2026) - Published 13 May, 2026

The authors present here measurements of a double-loop superconducting quantum interference device (SQUID) with two gate-tunable hybrid InAs/Al Josephson junctions on each branch. This device enables controlled interferometry of three highly non-sinusoidal current-phase relationships (CPRs), revealing a significant superconducting diode effect. Through optimized gate and flux tuning, they achieve a device configuration where more than triple the supercurrent can flow in one direction compared to the other, and they accurately model this behavior with the expected CPR of the full device.

Inherent momentum-dependent gap structure of altermagnetic superconductors

Christian L. H. Rasmussen, Jannik Gondolf, Mats Barkman, Mercè Roig, Daniel F. Agterberg, Andreas Kreisel, and Brian M. Andersen

Phys. Rev. B 113, 174513 (2026) - Published 14 May, 2026

The authors study here superconductivity in altermagnetic metals using microscopic models, investigating the importance of the sublattice degree of freedom. They demonstrate that the sublattice polarization of the altermagnetic state imprints an anisotropic structure on the superconducting gap with nodes at the Brillouin zone boundary, despite arising from a momentum-independent bare interaction. In the limit of large spin-split bands, nonunitary equal-spin triplet superconductivity is favored by longer-range same-sublattice pairing.

Quantum-geometric helical superconductivity

Aaron Dunbrack, Pauli Virtanen, and Tero T. Heikkilä

Phys. Rev. B 113, 174525 (2026) - Published 21 May, 2026

In flat-band superconductors, the superfluid weight and other physical parameters are determined by the quantum geometry. Here, the authors extend this analysis to superconductors that break time-reversal symmetry, where new phenomenology such as the superconducting diode effect can arise. In particular, the Lifshitz invariant, which quantifies time-reversal symmetry breaking effects to leading order, can be related to the quantum metric in an extended space that encompasses both momentum space and parameter space. The method also extends to density wave states.

Bethe strings, complex bound states of magnetic excitations, are a fundamental yet long-sought exotic states of 1D quantum Heisenberg magnets. Various string states are observed via inelastic neutron scattering measurements in the spin-chain compound BaCo2V2O8 in an applied longitudinal magnetic field. The experimental data exhibit quantitatively excellent agreement with theoretical predictions across a wide field range, providing unambiguous validation of Bethe string excitations. These results reveal the underlying spectrum, including at high energies, of spin chains in the quantum critical region.

The anomalous Hall effect (AHE) in the dirty regime of pure ferromagnetic metals is challenging to access without doping. Here, the authors use cluster beam deposition to tune structural disorder in ferromagnetic nanogranular CoFe films, reaching a low- conductivity metallic state and enabling systematic study of the AHE in the dirty regime. The AHE is dominated by the intrinsic mechanism and follows the predicted scaling σAHE σxx1.6. This work fills a key experimental gap and establishes a disorder-based platform for engineering the AHE.

Phys. Rev. B 113, 174431 (2026) - Published 21 May, 2026

Spin-wave scattering in magnetic textures can be described as magnon deflection within a pseudomagnetic field. The authors disentangle here the individual contributions to spin-wave dynamics from the two sources of this field: the underlying magnetic topology and the Dzyaloshinskii-Moriya (DM) interaction. Their analysis shows that when the DM interaction prevails, the resulting pseudomagnetic field splits the magnon deflection into dual beams. This phenomenon turns an antiferromagnetic skyrmion into a built-in magnonic lens, capable of focusing and collimating spin waves.

Here, the authors show that spin–phonon scattering can strongly tune phonon heat transport in the frustrated sawtooth-chain magnet Fe2SiSe4. Resonant scattering of phonons by magnetic excitations produces a broad thermal conductivity maximum in the single-q state, while this scattering is suppressed in the double-q state, yielding a fivefold-enhanced low-temperature peak. The results highlight frustrated magnets as prominent platforms for controlling thermal conductivity.

The authors present here measurements of a double-loop superconducting quantum interference device (SQUID) with two gate-tunable hybrid InAs/Al Josephson junctions on each branch. This device enables controlled interferometry of three highly non-sinusoidal current-phase relationships (CPRs), revealing a significant superconducting diode effect. Through optimized gate and flux tuning, they achieve a device configuration where more than triple the supercurrent can flow in one direction compared to the other, and they accurately model this behavior with the expected CPR of the full device.

The authors study here superconductivity in altermagnetic metals using microscopic models, investigating the importance of the sublattice degree of freedom. They demonstrate that the sublattice polarization of the altermagnetic state imprints an anisotropic structure on the superconducting gap with nodes at the Brillouin zone boundary, despite arising from a momentum-independent bare interaction. In the limit of large spin-split bands, nonunitary equal-spin triplet superconductivity is favored by longer-range same-sublattice pairing.

In flat-band superconductors, the superfluid weight and other physical parameters are determined by the quantum geometry. Here, the authors extend this analysis to superconductors that break time-reversal symmetry, where new phenomenology such as the superconducting diode effect can arise. In particular, the Lifshitz invariant, which quantifies time-reversal symmetry breaking effects to leading order, can be related to the quantum metric in an extended space that encompasses both momentum space and parameter space. The method also extends to density wave states.

Ginzburg-Landau theory of Rashba superconductors: Concave upper critical field

Fedor V. Kusmartsev, Anna Kusmartseva, Jack C. M. Hughes, Fatemah H. Alkallas, Amira Ben Gouider Trabelsi, Qihong Chen, and Kui Jin

Phys. Rev. B 113, 179601 (2026) - Published 4 May, 2026

Broken inversion symmetry together with Rashba spin-orbit coupling fundamentally alters how superconductivity withstands applied magnetic fields. This work constructs a symmetry-respecting Ginzburg–Landau framework for Rashba superconductors and demonstrates that the upper critical field Hc2(T) exhibits a distinctly concave temperature dependence in contrast to the usual saturationlike behavior of conventional superconductors. Within this theory, the interplay between Rashba coupling and the effective mass of Cooper pairs is shown to control the superconducting phase boundary, yielding a compact analytic tool for interpreting and fitting unusually high critical fields in noncentrosymmetric systems. The approach further reveals that parity-mixed, multicomponent order parameters can host soft relative-phase modes with axionlike properties, thereby connecting the physics of the phase boundary to topological superconductivity, spintronics, axion dark matter, and the targeted design of future quantum materials.

Giant oscillator strength of weakly bound excitons: From Rashba's vision to modern quantum technologies

Michael W. Swift and Alexander L. Efros

Phys. Rev. B 113, 179603 (2026) - Published 6 May, 2026

Emmanuel Rashba’s pioneering theory of giant oscillator strength (GOS) has proven foundational to modern quantum photonics. When excitons are weakly confined, they coherently explore their entire localization volume. This yields oscillator strengths that scale as the ratio of the exciton localization volume (area) to the cube (square) of the exciton radius in three-dimensional (two-dimensional) systems, dramatically exceeding those of free excitons. GOS directly reduces radiative decay times by the same factor, enabling subnanosecond emission. Landmark experimental confirmation in CuCl nanocrystals demonstrated that size-dependent radiative decay times match Rashba’s predictions exactly. Now unified with the concept of single-photon superradiance, GOS underpins ultrafast light emission across quantum-confined systems, enabling advances in high-speed optical communications, LEDs, nanolasers, and quantum information processing.

Rashba's method of invariants

T. L. Linnik

Phys. Rev. B 113, 179604 (2026) - Published 13 May, 2026

Here, an overview is provided of the development of the invariant method in semiconductor physics, starting from the its origins and highlighting the role of Emmanuel I. Rashba in developing it. The author examines the application of the invariant method to construct an appropriate effective-mass Hamiltonian. The key effects of the spin-orbit interaction are discussed, including not only classical Rashba and Dresselhaus splitting but also a new kind of magnetic spin splitting which has been predicted and experimentally verified recently. It is demonstrated that the invariant method has become a universal tool in modern solid-state physics, widely applied not only to three-dimensional but also to two-dimensional crystals, including graphene, silicene, and transition metal dichalcogenide monolayers, all of which play an important role in modern spintronics.

Intersubband electric dipole spin resonance in transition metal dichalcogenide heterobilayers

K. K. Grigoryan and M. M. Glazov

Phys. Rev. B 113, 179605 (2026) - Published 20 May, 2026

E. I. Rashba predicted that an electric field can drive spin resonance—the electric dipole spin resonance (EDSR) effect which is extensively studied in conventional semiconductors. Here, the authors extend this concept to transition metal dichalcogenide heterobilayers. They demonstrate that the electric dipole inter-spin-subband transitions, symmetry-forbidden in monolayers, become allowed once two distinct layers are stacked. Through symmetry analysis and a microscopic spin-orbit mixing model, they derive selection rules for all six high-symmetry stackings and show that the EDSR rate exceeds that of magnetic-dipole transitions by orders of magnitude. The effect naturally gives rise to a Rashba-type Hamiltonian, opening a pathway for efficient THz control of spin and valley degrees of freedom.
