Beyond Gaussian fluctuations of quantum anharmonic nuclei

Antonio Siciliano, Lorenzo Monacelli, and Francesco Mauri

Phys. Rev. B 110, 134111 (2024) - Published 18 October, 2024

Gaussian fluctuations describe the quantum state of the nuclei, even in strongly anharmonic materials. However, this approximation fails spectacularly in molecular crystals with rotational motions and in tunneling modes. This paper presents a variational approach that overcomes these limitations through a nonlinear transformation of Cartesian coordinates. Employing Monte Carlo sampling of the quantum phase space at finite temperatures, the method maintains an analytical expression for the entropy, which ensures direct access to the free energy and, consequently, the phase diagram of materials.

Information scrambling and butterfly velocity in quantum spin glass chains

Venkata Lokesh K. Y., Surajit Bera, and Sumilan Banerjee

Phys. Rev. B 110, 134202 (2024) - Published 4 October, 2024

Information scrambling may become enhanced for systems with many metastable configurations, such as glasses, when the complex dynamics samples the multitude of configurations. The authors study here the scrambling in chains of quantum dots, modeled via two paradigmatic spin glass models – Sachdev-Ye and p-spin glass – and show that the butterfly velocity characterizing scrambling is enhanced above the glass transition where the dynamics is maximally complex. However, the evolution of glassy complexity with quantum and thermal fluctuations in the two spin glasses is very different.

Fading ergodicity

Maksymilian Kliczkowski, Rafał Świętek, Miroslav Hopjan, and Lev Vidmar

Phys. Rev. B 110, 134206 (2024) - Published 24 October, 2024

Here, the authors uncover a novel ergodic regime dubbed “fading ergodicity”. This is a regime in which a quantum system is still ergodic, however, it also acts as a precursor of the ergodicity breaking phase transition. In other words, “fading” ergodicity is a synonym of the “fading” colors of the leafs that are just about to fall off the tree. They conjecture this regime to be a generic property of quantum systems approaching the ergodicity breaking phase transition, and therefore, one cannot make a system nonergodic without first making the ergodicity fade.

Versatile braiding of non-Hermitian topological edge states

Bofeng Zhu, Qiang Wang, You Wang, Qi Jie Wang, and Y. D. Chong

Phys. Rev. B 110, 134317 (2024) - Published 22 October, 2024

The mathematical concept of braiding describes how string-like objects can be interwoven, including topologically distinct “links” and “knots”. A physical setting for realizing braids is the complex energy levels of non-Hermitian systems. The authors introduce here a route to generating energy braids, using topological edge states of non-Hermitian lattices. The model hosts braids like Solomon links and [n]-catenanes, which have not yet been observed physically. The model is experimentally feasible, requiring only a lattice with local gain and loss, without nonreciprocal coupling.

Room-temperature optomechanics with light-matter condensates

Vladislav Yu. Shishkov, Evgeny S. Andrianov, and Anton V. Zasedatelev

Phys. Rev. B 110, 134321 (2024) - Published 29 October, 2024

The authors develop here an optomechanical framework for macroscopic quantum states operational at room temperature — light-matter Bose-Einstein condensates with simultaneous strong exciton-photon and exciton-phonon interactions. Under resonant laser drive, they explore different polariton optomechanical scenarios that enable changing dissipative and dispersive properties of the system, assign vibrational states an effective mass, and open up new avenues to control polariton states by vibrations and vice versa.

Evidence of skyrmionic phase in a GdNi0.4Si1.6 single crystal

Gourav Dwari, Shovan Dan, Bishal Baran Maity, Ruta Kulkarni, and A. Thamizhavel

Phys. Rev. B 110, 134413 (2024) - Published 9 October, 2024

The topological Hall effect is often observed in materials that host the skyrmion lattice. Here, the authors present a comprehensive study of the magnetic phases observed in a GdNi0.4Si1.6 single crystal, which crystallizes in the centrosymmetric hexagonal crystal structure with the space group P6/mmm. The Hall data reveals the signature of topological Hall effect. A phase diagram constructed from the magnetic and transport studies highlights several magnetic phases, where a skyrmionic phase is sandwiched between these magnetic phases in a narrow field range.

Field-free switching of Tm3Fe5O12 on miscut garnet substrates with entangled spin Hall magnetoresistance and anomalous Hall resistance

Lin-Zhu Bi, Jintao Ke, Dalin Zhang, Guansong Li, Pengju Wang, Chaoqun Hu, Zhaozhao Zhu, Y. W. Liu, Ying Zhang, and J. W. Cai

Phys. Rev. B 110, 134415 (2024) - Published 9 October, 2024

The authors study here the structural, magnetic, and unique magnetotransport properties of Tm3Fe5O12/Pt heterostructures epitaxially grown on miscut Y3(Sc2Ga3)O12 substrates. The resulting deviation of magnetic easy axis from the film normal enables field-free current-induced switching. Remarkably, it also makes the anomalous Hall resistance entangled with the transverse effect of the spin Hall magnetoresistance under in-plane fields. The Hall resistance magnitude and polarity in monitoring the current-induced magnetization switching are thereby significantly modified when applying in-plane fields. The results are verified theoretically.

Gallery of soft modes: Theory and experiment at a ferromagnetic quantum phase transition

P. C. E. Stamp, D. M. Silevitch, M. Libersky, Ryan McKenzie, A. A. Geim, and T. F. Rosenbaum

Phys. Rev. B 110, 134420 (2024) - Published 11 October, 2024

Spectral divergences have long been important in physics, from the 19th century UV catastrophe to IR divergences in modern quantum field theory. In all these, “feedback” mechanisms quell the divergences. But what if multiple IR divergences – soft photons, phonons, and electronuclear magnons – conspire to produce finite decoherence at a quantum phase transition? The authors develop here the theory for these cancelling divergences and experimentally observe the resulting mode softening in a quantum Ising magnet, with implications from condensed matter to quantum gravity.

Signatures of fractionalization in the optical phonons of the hyperhoneycomb Kitaev magnet βLi2IrO3

Swetlana Swarup, Susmita Singh, and Natalia B. Perkins

Phys. Rev. B 110, 134421 (2024) - Published 11 October, 2024

The three-dimensional hyperhoneycomb Kitaev material β-Li2IrO3 has been proposed to host spin fractionalization. While its direct detection is challenging, the Fano shape of the Ag phonon observed in Raman spectra offers a promising clue. This study explains the Fano resonance as being consistent with the fractionalization of spins into Majorana fermions and ℤ2 fluxes, providing an indirect signature of the quantum spin liquid phase in β-Li2IrO3.

Detection of geometric phases in spin waves using nitrogen vacancy centers

Tomas T. Osterholt, Pieter M. Gunnink, and Rembert A. Duine

Phys. Rev. B 110, 134424 (2024) - Published 15 October, 2024

Spin wave geometric phases are well-known to play a fundamental role in magnon Hall effects and may ultimately be used to control spin waves in the field of magnonics. Here, the authors demonstrate theoretically how nitrogen-vacancy (NV) centers can be used to directly measure spin wave geometric phases in a variety of physical systems, including magnetic domain walls and magnetic rings with directional anisotropies.

Characterization of antiferromagnetic magnons using nitrogen vacancy center relaxometry

R. C. Heitzer, F. Pinto, E. Rodríguez, R. Rodríguez-Suárez, and J. R. Maze

Phys. Rev. B 110, 134431 (2024) - Published 21 October, 2024

Nitrogen vacancy (NV) centers in diamond are known for their capability of being optically manipulated. They can be coherently initialized in a specific spin state, and it is possible to measure their relaxation time. Here, the authors develop a theoretical description on how these relaxation rates are affected by the magnon (spin wave quanta) energies of different prototypical antiferromagnets, such as MnF2 and NiO. This information is useful to characterize magnetic parameters, such as the anisotropy or the effective exchange field.

Static and fluctuating zigzag order and possible signatures of Kitaev physics in torque measurements of αRuCl3

S. Froude-Powers, Subin Kim, Jacob Gordon, Hae-Young Kee, Young-June Kim, and S. R. Julian

Phys. Rev. B 110, 134439 (2024) - Published 23 October, 2024

The Kitaev spin liquid is a long-sought state of matter, for which α-RuCl3 has been a leading candidate since the observation of an apparently quantized thermal Hall effect at high magnetic field. In 2021, Gordon and Kee predicted a distinctive signature that must be present in the magnetic torque of such a Kitaev system. The authors of this paper report torque measurements that, after accounting for unexpected signals associated with magnetic order, do not show this predicted signature.

Majorana multipole response with magnetic point group symmetry

Yuki Yamazaki and Shingo Kobayashi

Phys. Rev. B 110, 134518 (2024) - Published 18 October, 2024

The identification of Cooper pair symmetry is a crucial initial step in the study of topological superconductors (TSCs). Here, the authors develop a theory for the identification of pairing symmetry in time reversal symmetry breaking TSCs, focusing on the electromagnetic responses of Majorana fermions at their surfaces. They explore how the pairing symmetries relate to the electromagnetic response of the Majorana fermions under magnetic point group symmetry. The study also predicts the appearance of a magnetic quadrupole response in odd-parity chiral superconductivity in UTe2 and ferromagnetic superconductivity in UCoGe.

Spectral divergences have long been important in physics, from the 19th century UV catastrophe to IR divergences in modern quantum field theory. In all these, “feedback” mechanisms quell the divergences. But what if multiple IR divergences – soft photons, phonons, and electronuclear magnons – conspire to produce finite decoherence at a quantum phase transition? The authors develop here the theory for these cancelling divergences and experimentally observe the resulting mode softening in a quantum Ising magnet, with implications from condensed matter to quantum gravity.

Signatures of fractionalization in the optical phonons of the hyperhoneycomb Kitaev magnet βLi2IrO3

Phys. Rev. B 110, 134421 (2024) - Published 11 October, 2024

The three-dimensional hyperhoneycomb Kitaev material β-Li2IrO3 has been proposed to host spin fractionalization. While its direct detection is challenging, the Fano shape of the Ag phonon observed in Raman spectra offers a promising clue. This study explains the Fano resonance as being consistent with the fractionalization of spins into Majorana fermions and ℤ2 fluxes, providing an indirect signature of the quantum spin liquid phase in β-Li2IrO3.

Spin wave geometric phases are well-known to play a fundamental role in magnon Hall effects and may ultimately be used to control spin waves in the field of magnonics. Here, the authors demonstrate theoretically how nitrogen-vacancy (NV) centers can be used to directly measure spin wave geometric phases in a variety of physical systems, including magnetic domain walls and magnetic rings with directional anisotropies.

Nitrogen vacancy (NV) centers in diamond are known for their capability of being optically manipulated. They can be coherently initialized in a specific spin state, and it is possible to measure their relaxation time. Here, the authors develop a theoretical description on how these relaxation rates are affected by the magnon (spin wave quanta) energies of different prototypical antiferromagnets, such as MnF2 and NiO. This information is useful to characterize magnetic parameters, such as the anisotropy or the effective exchange field.

The Kitaev spin liquid is a long-sought state of matter, for which α-RuCl3 has been a leading candidate since the observation of an apparently quantized thermal Hall effect at high magnetic field. In 2021, Gordon and Kee predicted a distinctive signature that must be present in the magnetic torque of such a Kitaev system. The authors of this paper report torque measurements that, after accounting for unexpected signals associated with magnetic order, do not show this predicted signature.

The identification of Cooper pair symmetry is a crucial initial step in the study of topological superconductors (TSCs). Here, the authors develop a theory for the identification of pairing symmetry in time reversal symmetry breaking TSCs, focusing on the electromagnetic responses of Majorana fermions at their surfaces. They explore how the pairing symmetries relate to the electromagnetic response of the Majorana fermions under magnetic point group symmetry. The study also predicts the appearance of a magnetic quadrupole response in odd-parity chiral superconductivity in UTe2 and ferromagnetic superconductivity in UCoGe.
