Nonequilibrium dynamics of magnetic hopfions driven by spin-orbit torque

Shoya Kasai, Shun Okumura, and Yukitoshi Motome

Phys. Rev. B 113, 134445 (2026) - Published 29 April, 2026

Magnetic hopfions are three-dimensional topological spin textures labeled by the Hopf invariant $H$ , whose rich knot topology and spatial mobility offer potential for cutting-edge memory devices. Here, the authors investigate hopfion dynamics driven by spin-orbit torque. Notably, high- $H$ hopfions exhibit hierarchical splitting dynamics. For instance, an $H = 4$ hopfion becomes unstable and divides into two $H = 2$ , each of which subsequently splits into two $H = 1$ . These findings suggest that the spin-orbit torque provides an effective means of switching the hopfion knot topology.

Temperature and conductivity in shock compressed bridgmanite ${MgSiO}_{3}$ up to $2 TPa$

M. F. Huff, M. C. Marshall, L. E. Hansen, N. Ozaki, T. Suer, Z. Lin, D. N. Polsin, D. J. Erskine, F. Gonzalez-Cataldo, T. Sato, K. Katagiri, T. Okuchi, D. E. Fratanduono, T. Sano, M. Noda, T.

Phys. Rev. B 113, 134104 (2026) - Published 6 April, 2026

Bridgmanite (MgSiO $_{3}$ ) is a major mantle constituent of rocky planets. Here, experimental temperature and reflectivity measurements in shock-compressed bridgmanite constrain its electrical conductivity at conditions relevant to super-Earth interiors. Comparison with prior studies indicates conductivity rises at lower pressures and temperatures than many models assume, suggesting silicate mantles may contribute to magnetic field generation over a broader range of conditions than previously believed.

EDITORS' SUGGESTION

Origin of energy gaps in quasicrystalline potentials

Emmanuel Gottlob, David Gröters, and Ulrich Schneider

Phys. Rev. B 113, 134202 (2026) - Published 16 April, 2026

Here, the authors show that an eightfold optical quasicrystal supports true energy gaps, a longstanding open question because ordinary band theory does not apply to quasicrystals. Using an infinite-size configuration-space approach, they trace the main gaps to local resonances and predict the number of states below them, with large-scale numerical simulations in close agreement.

EDITORS' SUGGESTION

Quantifying electron-nuclear spin entanglement dynamics in central-spin systems using one-tangles

Isabela Gnasso, Khadija Sarguroh, Dorian Gangloff, Sophia E. Economou, and Edwin Barnes

Phys. Rev. B 113, 134301 (2026) - Published 2 April, 2026

Achieving a quantitative understanding of the many-body entanglement dynamics in central spin systems has been challenging. To overcome this challenge, the authors analytically calculate entanglement using a metric called the one-tangling power. They focus on the example of an InGaAs quantum dot to study electron-nuclear entanglement when spins are either freely evolving or subject to dynamical decoupling. They analytically and numerically pinpoint conditions that give rise to maximal entanglement between target subsets of spins that could potentially serve as quantum memories.

EDITORS' SUGGESTION

In situ straining of epitaxial freestanding ferroic films by a microelectromechanical device

Simone Finizio, Tim A. Butcher, Maria Cocconcelli, Elisabeth Müller, Lauren J. Riddiford, Jeffrey A. Brock, Chia-Chun Wei, Li-Shu Wang, Jan-Chi Yang, Shih-Wen Huang, Federico Maspero, Riccardo Bertacco, and Jörg Raabe

Phys. Rev. B 113, 134408 (2026) - Published 3 April, 2026

Mechanical strain is a powerful handle used to control the physical properties of ferroic materials. To investigate its effect at the nanoscale, the combination of a high-resolution imaging technique such as x-ray ptychography with the means to apply an $i n$ $s i t u$ mechanical strain is necessary. Here, the authors present a setup for the tailored application of $i n$ $s i t u$ mechanical strains to freestanding thin films with a microelectromechanical system actuator and a proof-of-concept experiment on a freestanding multiferroic BiFeO $_{3}$ lamella.

EDITORS' SUGGESTION

Spin-wave resonance in yttrium iron garnet stripe domains

Daniel Prestwood, Christopher E. A. Barker, Kilian D. Stenning, Charlie W. F. Freeman, Tianyi Wei, Takashi Kikkawa, Troy Dion, Daniel Stoeffler, Yves Henry, Matthieu Bailleul, Noora Naushad, William Griggs, Thomas Thomson, Murat Cubukcu, Jack C. Gartside, Eiji Saitoh, Will R. Branford, and Hidekazu Kurebayashi

Phys. Rev. B 113, 134410 (2026) - Published 7 April, 2026

By combining static and dynamic measurement techniques, the authors reveal here a rich set of resonant spin wave modes due to stripe domain formations in a YIG film. The authors show how the micromagnetic state of the film greatly impacts the resonant modes observed, and provide detailed analysis of both the static and dynamic behavior using micromagnetic simulations.

EDITORS' SUGGESTION

Revised crystal structure, disordered spin dynamics, and dichotomous magnetic excitations in a field-induced intermediate state of the honeycomb Kitaev magnet ${Na}_{2} {Co}_{2} {TeO}_{6}$

Suheon Lee, Poonam Yadav, Raju Kalaivanan, Xianghan Xu, Kapil Kumar, Matthias J. Gutmann, Christian Balz, J. Ross Stewart, Chennan Wang, Zurab Guguchia, Hubertus Luetkens, Sang-Wook Cheong, Raman Sankar, Kwang-Yong Choi, and Sungkyun Choi

Phys. Rev. B 113, 134411 (2026) - Published 6 April, 2026

Here, the authors report the dichotomous nature of magnetic excitations in a field-induced intermediate state of Na $_{2}$ Co $_{2}$ TeO $_{6}$ , a leading candidate for a Kitaev quantum spin liquid in 3 $d$ -based systems. Using inelastic neutron scattering and muon experiments, they observe low-energy magnons and high-energy spinons in high magnetic fields, along with disordered spin dynamics. A revised crystal structure reveals a triangular Na layer that can better stabilize the spin liquid state under magnetic fields.

EDITORS' SUGGESTION

Magnetoelastic properties in the high-temperature magnetic phase of the skyrmion compound ${GdRu}_{2} {Si}_{2}$

J. Sourd, D. A. Mayoh, G. Balakrishnan, M. Uhlarz, J. Wosnitza, and S. Zherlitsyn

Phys. Rev. B 113, 134416 (2026) - Published 9 April, 2026

The metallic skyrmion magnet GdRu $_{2}$ Si $_{2}$ exhibits a fascinating sequence of complex and topological spin textures. Here, the authors focus on the recently discovered high-temperature phase, denoted phase VI. Using ultrasound techniques, they map precise phase boundaries and reveal a strong dependence of phase VI on the field direction. They further present evidence of tetragonal symmetry breaking driven by the magnetic order parameter in this phase.

EDITORS' SUGGESTION

Random singlet physics in the exchange-disordered two-dimensional triangular material ${YbCu}_{1.14} {Se}_{2}$

Caitlin S. T. Kengle, S. M. Thomas, R. Movshovich, Shengzhi Zhang, Eun Sang Choi, Minseong Lee, P. F. S. Rosa, and A. O. Scheie

Phys. Rev. B 113, 134427 (2026) - Published 16 April, 2026

Disordered quantum spin liquid materials often display both quantum fluctuations and glass freezing at low temperatures, which are difficult to reconcile. The authors study here intrinsically disordered triangular YbCu $_{x}$ Se $_{2}$ and show bulk properties strikingly similar to other triangular quantum spin liquid candidate compounds, especially a sublinear specific heat versus temperature. A phenomenological random singlet model is able to reproduce this signature, suggesting possibly universal behavior for quantum spin liquids with randomness in their spin interactions.

Electrical readout of topological spin order in ultrathin insulators with small magnetization

Jing Li, Huilin Lai, Andrew H. Comstock, Aeron McConnell, Bharat Giri, Yu Yun, Tianhao Zhao, Xiao Wang, Yongseong Choi, Xuemei Cheng, Jian Shen, Zhigang Jiang, Dali Sun, Wenbin Wang, and Xiaoshan Xu

Phys. Rev. B 113, 134436 (2026) - Published 21 April, 2026

Here, the authors demonstrate that the interfacial topological Hall effect enables an electrical readout of topological spin order in insulating magnets with extremely small magnetization. In Pt/hexagonal LuFeO $_{3}$ heterostructures, the spin topology from noncoplanar canting is imprinted onto Pt via magnetic proximity, producing a large Hall response detectable down to the ultrathin limit of 1.5 unit cells. This approach provides a sensitive probe of otherwise inaccessible magnetic order in ultrathin insulating systems.

Phys. Rev. B 113, 134446 (2026) - Published 29 April, 2026

Low-energy muon spectroscopy is a unique and sensitive way to probe local magnetic fields in thin films. Amorphous oxide thin films are a significant limiting factor for superconducting qubit performance. Both amorphous tantalum and niobium pentoxides exhibit magnetism, likely originating from oxygen vacancies, but with fundamentally different behavior. Niobium pentoxide shows magnetically disordered, lossy fluctuations exceeding to the qubit operational frequency range, whereas tantalum pentoxide exhibits static magnetic order with local fields exceeding the critical field, pointing to different decoherence mechanisms.

Controlled manipulation of intermediate state in a type-I superconductor

Xin-Sheng Gao, Qun Wang, Ya-Xun He, Xing-Jian Liu, Jun-Han Zhang, Kang-Hong Yin, Jia-Ying Zhang, and Jun-Yi Ge

Phys. Rev. B 113, 134520 (2026) - Published 22 April, 2026

The competition between attractive and repulsive vortex-vortex interactions in type-I superconductors gives rise to complex flux patterns, whose topology and dynamics remain challenging to control. Here, the authors investigate the intermediate state of tantalum, revealing a reversible transition between flux stripe and flux grid configurations driven by alternating current. The authors achieve direct imaging and controllable manipulation of flux domains, providing a pathway for controlling nonequilibrium flux organization.

EDITORS' SUGGESTION

Topological object of chiral superfluid ${}^{3}{He − A}$ confined in a parallel plate geometry

Y. Ikegai, Y. Hino, B. Tang, Z. Xu, T. Takagi, and Y. Sasaki

Phys. Rev. B 113, 134528 (2026) - Published 29 April, 2026

Chiral superfluid $^{3}$ He confined in parallel plate geometry may contain topological objects such as chiral domain walls. The existence of those topological objects is mainly studied through spectroscopic measurement of nuclear magnetic resonance together with theoretical modeling of the texture. Here, the authors use magnetic resonance imaging to obtain real-space images of the topological objects. They identify various textures of the observed topological objects through spectroscopic and relaxometric magnetic resonance imaging. Real-time motion and pair annihilation of the domain walls is also studied.

Spin-deflection coupling in carbon nanotubes

Mark S. Rudner

Phys. Rev. B 113, 139601 (2026) - Published 13 April, 2026

Emmanuel Rashba was an innovator throughout his long and industrious career, which spanned seven decades from the 1950s to the 2010s. Here, the author reviews the physics of spin-deflection coupling and recounts the state of the field that led Rashba to propose this new form of spin-orbit coupling in 2010. Through this mechanism, electron spins in low-dimensional materials couple directly to local deflections, rather than to deformations as in previously studied spin-orbit coupling mechanisms. This feature yields stronger coupling of spin to lattice vibrations at long wavelengths, and was invoked to explain a pronounced maximum of the spin relaxation rate observed near a narrow avoided crossing in the spectrum of single electron carbon nanotube quantum dots.

Photocurrents induced by $k$ -linear terms in semiconductors and semimetals

M. M. Glazov and E. L. Ivchenko

Phys. Rev. B 113, 139602 (2026) - Published 15 April, 2026

The authors have developed a six-band k·p model of chiral (1, 1/2)-fermions in semimetals of the $T$ cubic point group symmetry. Here, the model is used to describe the electronic structure, optical absorption, and photocurrent in chiral multifold silicides like RhSi. The effective Hamiltonian incorporates spin-orbit coupling between the orbital momentum $L$ = 1 and spin 1/2 as well as the linear-in-wavevector Rashba term, which is essential for the circular photogalvanic effect. Parameterized using tight-binding calculations, the model accurately reproduces the low-energy band structure. The authors also compute the intersubband absorption spectrum and the circular photocurrent, demonstrating a quantized low-frequency response governed by a topological charge of four and revealing deviations from the universal value with increasing the light frequency.

Coherent spin precession in a Rashba two-dimensional electron system as an effect of special relativity

Mark Johnson

Phys. Rev. B 113, 139603 (2026) - Published 16 April, 2026

A current of spin polarized electrons is injected into a Rashba two-dimensional system at the source electrode. Carriers move with ballistic trajectories and weakly relativistic velocity along the channel and the spin orientation is detected at the drain. The carriers precess coherently under the influence of an electric field $E$ provided by a gate voltage. The precession is demonstrated in two ways. 1) Record the drain voltage as $E$ varies from zero to values resulting in precession more than a full wavelength. 2) Keep $E$ constant and record the drain voltage for multiple values of channel length L, concluding with L greater than $λ$ . This unique precession occurs because of a special relativistic transformation of E, providing a magnetic field $H^{*}$ .

Phys. Rev. B 113, 139604 (2026) - Published 20 April, 2026

Rashba spin–orbit coupling (SOC), introduced in seminal works by Emmanuel Rashba, plays a central role in engineered topological superconductivity. In this Perspective, the authors review how Rashba SOC enables the realization of low-dimensional topological superconductors supporting Majorana zero modes, the key building blocks for topological quantum computation. They highlight how tuning the Rashba SOC can enhance the topological gap, and survey material platforms and design strategies where Rashba SOC is leveraged to create and control topological superconducting phases.

Early years of Rashba's scientific career in Ukraine: Size effects and much more

V. N. Sokolov and V. A. Kochelap

Phys. Rev. B 113, 139605 (2026) - Published 20 April, 2026

An important part of Professor Emmanuel Rashba’s scientific activity belongs to the period from 1954 until 1966, when he lived in Kiev (Ukraine) and worked at the Theoretical Department (headed by Professor S. I. Pekar) of the Institute of Semiconductors, NAS of Ukraine. In addition to the well-known results obtained by him that are currently widely cited, regarding the symmetry of electron bands, spin states, and various associated effects, Rashba also investigated electron transport in semiconductors. These studies show that even then Rashba had a clear understanding that future development of electronics would be directly related to the miniaturization of semiconductor devices, where the influence of sample sizes and physical boundaries significantly affect their electrical properties. Here, the authors briefly review Rashba’s pioneering works on size effects with emphasis on their strong influence on further development of the physics and theory of this interesting and important research area. In particular, his early works on the formation of electron concentration domains with different valley indices in multivalley semiconductors anticipated the emergence of a new direction in electronics, currently called valleytronics and tightly related to spintronics and other booming fields of study.

Fundamental symmetries of topological insulator effective models

Wouter Beugeling, Ewelina M. Hankiewicz, and Laurens W. Molenkamp

Phys. Rev. B 113, 139606 (2026) - Published 27 April, 2026

Symmetries play a crucial role in band structure theory of semiconductor materials, including well-known topological insulators like HgTe. In heterostructure devices, the electrostatic potential from the gate electrode breaks structural inversion symmetry, i.e., the reflection symmetry between the top and bottom of the device. Here, the authors explore structural inversion symmetry breaking in two-dimensional effective models like the Bernevig-Hughes-Zhang model and the Dirac model for surface states in three-dimensional topological insulators. By means of dimensional reduction, these effective models inherit the symmetry properties from k·p theory in three dimensions. In the end, the extra terms induced by the electric field are similar to Rashba spin-orbit coupling.
