HIGHLIGHTED ARTICLES

EDITORS' SUGGESTION

Emergence of many-body chaos in the presence of quasiparticles

Sibaram Ruidas, Sthitadhi Roy, Subhro Bhattacharjee, and Roderich Moessner

Phys. Rev. B 114, 014306 (2026) - Published 10 July, 2026

How does a many-body system transition from near-integrable quasiparticle dynamics to full chaos? Here, the authors develop a theory to describe this generic crossover. By analyzing the spatiotemporal profile of many-body chaos in a classical Heisenberg chain initialised with a dilute density of defects in an otherwise ordered background, they reveal a cascade of light cones seeded by scattering between these defects and the chaos light cone. Their results demonstrate a distinct progression from short-time integrability through an intermediate “scarred” regime, culminating in an avalanche of scattering events that produces the standard signature of many-body chaos.

EDITORS' SUGGESTION

Magnetism and magnetoelastic effect in the two-dimensional van der Waals multiferroic ${CuCrP}_{2} S_{6}$

Jiasen Guo, Ryan P. Siebenaller, Michael A. Susner, Jiaqiang Yan, Zachary Morgan, and Feng Ye

Phys. Rev. B 114, 014401 (2026) - Published 1 July, 2026

The ordered moment direction in the van der Waals multiferroic CuCrP $_{2}$ S $_{6}$ remains unresolved despite growing research interest. Here, the authors have determined the ground-state magnetic structure using neutron diffraction, revealing that the ordered moments align along the crystallographic $b$ axis with weak spin anisotropy. Magnetic field measurements further uncover a magnetoelastic coupling. This work provides firm basis for future magnetoelectric study and $i n$ $s i t u$ diffraction of strain-tunable magnetism in this two-dimensional magnet.

EDITORS' SUGGESTION

Low-temperature spin dynamics and absence of magnetic order in layered $α − {RuI}_{3}$

Hank C. H. Wu, Benjamin M. Huddart, Francis L. Pratt, Danrui Ni, Robert J. Cava, and Stephen J. Blundell

Phys. Rev. B 114, 014411 (2026) - Published 10 July, 2026

Quantum spin liquids are long-sought for their elusive, never-frozen magnetic states. In layered $α$ -RuI $_{3}$ , magnetic Ru ions form a honeycomb network related to the Kitaev material $α$ -RuCl $_{3}$ , yet muon spin relaxation reveals a strikingly different low-temperature behaviour. The authors show here that the spins remain dynamically fluctuating down to 50 mK and find evidence for 2D spin diffusion, supporting the view that $α$ -RuI $_{3}$ is a promising candidate for hosting a quantum spin liquid state.

EDITORS' SUGGESTION

Switching characteristics of electrically connected stochastically actuated magnetic tunnel junction nanopillars

Dairong Chen, Ahmed Sidi El Valli, Jonathan Z. Sun, Flaviano Morone, Dries Sels, and Andrew D. Kent

Phys. Rev. B 114, 014426 (2026) - Published 29 July, 2026

Magnetic tunnel junctions driven by stochastic spin-transfer switching can be coupled through simple electrical circuits to realize tunable Ising-like interactions. A Markov-chain model predicts the collective behavior of coupled junctions from single-device measurements, providing a foundation for probabilistic spintronic hardware.

EDITORS' SUGGESTION

Superconducting states and intertwined orders in metallic altermagnets

Xuan Zou, Rafael M. Fernandes, and Eduardo Fradkin

Phys. Rev. B 114, 014504 (2026) - Published 6 July, 2026

Metallic altermagnets offer a new setting for unconventional superconductivity because their Fermi surfaces are spin split despite vanishing net magnetization. Here, the authors show that equal-spin multicomponent $p$ -wave pairing gives rise to multiple superconducting transitions and intertwined superconducting phases driven by subleading normal-state instabilities. They further demonstrate that fluctuations of competing electronic orders fundamentally reshape the superconducting state: nematic fluctuations stabilize nematic superconductivity, whereas spin loop-current fluctuations select chiral phases, revealing routes toward both nematic and topological superconductivity.

Rashba-driven insights into molecular excitons

Hao Li, Sergei Tretiak, and Vladimir Chernyak

Phys. Rev. B 114, 019601 (2026) - Published 1 July, 2026

Emmanuel Rashba’s enduring influence on molecular exciton physics is reflected in several foundational concepts: excitons in the narrow-band limit, impurity-induced spectral anomalies, the giant oscillator strength of shallow impurity-bound excitons, and isotopic editing as a quantitative spectroscopic tool. Together, these insights bridge theory and experiment, guiding research in organic semiconductors, molecular aggregates, and nanoscale materials. Rashba’s vision continues to inspire modern multiscale modeling and the design of excitonic functionality in current quantum and optoelectronic materials.

Dynamics of photoexcited exciton-phonon systems: Time-dependent theoretical approaches

Darius Abramavicius, Arunjyoti Baidya, Vytautas Bubilaitis, and Leonas Valkunas

Phys. Rev. B 114, 019602 (2026) - Published 6 July, 2026

When molecular aggregates absorb light, the resulting exciton is shaped by a local phonon bath, which causes fluctuation, dephasing, and can eventually trap the excitation. This exciton-phonon coupling leads to exciton-polaron formation, transforming the coherent excitonic motion into the incoherent polaronic behavior. Here, the authors compare complementary time-dependent descriptions of this process. In the Heisenberg representation, the mean-field approximation treats phonons as classical fluctuating fields, while the one-quantum approximation retains one-phonon-assisted correlations and captures phonon sidebands in optical spectra. In parallel, a time-dependent variational polaron approach follows relaxation and self-trapping in the excited-state manifold. Together, these methods clarify how excitons evolve, decohere, and become coupled to vibrations.

Electric dipole spin-flip resonances in semiconductors: A personal perspective

Bruce D. McCombe

Phys. Rev. B 114, 019603 (2026) - Published 17 July, 2026

Emmanuel Rashba is responsible for a body of theory that demonstrates the profound effects of spin-orbit interaction on charge carriers in semiconductors. This notably includes the discovery of important effects on confined carriers in the presence of structural inversion asymmetry. The present article describes, from a personal perspective, experimental discovery and studies of electric-field-excited spin-flip resonances in semiconductors motivated by these theoretical predictions. Initial experiments in 1960 focused on electric-dipole excited spin resonance (EDSR) and combined cyclotron plus spin resonance (in 1967). Recent experiments on quasi-two-dimensional electrons in the quantum Hall effect regime in an asymmetric quantum-well structure have revealed unusual multiline EDSR spectra attributed to effects of Rashba spin-orbit effective fields of electrons in quantum Hall edge channels.
