EDITORS' SUGGESTION

Restoration of topological protection by adiabatic-geometry-induced suppression of intervalley mixing

Keita Funayama, Jotaro J. Nakane, and Ai Yamakage

Phys. Rev. B 114, 144103 (2026) - Published 9 September, 2026

Topological protection is weakened at armchair interfaces in quantum valley Hall systems because the two valleys mix and open a gap in the interface states. Here, the authors demonstrate that an adiabatic mass domain wall suppresses intervalley mixing, restoring robust propagation of topological interface modes throughout the bulk band gap. Experiments on silicon MEMS waveguides confirm efficient transmission through 90°, 120°, and 150° bends, establishing adiabatic geometry as a general strategy for designing versatile topological waveguides.

EDITORS' SUGGESTION

Magnetoelastic effects in the metallic frustrated antiferromagnet ${CrB}_{2}$

Tadataka Watanabe, Mai Watanabe, Sakurako Suganuma, Andreas Bauer, and Christian Pfleiderer

Phys. Rev. B 114, 144409 (2026) - Published 8 September, 2026

Here, the authors reveal contrasting magnetoelastic effects in the metallic frustrated magnet CrB $_{2}$ : softening associated with Fermi surface nesting in compressive modes and spin-Jahn-Teller fluctuations in the shear mode. These results highlight the distinct roles of longitudinal and transverse magnetoelastic couplings in frustrated metallic magnetism.

EDITORS' SUGGESTION

Odd-parity magnetism from the generalized Bloch theorem

Mikkel Christian Larsen and Thomas Olsen

Phys. Rev. B 114, 144414 (2026) - Published 14 September, 2026

Helimagnets naturally host odd-parity spin splitting — spin locked antisymmetrically to momentum — but their theoretical description is hindered by large, sometimes incommensurate magnetic supercells. Here, the authors show that the generalized Bloch theorem removes this barrier: bands, spin polarization, and wavefunctions of any single- $q$ helimagnet can be obtained in the primitive cell and downfolded in reciprocal space. From first principles for MnI $_{2}$ , NiI $_{2}$ , and MnTe $_{2}$ , the authors find splitting maximized for $p$ -orbital bands, and band spin texture that directly encodes the magnetic ordering vector.

LETTER

Metallic crossover through the tilt-free transition in ${La}_{3} {Ni}_{2} O_{7}$ at high pressure and temperature

Bastien Michon, Yingpeng Yu, Beatrice D'Alò, Elena Stellino, Gergely Németh, Bosen Wang, Jianping Sun, Jinguang Cheng, Paolo Postorino, Ferenc Borondics, and Francesco Capitani

Phys. Rev. B 114, L140102 (2026) - Published 1 September, 2026

Here, the authors map the temperature-pressure evolution of the bilayer nickelate La $_{3}$ Ni $_{2}$ O $_{7}$ and reveal that the suppression of tilts in oxygen octahedra is accompanied by a pronounced crossover toward a higher-carrier-density metallic state. By establishing the structural phase boundary over a broad temperature-pressure range, their results highlight the intimate interplay between lattice structure and electronic properties in this novel high-T $_{c}$ superconductor.

LETTER

Phase-resolved imaging of coherent phonon-magnon coupling

Yannik Kunz, Florian Kraft, David Breitbach, Kevin Künstle, Torben Pfeifer, Matthias Küß, Stephan Glamsch, Manfred Albrecht, and Mathias Weiler

Phys. Rev. B 114, L140403 (2026) - Published 9 September, 2026

The interaction between surface acoustic waves and spin waves may open new routes for compact and efficient passive microwave devices. The design of such devices requires understanding of the magnetoacoustic phenomena. Here, the authors use phase-resolved micro-optical imaging to detect and discriminate both types of waves in their micropatterned device. By tuning the magnetic field, the authors directly image the resonant magnetoacoustic coupling and provide experimental evidence for the coherent excitation of spin waves by the traveling acoustic wave.

Three-dimensional zigzag correlations in the van der Waals Kitaev magnet ${RuBr}_{3}$

H. Gretarsson, R. Iwazaki, F. Sato, H. Gotou, S. Francoual, J. Nasu, Y. Imai, K. Ohgushi, J. Chaloupka, B. Keimer, and H. Suzuki

Phys. Rev. B 114, L140404 (2026) - Published 10 September, 2026

Van der Waals materials can be exfoliated into ultrathin sheets, suggesting that their magnetism should also be two-dimensional. Using resonant x-ray scattering, the authors reveal here a different picture in the Kitaev magnet RuBr $_{3}$ : zigzag magnetic correlations exhibit spectral weight redistribution along the interlayer direction. Bromine’s spatially extended 4 $p$ orbitals strengthen interlayer magnetic interactions. The results demonstrate that an exfoliable crystal can host three-dimensional magnetism, challenging a common assumption about layered quantum materials and showing how ligand chemistry controls magnetic dimensionality.
