Crystal fields and the properties of the Kitaev candidate ${Na}_{3} {Co}_{2} {SbO}_{6}$ probed with x-ray absorption spectroscopy

M. M. Ferreira-Carvalho, S. H. Chen, Y. C. Ku, S. Rößler, Robert Kluge, Ryan C. Morrow, Javier Herrero-Martín, P. Gargiani, C. Y. Kuo, C. F. Chang, Alexander C. Komarek, Z. Hu, M. W. Haverkort, and L. H. Tjeng

Phys. Rev. B 114, 175123 (2026) - Published 17 September, 2026

Here, the authors utilize high-precision inverse-partial-fluorescence-yield x-ray absorption and magnetic circular dichroism, together with full-multiplet cluster calculations, to probe the local electronic structure of the Kitaev candidate Na $_{3}$ Co $_{2}$ SbO $_{6}$ . The measurements reveal a dominant trigonal crystal field together with subtle deviations from trigonal symmetry. Accounting for this lower local symmetry enables a consistent description of both the spectroscopic data and the observed in-plane magnetization anisotropy, highlighting the importance of local distortions for Kitaev physics.

Disentangling bulk and surface electronic structure using targeted cleave planes in ${RuO}_{2}$

Maria H. Visscher, Sebastian Buchberger, Bruno Saika, Shu Mo, Lea Richter, Mats Leandersson, Craig Polley, Andrew P. Mackenzie, and Phil D. C. King

Phys. Rev. B 114, 175125 (2026) - Published 17 September, 2026

Using focused ion beam designed cleaving planes, the authors prepare different surface orientations of RuO $_{2}$ for study by angle-resolved photoemission spectroscopy. The high-resolution measurements this enables from two distinct surfaces, combined with electronic structure calculations, make it possible to better distinguish bulk versus surface states. In fact, they reveal that the ARPES spectra are largely dominated by surface, rather than bulk, states, and reveal how these are strongly impacted by spin-orbit coupling, surface stoichiometry, and structure.

LETTER

Ferroelectric switchable intrinsic nonlinear pure spin Hall current

Xingyu Yue, Xiaoliang Xiao, Jinyang Ni, Pei-Hao Fu, Wenqian Li, Jin-Zhu Zhao, Min-Quan He, Zhijun Jiang, Xin Wang, Rui-Qiang Wang, and Yuanjun Jin

Phys. Rev. B 114, L171108 (2026) - Published 14 September, 2026

Here, the authors propose a new concept of nonlinear pure spin current rooted in quantum geometry. A pure spin current carries electron spin sideways without a net charge current in the same direction, making it attractive for low-power devices. They predict a unique property that flipping the built-in electric polarization of a nonmagnetic material can reverse the pure spin current. This flipping behavior is absent in the conventional spin Hall effect, which has impeded potential applications of the spin Hall effect in spintronics for a long time. The systematic survey here identifies five crystal symmetry classes that allow this behavior, and quantum mechanical calculations predict it in five atomically thin ferroelectrics, paving the way for experimental detection and device application. The authors also propose an optical second-harmonic Kerr microscopy test with an estimated measurable signal, providing a practical route to verify electrically programmable, low-dissipation spin transport without magnetic order.

LETTER

High-order perturbation expansion of hydrodynamic phonon theory

Jordi Tur-Prats, Albert Beardo, Lluc Sendra, Almudena Diaz-Serrano, Brendan McBennett, Joshua L. Knobloch, Juan Camacho, and F. Xavier Alvarez

Phys. Rev. B 114, L171301 (2026) - Published 8 September, 2026

Far from equilibrium, heat flux profiles can exhibit complex and rapidly evolving shapes, hindering the formulation of macroscopic heat transport equations for energy currents in nanostructured semiconductors. Here, the authors address this challenge by decomposing the phonon distribution into a smooth component that captures its slowly evolving features and an arbitrarily complex component that accounts for higher-order corrections. Combined with the Boltzmann transport equation, this decomposition enables the prediction of heat transport under extreme confinement by modeling the slowly evolving component deterministically using the finite element method, while capturing the rapidly evolving component stochastically through a Monte Carlo scheme.

LETTER

Role of charge in thermodynamic uncertainty relations

David Christian Ohnmacht, Wolfgang Belzig, and Juan Carlos Cuevas

Phys. Rev. B 114, L171401 (2026) - Published 8 September, 2026

The authors demonstrate here that the charge value of transport mechanisms impacts the validity of thermodynamic uncertainty relations (TURs) in the context of quantum transport in nanoscale junctions. They show that the recently established quantum TUR can be violated by the presence of transport processes that carry more than one charge, like Andreev reflection processes. To adequately address thermodynamic constraints in systems containing higher-order charge transport mechanisms, the authors propose a modified quantum TUR suitable for noninteracting electronic transport.
