Fermi surface studies of altermagnetic CrSb from Shubnikov–de Haas oscillations

Sajal Naduvile Thadathil, Beat Valentin Schwarze, Jaafar Ansari, Tommy Kotte, Sven Luther, Marc Uhlarz, Freya Husstedt, Rafael Gonzalez-Hernandez, Libor Šmejkal, Thanassis Speliotis, Markéta Žáčková, Jiří Pospíšil, Christoph Müller, Dominik Kriegner, Helena Reichlová, Jochen Wosnitza, and Toni Helm

Phys. Rev. B 114, 185104 (2026) - Published 3 September, 2026

The authors present here results from electrical magnetotransport measurements on microstructures of altermagnetic CrSb in pulsed fields up to 68 T. They study the temperature and field-orientation dependence of magnetic quantum oscillations in combination with first-principles calculations. The observed frequency spectrum agrees well with density functional theory calculations that take spin-orbit coupling into account, without invoking significant $a d$ $h o c$ band shifts. The findings validate the predicted electronic band structure of CrSb hosting multiple semimetallic bands and a locally alternating spin polarization.

EDITORS' SUGGESTION

Coexisting magnetic, charge, and superconducting orders in the two-dimensional Hubbard model

Robin Scholle, Pietro M. Bonetti, Walter Metzner, and Demetrio Vilardi

Phys. Rev. B 114, 185107 (2026) - Published 8 September, 2026

The authors analyze here the competition and coexistence of magnetic, charge, and $d$ -wave superconducting orders in the two-dimensional Hubbard model using renormalization-group-improved Hartree–Fock calculations. The resulting phase diagram reveals superconductivity coexisting with Néel order on the electron-doped side and with spiral or stripe order on the hole-doped side. In the stripe phase, the superconducting gap is spatially modulated together with the charge order.

Bridging the gap between numerics and experiment in freestanding graphene

Maksim Ulybyshev, Savvas Zafeiropoulos, Christopher Winterowd, and Fakher Assaad

Phys. Rev. B 114, 185110 (2026) - Published 8 September, 2026

Here, the authors revisit the question of the logarithmic renormalization of the Fermi velocity in graphene. Using large-scale Quantum Monte Carlo simulations of lattices with up to $2 \times 10^{4}$ interacting electrons, they directly connect experimental data with unbiased, nonperturbative calculations starting from a microscopic Hamiltonian. Their results reveal that even random-phase approximation corrections are quantitatively insufficient at realistic interaction strengths for suspended graphene, while continuum perturbation theory misses important lattice-scale effects. Remarkably, the optical conductivity still remains constant pointing to exact cancellation of different corrections.

Quadrupolar and dipolar phases of excitons in transition-metal dichalcogenide trilayer heterostructures

Michal Zimmerman, Daniel Podolsky, Ronen Rapaport, and Snir Gazit

Phys. Rev. B 114, 185116 (2026) - Published 15 September, 2026

In trilayer transition metal dichalcogenides, strong quantum fluctuations stabilize quadrupolar excitons. This study reveals how this state breaks down due to strong correlations at high exciton densities. Attractive interactions drive antiparallel dipolar correlations, explaining the redshift to blueshift transition observed in recent experiments. Furthermore, the authors predict novel correlation driven quantum phases, specifically an exciton droplet and a staggered dipolar crystal, and detail their distinct experimental signatures to guide future experimental explorations.

In search of diabolical critical points

Naren Manjunath and Dominic V. Else

Phys. Rev. B 114, 185119 (2026) - Published 15 September, 2026

We usually understand a critical point as occurring at a phase transition separating two distinct phases. Certain quantum many-body systems host unusual critical points that are entirely contained in a single phase of matter but are nonetheless protected for topological reasons. Here, the authors give general conditions when such “diabolical” critical points should exist and explore new types of classical phase transitions in which they might occur.

EDITORS' SUGGESTION

Class $C$ quantum network model with random tunneling and its nonlinear sigma model representation

D. S. Katkov, M. V. Parfenov, and I. S. Burmistrov

Phys. Rev. B 114, 185405 (2026) - Published 2 September, 2026

The spin quantum Hall effect is the superconducting counterpart of the integer quantum Hall effect. Here, the authors derive the long-distance nonlinear sigma model for a quantum network with random tunneling between chiral links carrying $N$ channels. Strong even–odd tunneling asymmetry breaks the saddle point down. Also, the triplet sector stays coupled to the singlet one and can turn anomalously soft. The longitudinal and spin Hall conductances can be tuned independently, giving a flexible platform for class- $C$ localization.

Kerr effect induced by exchange interaction of electrons separated by a tunnel barrier in a double quantum well

V. K. Kalevich, K. V. Kavokin, M. M. Afanasiev, B. F. Gribakin, M. I. Kuzmenko, G. Karczewski, and Yu. G. Kusrayev

Phys. Rev. B 114, 185412 (2026) - Published 9 September, 2026

Spin-spin interactions of itinerant charge carriers in semiconductors are weak and rarely accessible for quantitative measurement. Here, the authors detect electron spin precession in a wide quantum well in an in-plane magnetic field through the spin Kerr effect at the exciton resonance of a narrow tunnel-coupled quantum well. Through theoretical modeling, they show that this effect is due to interwell electron-electron exchange. The narrow well exciton exchange splitting of only tens of microelectronvolts is measured from the Kerr signal.

Extreme-ultraviolet optical response of atomically thin molybdenum disulfide

Giacomo Fiorentini, Nicola Di Palo, Giacomo Inzani, Gian Luca Dolso, Simone Bonetti, Qiuyang Li, Fang Liu, Xiaoyang Zhu, Angelo Giglia, Nicola Mahne, Luca Pasquali, Marco D'Alessandro, Mikhail Malakhov, María Camarasa-Gómez, Juan José Esteve-Paredes, Juan José Palacios, Rocío Borrego-Varillas, Mauro Nisoli, Antonio Picón, Davide Sangalli, and Matteo Lucchini

Phys. Rev. B 114, 185419 (2026) - Published 16 September, 2026

Here, the authors determine the extreme-ultraviolet optical constants of monolayer and bilayer MoS $_{2}$ through a combined experimental and first-principles study. They establish a consistent connection between two-dimensional conductivity and an effective three-dimensional refractive index, demonstrating that the optical response scales linearly with thickness. Unlike in the visible spectral range, they find that the XUV response is dominated by local-field effects, largely suppressing distinct excitonic signatures and providing benchmark data for future XUV and attosecond spectroscopies.
