Author(s): E. E. Zubov, I. Fita, R. Puzniak, and A. Wisniewski

A model of nonequilibrium thermodynamics of erbium orthoferrite is presented. The quantum-mechanical effects in arbitrary magnetic fields, related both to the direction of a general quantization axis and an influence of anisotropic exchange interactions on the magnetic structure, spin-reorientation …

Ultrafast demagnetization of ${\mathrm{Co}}_{2}\mathrm{Mn}{\mathrm{Si}}_{1\text{–}x}{\mathrm{Al}}_{x}$ Heusler compounds using terahertz and infrared light
Wei Zhang, Thomas Blank, Charles Guillemard, Claudia de Melo, Stéphane Mangin, Alexey Kimel, Stéphane Andrieu, and Gregory Malinowski
Author(s): Wei Zhang, Thomas Blank, Charles Guillemard, Claudia de Melo, Stéphane Mangin, Alexey Kimel, Stéphane Andrieu, and Gregory Malinowski

We investigate the ultrafast demagnetization in ${\mathrm{Co}}_{2}\mathrm{Mn}{\mathrm{Si}}_{1\text{–}x}{\mathrm{Al}}_{x}$ quaternary Heusler compounds induced by terahertz (THz) and infrared (IR) pulses. Adjusting the alloy's composition allows us to tailor the spin polarization at the Fermi energy …

Impurity and dispersion effects on the linear magnetoresistance in the quantum limit
Shuai Li, Hai-Zhou Lu, and X. C. Xie
Author(s): Shuai Li, Hai-Zhou Lu, and X. C. Xie

Magnetoresistance, that is, the change of the resistance with the magnetic field, is usually a quadratic function of the field strength. A linear magnetoresistance usually reveals extraordinary properties of a system. In the quantum limit where only the lowest Landau band is occupied, a quantum line…

Spin-dependent high-order topological states and corner modes in a monolayer FeSe/GdClO heterostructure
Qing Wang, Rui Song, and Ning Hao
Author(s): Qing Wang, Rui Song, and Ning Hao

We propose that a spin-dependent second-order topological insulator can be realized in a monolayer FeSe/GdClO heterostructure, in which substrate GdClO helps to stabilize and enhance the antiferromagnetic order in FeSe. The second-order topological insulator is free from spin-orbit coupling and in-p…

Giant enhancement of exciton radiative lifetime by ferroelectric polarization: The case of monolayer ${\mathrm{TiOCl}}_{2}$
Hongwei Qu and Yuanchang Li
Author(s): Hongwei Qu and Yuanchang Li

Exciton binding energy and lifetime are the two most important parameters controlling exciton dynamics, and the general consensus is that the larger the former, the larger the latter. However, our first-principles study of monolayer ferroelectric ${\mathrm{TiOCl}}_{2}$ shows that this is not always …

Second-order topological insulators and tunable topological phase transitions in honeycomb ferromagnets
Linke Cai, Runhan Li, Xinming Wu, Baibiao Huang, Ying Dai, and Chengwang Niu
Author(s): Linke Cai, Runhan Li, Xinming Wu, Baibiao Huang, Ying Dai, and Chengwang Niu

Intrinsic magnetic topological insulators categorized by bulk-boundary correspondence are of significant fundamental and technological importance in topotronics. Yet the topological phase transition with variation of the bulk-boundary correspondence remains elusive. Here, using a tight-binding model…

Two-dimensional isometric tensor networks on an infinite strip
Yantao Wu, Sajant Anand, Sheng-Hsuan Lin, Frank Pollmann, and Michael P. Zaletel
Author(s): Yantao Wu, Sajant Anand, Sheng-Hsuan Lin, Frank Pollmann, and Michael P. Zaletel

The exact contraction of a generic two-dimensional (2D) tensor network state (TNS) is known to be exponentially hard, making simulation of 2D systems difficult. The recently introduced class of isometric TNS (isoTNS) represents a subset of TNS that allows for efficient simulation of such systems on …

Magnetization dynamics and Peierls instability in topological Josephson structures
Adrian Reich, Erez Berg, Jörg Schmalian, and Alexander Shnirman
Author(s): Adrian Reich, Erez Berg, Jörg Schmalian, and Alexander Shnirman

We study a long topological Josephson junction with a ferromagnetic strip between two superconductors. The low-energy theory exhibits a nonlocal in time and space interaction between chiral Majorana fermions, mediated by the magnonic excitations in the ferromagnet. While short-ranged interactions tu…

Operator Relaxation and the Optimal Depth of Classical Shadows
Matteo Ippoliti, Yaodong Li, Tibor Rakovszky, and Vedika Khemani
Author(s): Matteo Ippoliti, Yaodong Li, Tibor Rakovszky, and Vedika Khemani

Classical shadows are a powerful method for learning many properties of quantum states in a sample-efficient manner, by making use of randomized measurements. Here we study the sample complexity of learning the expectation value of Pauli operators via “shallow shadows,” a recently proposed version o…

Experimental evidence for the existence of three-dimensional Dirac fermions in Au2Pb confirms a theoretically predicted Dirac semimetal phase with a fourfold degenerate Dirac crossing protected by rotational lattice symmetry.

Hydrogenic spin-valley states of the bromine donor in 2H-MoTe2
Hervé Aubin

Communications Physics, Published online: 09 June 2023; doi:10.1038/s42005-023-01244-7

Doping 2D materials is an effective way to engineer a wide range of properties of interest from catalysis to quantum bits. Here, the authors investigate Br-doped 2H-MoTe2 using electron spin resonance and scanning tunneling spectroscopy, demonstrating that the dopant-orbitals hybridise to the Q-valleys of the conduction band and produce long-lived spin states protected by spin-valley locking.

Kramers nodal lines and Weyl fermions in SmAlSi
Ming Yi

Communications Physics, Published online: 09 June 2023; doi:10.1038/s42005-023-01257-2

Kramers Nodal Lines (KNLs) have been theoretically proposed as special Weyl line degeneracies connecting time-reversal invariant momenta, but their observation in quantum materials is not established. Combining ARPES experiments with DFT calculations, the authors identify SmAlSi and its isostructural family as viable materials to host KNLs.
