Topological band engineering and tunable thermal Hall effect in trimerized Lieb lattice ferromagnets
Fengjun Zhuo (卓冯骏), Jian Kang, Zhenxiang Cheng, and Aurélien Manchon
Author(s): Fengjun Zhuo (卓冯骏), Jian Kang, Zhenxiang Cheng, and Aurélien Manchon

We theoretically study the topological properties of magnons and the relevant magnon thermal Hall effect in trimerized Lieb lattice ferromagnets in the presence of next-nearest-neighbor Dzyaloshinskii-Moriya interactions. By calculating the magnon band structures and their Chern numbers with the lin…

Engineering a non-Hermitian second-order topological insulator state in quasicrystals
Chakradhar Rangi, Ka-Ming Tam, and Juana Moreno
Author(s): Chakradhar Rangi, Ka-Ming Tam, and Juana Moreno

Non-Hermitian topological phases have gained immense attention due to their potential to unlock novel features beyond Hermitian bounds. $\mathcal{P}\mathcal{T}$-symmetric (parity time-reversal symmetric) non-Hermitian models have been studied extensively over the past decade. In recent years, the to…

Stability of a quantum skyrmion: Projective measurements and the quantum Zeno effect
Fabio Salvati, Mikhail I. Katsnelson, Andrey A. Bagrov, and Tom Westerhout
Author(s): Fabio Salvati, Mikhail I. Katsnelson, Andrey A. Bagrov, and Tom Westerhout

Magnetic skyrmions are vortexlike quasiparticles characterized by long lifetime and remarkable topological properties. That makes them a promising candidate for the role of information carriers in magnetic information storage and processing devices. Although considerable progress has been made in st…

Author(s): Runze Han, Jiazhou Chen, Mengyue Zhang, Jinze Gao, Yicheng Xiong, Yue Pan, and Tianxing Ma

Here, the magnetic susceptibility of a triangular-graphene-quantum-dot-like system was examined by using the determinant quantum Monte Carlo method. We focused on three zigzag edge quantum dots or rings, namely, the triangular graphene quantum ring, bilayer triangular graphene quantum dots, and bila…

Topological states and flat bands on the maple leaf lattice
Ai-Lei He, Xu-Hui Yan, Lu Qi, Yongjun Liu, and Ying Han
Author(s): Ai-Lei He, Xu-Hui Yan, Lu Qi, Yongjun Liu, and Ying Han

Models with topological flat bands (TFBs) have been proposed on which the fractional Chern insulators (FCIs) have been studied. To flatten the lowest energy band, some long-range hopping terms are considered in Chern insulator (CI) models. In this paper, we study a tight-binding model on a maple lea…

Spin-valley locking in Kekulé-distorted graphene with Dirac-Rashba interactions
David A. Ruiz-Tijerina, Jesús Arturo Sánchez-Sánchez, Ramon Carrillo-Bastos, Santiago Galván y García, and Francisco Mireles
Author(s): David A. Ruiz-Tijerina, Jesús Arturo Sánchez-Sánchez, Ramon Carrillo-Bastos, Santiago Galván y García, and Francisco Mireles

The joint effects of Kekulé lattice distortions and Rashba-type spin-orbit coupling on the electronic properties of graphene are explored. We modeled the position dependence of the Rashba energy term in a manner that allows its seamless integration into the scheme introduced by Gamayun et al. [New J…

General corner charge formulas in various tetrahedral and cubic space groups
Hidetoshi Wada, Katsuaki Naito, Seishiro Ono, Ken Shiozaki, and Shuichi Murakami
Author(s): Hidetoshi Wada, Katsuaki Naito, Seishiro Ono, Ken Shiozaki, and Shuichi Murakami

In some insulators, corner charges are fractionally quantized, due to the topological invariant called a filling anomaly. The previous theories of fractional corner charges have been mostly limited to two-dimensional systems. In three dimensions, only limited cases have been studied. In this study, …

The new JWST observatory is revealing far more bright galaxies in the early Universe than anyone predicted, and astrophysicists have more than one explanation for the puzzle.

Author(s): Yeyang Sun, Xiangrui Hou, Tuo Wan, Fangyu Wang, Shiyao Zhu, Zhichao Ruan, and Zhaoju Yang

Non-Hermitian skin effect and photonic topological edge states are of great interest in non-Hermitian physics and optics. However, the interplay between them is largely unexplored. Here, we propose and demonstrate experimentally the non-Hermitian skin effect constructed from the nonreciprocal flow o…

Self-Organized Evolution of the Internal Transport Barrier in Ion-Temperature-Gradient Driven Gyrokinetic Turbulence
Shaojie Wang, Zihao Wang, and Tiannan Wu
Author(s): Shaojie Wang, Zihao Wang, and Tiannan Wu

Understanding the self-organization of the most promising internal transport barrier in fusion plasmas needs a long-time nonlinear gyrokinetic global simulation. The neighboring equilibrium update method is proposed, which solves the secularity problem in a perturbative simulation and speeds up the …

A comprehensive theoretical study of octupolar quantum spin ice shows that the dynamical spin structure factor is characterized by a broad continuum with three distinctive peaks which could be confirmed with inelastic neutron scattering measurements.

Author(s): Feifei Xin, Ludovica Falsi, Yehonatan Gelkop, Davide Pierangeli, Guoquan Zhang, Fang Bo, Fabrizio Fusella, Aharon J. Agranat, and Eugenio DelRe

We experimentally and theoretically investigate thermal domain evolution in near-transition KTN:Li. Results allow us to establish how polarization supercrystals form, a hidden 3D topological phase composed of hypervortex defects. These are the result of six converging polarization vortices, each ass…

Author(s): Ruobing Mei, Yi-Fan Zhao, Chong Wang, Yafei Ren, Di Xiao, Cui-Zu Chang, and Chao-Xing Liu

We propose an intrinsic mechanism to understand the even-odd effect, namely, opposite signs of anomalous Hall resistance and different shapes of hysteresis loops for even and odd septuple layers (SLs), of MBE-grown ${\mathrm{MnBi}}_{2}{\mathrm{Te}}_{4}$ thin films with electron doping. The nonzero h…

Tantalum ditelluride (${\mathrm{TaTe}}_{2}$) belongs to the family of layered transition metal dichalcogenides but exhibits a unique structural phase transition at around 170 K that accompanies the rearrangement of the Ta atomic network from a “ribbon chain” to a “butterfly-like” pattern.
