We theoretically analyze the topological insulator (TI) surface state mediated interactions between local moments in a proximate 2D ferromagnetic insulator (FMI) motivated by recent experiments that show a significant increase in the Curie ...
A universal design principle for switchable control of the second-order nonlinear Hall effect [0.03%]

Manipulating the nonlinear Hall effect (NLHE) through non-volatile approach is of great significance for device applications, yet effective gating control remains elusive. In this Letter, using first-principles calculations and symmetry ana...
Jahn-Teller distortions induced strong negative thermal expansion in α-Cu2V2O7 [0.03%]

Negative thermal expansion (NTE) refers to volume contraction upon heating, but the intrinsic complexity of its physical mechanisms presents a fundamental challenge. α-Cu2V2O7 exhibits significant anisotropic NTE over a wider temperature r...
Anomalous statistics in the Langevin equation with fluctuating diffusivity: from Brownian yet non-Gaussian diffusion to anomalous diffusion and ergodicity breaking [0.03%]

Diffusive motion is a fundamental transport mechanism in physical and biological systems, governing dynamics across a wide range of scales---from molecular transport to animal foraging. In many complex systems, however, diffusion deviates f...

The possibility that evolutionary forces -- together with a few fundamental factors such as thermodynamic constraints, specific computational features enabling information processing, and ecological processes -- might constrain the logic of...

We demonstrate the existence of doubly charged exciton states in strongly screened bilayers of transition metal dichalcogenide (TMD) layers. These complexes are important because they are preformed electron pairs that can, in principle, und...
Orbital topology induced orbital Hall effect in two-dimensional insulators [0.03%]
二维绝缘体中轨道拓扑诱导的轨道霍尔效应

Yueh-Ting Yao et al.
Studies of ground-state topology in quantum materials have revealed the discovery of topological phases with novel Hall responses. Recently, the orbital Hall effect has drawn growing attention; however, the hidden origin behind large orbita...
Schwinger-Keldysh non-perturbative field theory of open quantum systems beyond the Markovian regime: Application to spin-boson and spin-chain-boson models [0.03%]
超越马尔可夫近似的开放量子系统非微扰场论：自洽哈密顿路径积分方法及自旋-声子和自旋链-声子模型应用

Felipe Reyes-Osorio et al.
We develop a unified framework for open quantum systems composed of many mutually interacting quantum spins, or any isomorphic systems like qubits and qudits, surrounded by one or more independent bosonic baths. Our framework, based on Schw...
