Universal hard-edge statistics of non-Hermitian random matrices
Zhenyu Xiao, Ryuichi Shindou, Kohei Kawabata
Random matrix theory is a powerful tool for understanding spectral correlations inherent in quantum chaotic systems. Despite diverse applications of non-Hermitian random matrix the…
Spin Space Groups: Full Classification and Applications
Zhenyu Xiao, Jianzhou Zhao, Yanqi Li +2
In this work, we exhaust all the spin-space symmetries, which fully characterize collinear, non-collinear, commensurate, and incommensurate spiral magnetism, and investigate enrich…
Singular-Value Statistics of Non-Hermitian Random Matrices and Open Quantum Systems
Kohei Kawabata, Zhenyu Xiao, Tomi Ohtsuki +1
The spectral statistics of non-Hermitian random matrices are of importance as a diagnostic tool for chaotic behavior in open quantum systems. Here, we investigate the statistical p…
Antiparticle of exciton in semimetals
Lingxian Kong, Ryuichi Shindou, Yeyang Zhang
An emergent quantized field enriches quantum many-body systems. We propose an antiparticle analog of the exciton in semimetals as an emergent collective mode in interacting electro…
Berry curvature for coupled waves of magnons and electromagnetic waves
Akihiro Okamoto, Ryuichi Shindou, Shuichi Murakami
In this paper, we introduce Berry curvature, topological Chern number and topological chiral edge mode, that emerge from a hybridization between magnon and electromagnetic wave in…
Helicoidal excitonic phase in an electron-hole double layer system
Ke Chen, Ryuichi Shindou
We propose helicoidal excitonic phase in a Coulomb-coupled two-dimensional electron-hole double layer (EHDL) system with relativistic spin-orbit interaction. Previously, it was dem…
