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…
Lieb-Schultz-Mattis Theorem in Open Quantum Systems
Kohei Kawabata, Ramanjit Sohal, Shinsei Ryu
The Lieb-Schultz-Mattis (LSM) theorem provides a general constraint on quantum many-body systems and plays a significant role in the Haldane gap phenomena and topological phases of…
Hermitian Bulk -- Non-Hermitian Boundary Correspondence
Frank Schindler, Kaiyuan Gu, Biao Lian +1
Non-Hermitian band theory distinguishes between line gaps and point gaps. While point gaps can give rise to intrinsic non-Hermitian band topology without Hermitian counterparts, li…
Symmetry classification of typical quantum entanglement
Yuhan Liu, Jonah Kudler-Flam, Kohei Kawabata
Entanglement entropy of typical quantum states, also known as the Page curve, plays an important role in quantum many-body systems and quantum gravity. However, little has hitherto…
Non-Hermitian boost deformation
Taozhi Guo, Kohei Kawabata, Ryota Nakai +1
The Hatano-Nelson model is one of the most prototypical non-Hermitian models that exhibit the intrinsic non-Hermitian topological phases and the concomitant skin effect. These phen…
