Extracting Boundary Conformal Data from Periodic Non-Hermitian Critical Chains
Yifan Liu, Haruki Shimizu, Dongchang Liu +1
Boundary conformal field theory (BCFT) contains universal data that are usually accessed microscopically by imposing spatial boundaries on the lattice. In non-Hermitian many-body s…
Quantum geometry of the non-Hermitian skin effect
Ken-Ichiro Imura, Kohei Kawabata
The non-Hermitian skin effect is nonreciprocity-induced localization phenomena in which a macroscopic number of eigenstates accumulate anomalously at the boundary, accompanied by t…
Introducing a Kondo-type interaction to the model of quantum walkers
Manami Yamagishi, Naomichi Hatano, Kohei Kawabata +4
We introduce a model of discrete-time quantum walkers interacting with a lozalized magnetic impurity. Each quantum walker interacts with an impurity, through which multiple quantum…
Non-Hermitian Disordered Systems
Kohei Kawabata, Shinsei Ryu
Non-Hermitian disordered systems have emerged as a central arena in modern physics, with ramifications spanning condensed matter, quantum, statistical, and high energy contexts. Th…
