Nielsen-Ninomiya Theorem with Bulk Topology: Duality in Floquet and Non-Hermitian Systems
Takumi Bessho, Masatoshi Sato
The Nielsen-Ninomiya theorem is a fundamental theorem on the realization of chiral fermions in static lattice systems in high-energy and condensed matter physics. Here we extend th…

Topological Quantum Walk with Discrete Time-Glide Symmetry
Ken Mochizuki, Takumi Bessho, Masatoshi Sato +1
Discrete quantum walks are periodically driven systems with discrete time evolution. In contrast to ordinary Floquet systems, no microscopic Hamiltonian exists, and the one-period…
