The Witten Index for One-dimensional Non-unitary Quantum Walks with Gapless Time-evolution

Keisuke Asahara, Daiju Funakawa, Motoki Seki +1

Recent developments in the index theory of discrete-time quantum walks allow us to assign a certain well-defined supersymmetric index to a pair of a unitary time-evolution and…
