Non-Hermitian quantum walks uncover dynamical quantum phase transitions under self-normal and biorthogonal bases
Guangzhen Li, Luqi Yuan · Light Science & Applications · 2026
The differences in critical times and critical momenta between self-normal and biorthogonal dynamical quantum phase transitions are revealed. The theoretical analysis is experimentally validated through multiple quench processes using a one-dimensional discrete-time non-Hermitian quantum walks.
