Dynamics of one-dimensional tight-binding models with arbitrary time-dependent external homogeneous fields
W. H. Hu, L. Jin, Z. Song
The exact propagators of two one-dimensional systems with time-dependent external fields are presented by following the path-integral method. It is shown that the Bloch acceleratio…

Probability-preserving evolution in a non-Hermitian two-band model
W. H. Hu, L. Jin, Y. Li +1
A non-Hermitian PT-symmetric system can have full real spectrum but does not ensure probability preserving time evolution, in contrast to that of a Hermitian system. We present a n…
