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…

Dynamics of a tight-binding ring threaded by time-periodic magnetic flux
W. H. Hu, Z. Song
We analytically study the effects of periodically alternating magnetic fields on the dynamics of a tight-binding ring. It is shown that an arbitrary quantum state can be frozen coh…
