Perfect State Transfer in PT-symmetric Non-Hermitian Networks
X. Z. Zhang, L. Jin, Z. Song
We systematically study the parity- and time-reversal (PT) symmetric non-Hermitian version of a quantum network proposed in the paper of Christandl et al. [Phys. Rev. Lett. 92, 187…

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…
