Description:
Author(s): X. Q. Li, X. Z. Zhang, G. Zhang, and Z. Song We study the possibility of asymmetric transmission induced by a non-Hermitian scattering center embedded in a one-dimensional waveguide, motivated by the aim of realizing quantum diodes in a non-Hermitian system. It is shown that a PT -symmetric non-Hermitian scattering center always has symmetric t... [Phys. Rev. A 91, 032101] Published Mon Mar 02, 2015
