Description:
Author(s): Zhaoyang Zhang, Yiqi Zhang, Jiteng Sheng, Liu Yang, Mohammad-Ali Miri, Demetrios N. Christodoulides, Bing He, Yanpeng Zhang, and Min Xiao We experimentally demonstrate P T -symmetric optical lattices with periodical gain and loss profiles in a coherently prepared four-level N -type atomic system. By appropriately tuning the pertinent atomic parameters, the onset of P T -symmetry breaking is observed through measuring an abrupt phase-shift … [Phys. Rev.
