Transverse localization of light is investigated numerically in a serf-focusing Kerr medium with a complex-valued optical lattice featuring parity-time symmetry. It is demonstrated that the light localization exists b...
We investigate the behavior of two-dimensional (21)) atom localization in a three-level cascade-type atomic system via measuring the probe absorption. It is found that the precision of the atom localization can be ...
