The optical PT -symmetric and PT -antisymmetric characteristics are simultaneously investigated in the four-level atoms trapped in one-dimensional and two-dimensional optical lattices. The atoms with Gaussian-distributed density are driven into the closed-loop configuration by a standing wave field,...
