Abstract
Symmetry breaking of solitons in a class of one-dimensional parity-time () symmetric complex potentials with cubic nonlinearity is reported. In generic -symmetric potentials, such symmetry breaking is forbidden. However, in a special class of -symmetric potentials , where is a real and even function and a real constant, symmetry breaking of solitons can occur. That is, a branch of non--symmetric solitons can bifurcate out from the base branch of -symmetric solitons when the base branch’s power reaches a certain threshold. At the bifurcation point, the base branch changes stability, and the bifurcated branch can be stable.
