摘要: Abstract In this paper, we theoretically study the spin dynamics of a spatially trapped Bose-Einstein condensate indirect excitons (IXs). A spontaneous parity-symmetry breaking bifurcation for bright is reported under non-resonant linearly polarized pumping. Above certain pumping amplitude, condensation spontaneously and stochastically adopts one two spin-polarized configurations Sz depending on initial occupations. This phenomenon bifurcations attributed to small energy splitting difference in dissipation rates between dark IX systems. The considered systems thus have potential applications memories, switches simulate interactions condensed lattices.
