dc.descriptionThe spontaneous spin polarization and bifurcation delay in two-component Bose-Einstein condensates coupled with Raman pulses are investigated. We find that the bifurcation and the spontaneous spin polarization depend not only on the system parameters, but also on the relative phase between two components. Through bifurcations, the system enters into the spontaneous spin polarization regime from the Rabi regime. We also find that bifurcation delay appears when the parameter is swept through the static bifurcation point. This bifurcation delay is responsible for metastability leading to hysteresis. The area enclosed in the hysteresis loop increases with the sweeping rate of the parameter.
