Phys. Rev. A 69, 033611 (2004) [6 pages]Phase-dependent spontaneous spin polarization and bifurcation delay in coupled two-component Bose-Einstein condensatesReceived 28 October 2003; published 23 March 2004 The spontaneous spin polarization and bifurcation delay in two-component Bose-Einstein condensates coupled with laser or∕and radio-frequency pulses are investigated. We find that the bifurcation and the spontaneous spin polarization are determined by both physical parameters and relative phase between two condensates. 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 a static bifurcation point. This bifurcation delay is responsible for metastability leading to hysteresis. © 2004 The American Physical Society URL:
