Phys. Rev. A 67, 053608 (2003) [5 pages]Symmetric-asymmetric transition in mixtures of Bose-Einstein condensatesReceived 6 November 2002; revised 31 January 2003; published 27 May 2003 We study a quantum phase transition in phase-separated mixtures of Bose-Einstein condensates. In this transition, the distribution of the two components changes from a symmetric to an asymmetric shape. We discuss the nature of the phase transition, the role of interface tension, and the phase diagram. The symmetric to asymmetric transition is the simplest quantum phase transition that one can imagine. Careful study of this problem should provide us insight into this burgeoning field of discovery. © 2003 The American Physical Society URL:
