Topological quantum phase transition in the BEC-BCS crossover phenomena (1003.4735v1)
Published 24 Mar 2010 in cond-mat.str-el
Abstract: A crossover between the Bose Einstein condensation (BEC) and BCS superconducting state is described topologically in the chiral symmetric fermion system with attractive interaction. Using a local Z_2 Berry phase, we found a quantum phase transition between the BEC and BCS phases without accompanying the bulk gap closing.
