arXiv:cond-mat/0110627 · doi:10.1103/PhysRevLett.88.167001
Abstract
We study the dynamics of the Mott insulator-superfluid quantum phase transition in a periodic 1D array of Josephson junctions. We show that crossing the critical point diabatically i.e. at a finite rate with a quench time induces finite quantum fluctuations of the current around the loop proportional to . This scaling could be experimentally verified with in array of weakly coupled Bose-Einstein condensates or superconducting grains.
