Superconducting zero-temperature phase transition in two dimensions and in a magnetic field - art. no. 184503

摘要

We derive the Ginzburg-Landau- Wilson theory for the superconducting phase transition in two dimensions and in the magnetic field. Without disorder the theory describes a fluctuation induced first-order quantum phase transition into the Abrikosov lattice. We propose a phenomenological criterion for determining the transition field and discuss the qualitative effects of disorder. Comparison with recent experiments on MoGe films is discussed.
