Renormalization group study of the one dimensional quantum mechanical XY model

  • Hu, Bambi

Abstract

The one dimensional quantum mechanical XY model is studied by the renormalization group method. To second order in the cumulant expansion, no non-trivial fixed points are found. The calculated free energy is in excellent agreement with that of the exact solution.
