HFSolver

The first heavy-fermion simulator for quantum criticality

written in Matlab and based on dynamical large-N Shwinger boson spin representation and independent bath approximation

Capable of

  • Modelling tetragonal (or other) Kondo lattices
  • Including anisotropic magnetic interactions
  • Including mixed valence
  • Computing varoious thermodynamical properties
    • Specific heat
    • Static/Dynamical Spin and Charge susceptibilities
