Symmetry-breaking Fermi surface deformations from central interactions in two dimensions
arXiv:0805.4623 · doi:10.1103/PhysRevB.78.035131
Abstract
We present a mean field theory of the Pomeranchuk instability in two dimensions, starting from a generic central interaction potential described in terms of a few microscopic parameters. For a significant range of parameters, the instability is found to be pre-empted by a first-order quantum phase transition. We provide the ground state phase diagram in terms of our generic parameters.
