Flow equations and normal ordering

Elmar Körding1 and Franz Wegner

Show affiliations


In this paper we consider flow equations where we allow a normal ordering which is adjusted to the one-particle energy of the Hamiltonian. We show that this flow nearly always converges to the stable phase. Starting out from the symmetric Hamiltonian and symmetry-broken normal ordering nearly always yields symmetry breaking below the critical temperature.
