Local moment and specific heat in the Hubbard model
Source abstract
Abstract
Abstract We discuss the local moment and specific heat of the two-dimensional half-filled Hubbard model. For small values of U the local moment displays not only a strucure at T∼U, but also an additional increase at low T, leading to a two-peak structure for C(T) down to U=t.
