A strange metal with a small Fermi surface and strong collective excitations

Abstract

We develop a theory of a hybrid state, where quasi-particles coexist with strong collective modes, taking as a starting point a model of infinitely many 1D Mott insulators coupled by a weak interchain tunneling. This state exists at an intermediate temperature range and undergoes an antiferromagnetic phase transition at temperatures much smaller than the Mott-Hubbard gap. The most peculiar feature of the hybrid state is that the volume of the Fermi surface is unrelated to the electron density. We present a self-consistent derivation of the low energy effective action for our model.
