Quantum-disentangled liquid in the half-filled Hubbard model
Thomas Veness, Fabian H. L. Essler, Matthew P. A. Fisher
We investigate the existence of quantum disentangled liquid (QDL) states in the half-filled Hubbard model on bipartite lattices. In the one dimensional case we employ a combination…
Mobile impurity approach to the optical conductivity in the Hubbard chain
Thomas Veness, Fabian H. L. Essler
We consider the optical conductivity in the one dimensional Hubbard model in the metallic phase close to half filling. In this regime most of the spectral weight is located at freq…
Optical conductivity of the Hubbard chain away from half filling
Alexander C. Tiegel, Thomas Veness, Piet E. Dargel +4
We consider the optical conductivity in the metallic phase of the one-dimensional Hubbard model. Our results focus on the vicinity of half filling and the frequency regime…
