Hybridizing localized and itinerant electrons: a recipe for pseudogaps
E. A. Winograd, L. de' Medici
In a system where selective Mott localization is realized, some electrons show a gap to charge excitations while others do not. A hybridization between these two kind of electrons…
Phase diagram of the asymmetric Hubbard model and an entropic chromatographic method for cooling cold fermions in optical lattices
E. A. Winograd, R. Chitra, M. J. Rozenberg
We study the phase diagram of the asymmetric Hubbard model (AHM), which is characterized by different values of the hopping for the two spin projections of a fermion or equivalentl…
Orbital selective crossover and Mott transitions in an asymmetric Hubbard model of cold atoms in optical lattices
E. A. Winograd, R. Chitra, M. J. Rozenberg
We study the asymmetric Hubbard model at half-filling as a generic model to describe the physics of two species of repulsively interacting fermionic cold atoms in optical lattices.…
Weak coupling study of decoherence of a qubit in disordered magnetic environments
E. A. Winograd, M. J. Rozenberg, R. Chitra
We study the decoherence of a qubit weakly coupled to frustrated spin baths. We focus on spin-baths described by the classical Ising spin glass and the quantum random transverse Is…
