Trapping and cooling fermionic atoms into the Mott and Néel states
L. De Leo, C. Kollath, A. Georges +2
We perform a theoretical study of a fermionic gas with two hyperfine states confined to an optical lattice. We derive a generic state diagram as a function of interaction strength,…
Valence-Bond Dynamical Mean-Field Theory of Doped Mott Insulators with Nodal/Antinodal Differentiation
M. Ferrero, P. S. Cornaglia, L. De Leo +3
We introduce a valence-bond dynamical mean-field theory of doped Mott insulators. It is based on a minimal cluster of two orbitals, each associated with a different region of momen…
T=0 heavy fermion quantum critical point as an orbital selective Mott transition
Lorenzo De Leo, Marcello Civelli, Gabriel Kotliar
We describe the T=0 quantum phase transition in heavy fermion systems as an orbital selective Mott transition (OSMT) using a cluster extension of dynamical mean field theory. This…
Surprises in the phase diagram of an Anderson impurity model for a single C molecule
L. De Leo, M. Fabrizio
We find by Wilson numerical renormalization group and conformal field theory that a three-orbital Anderson impurity model for a C molecule has a very rich phase diagram…
Non-trivial fixed point in a twofold orbitally degenerate Anderson impurity model
Michele Fabrizio, Andrew F. Ho, Lorenzo De Leo +1
We study the phase diagram of a twofold orbitally degenerate Anderson impurity model which presents a non-trivial fixed point similar to the two-impurity Kondo model one. Remarkabl…
