Mott Quantum Critical Points at finite doping
Maria Chatzieleftheriou, Alexander Kowalski, Maja Berović +5
Strongly correlated materials often undergo a Mott metal-insulator transition, which is tipically first-order, as a function of control parameters like pressure. Upon doping, rich…
Pseudogap opening and formation of Fermi arcs as an orbital-selective Mott transition in momentum space
M. Ferrero, P. S. Cornaglia, L. De Leo +3
We present an approach to the normal state of cuprate superconductors which is based on a minimal cluster extension of dynamical mean-field theory. Our approach is based on an effe…
Ferromagnetic Kondo Effect at Nanocontacts
Paola Gentile, Lorenzo De Leo, Michele Fabrizio +1
Magnetic impurities bridging nanocontacts and break junctions of nearly magnetic metals may lead to permanent moments, analogous to the giant moments well known in the bulk case. A…
Getting into Shape: Efficient Cooling Scheme for Fermionic Atoms in Optical Lattices
Jean-Sebastien Bernier, Corinna Kollath, Antoine Georges +4
We propose an experimental procedure to cool fermionic atoms loaded into an optical lattice. The central idea is to spatially divide the system into entropy-rich and -poor regions…
Cellular Dynamical Mean Field Theory of the Periodic Anderson Model
Lorenzo De Leo, Marcello Civelli, Gabriel Kotliar
We develop a cluster dynamical mean field theory of the periodic Anderson model in three dimensions, taking a cluster of two sites as a basic reference frame. The mean field theory…
Phase diagram of the anisotropic multichannel Kondo Hamiltonian revisited
Avraham Schiller, Lorenzo De Leo
The phase diagram of the multichannel Kondo Hamiltonian with an XXZ spin-exchange anisotropy is revisited, revealing a far richer fixed-point structure than previously appreciated.…
