Renormalization group approach for the scattering off a single Rashba impurity in a helical liquid
François Crépin, Jan Carl Budich, Fabrizio Dolcini +2
The occurrence of two-particle inelastic backscattering has been conjectured in helical edge states of topological insulators and is expected to alter transport. In this Letter, by…
Incompressible states of a two-component Fermi gas in a double-well optical lattice
François Crépin, Roberta Citro, Pascal Simon
We propose a scheme to investigate the effect of frustration on the magnetic phase transitions of cold atoms confined in an optical lattice. We also demonstrate how to get two-leg…
Disordered one-dimensional Bose-Fermi mixtures: The Bose-Fermi glass
François Crépin, Gergely Zaránd, Pascal Simon
We analyze an interacting Bose-Fermi mixture in a 1D disordered potential using a combination of renormalization group and variational methods. We obtain the complete phase diagram…
