Crossover from adiabatic to sudden interaction quench in a Luttinger liquid
Balázs Dóra, Masudul Haque, Gergely Zaránd
Motivated by recent experiments on interacting cold atoms, we analyze interaction quenches in Luttinger liquids (LL), where the interaction is ramped from zero to a finite value wi…
Non-equilibrium frequency-dependent noise through a quantum dot: A real time functional renormalization group approach
C. P. Moca, P. Simon, C. H. Chung +1
We construct a real time current-conserving functional renormalization group (RG) scheme on the Keldysh contour to study frequency-dependent transport and noise through a quantum d…
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…
Theory of anisotropic Rashba splitting of surface states
E. Simon, A. Szilva, B. Ujfalussy +3
We investigate the surface Rashba effect for a surface of reduced in-plane symmetry. Formulating a k.p perturbation theory, we show that the Rashba splitting is anisotropic, in agr…
