Response functions in multicomponent Luttinger liquids
E. Orignac, R. Citro
We derive an analytic expression for the zero temperature Fourier transform of the density-density correlation function of a multicomponent Luttinger liquid with different velociti…
Disorder in low dimensions: localisation effects in spin glass wires and cold atoms
David Carpentier, Edmond Orignac, Guillame Paulin +1
In this paper, we review the recent activity of our group on the study of disorder effects on systems displaying phase coherence. These studies have focused on both the electronic…
Superfluidity and Anderson localisation for a weakly interacting Bose gas in a quasiperiodic potential
Xiaolong Deng, Roberta Citro, Anna Minguzzi +1
Using exact diagonalisation and Density Matrix Renormalisation group (DMRG) approach, we analyse the transition to a localised state of a weakly interacting quasi-1D Bose gas subje…
Phase diagram and momentum distribution of an interacting Bose gas in a bichromatic lattice
Xiaolong Deng, R. Citro, A. Minguzzi +1
We determine the phase diagram and the momentum distribution for a one-dimensional Bose gas with repulsive short range interactions in the presence of a two-color lattice potential…
Role of interchain hopping in two disordered chains of spinless fermions
E. Orignac, Y. Suzumura, T. Giamarchi
The effect of interchain hopping and interaction on Anderson localization has been investigated for two coupled chains of spinless fermions with nearest neighbor interaction. Using…
Magnetism and superconductivity in underscreened Kondo chains
N. Andrei, E. Orignac
We present a one dimensional model of electrons coupled to localized moments of spin in which magnetism and superconductivity interplay in a nontrivial manner. This model…
