Magnetism and superconductivity of strongly correlated electrons on the triangular lattice
Cédric Weber, Andreas Laeuchli, Frédéric Mila +1
We investigate the phase diagram of the \tj Model on a triangular lattice using a Variational Monte-Carlo approach. We use an extended set of Gutzwiller projected fermionic trial w…
Non-equilibrium relaxation of an elastic string in a random potential
Alejandro Kolton, Alberto Rosso, Thierry Giamarchi
We study the non--equilibrium motion of an elastic string in a two dimensional pinning landscape using Langevin dynamics simulations. The relaxation of a line, initially flat, is c…
Coulombian Disorder in Periodic Systems
E. Orignac, A. Rosso, R. Chitra +1
We study the effect of unscreened charged impurities on periodic systems. We show that the long wavelength component of the disorder becomes long ranged and dominates static correl…
Spin-1/2 fermions on spin-dependent optical lattices
M. A. Cazalilla, A. F. Ho, T. Giamarchi
We study the phase diagram of one dimensional spin one-half fermionic cold atoms. The two ``spin'' species can have different hopping or mass. The phase diagram at equal densities…
Adiabatic-antiadiabatic crossover in a spin-Peierls chain
R. Citro, E. Orignac, T. Giamarchi
We consider an XXZ spin-1/2 chain coupled to optical phonons with non-zero frequency . In the adiabatic limit (small ), the chain is expected to spontaneously dimerize an…
Keldysh study of point-contact tunneling between superconductors
C. J. Bolech, T. Giamarchi
We revisit the problem of point-contact tunnel junctions involving one-dimensional superconductors and present a simple scheme for computing the full current-voltage characteristic…
