Enhanced Drude weight in a 1D system of fermions with pair hopping events
M. S. Bahovadinov, R. O. Sharipov, B. L. Altshuler +1
In one dimension density-density interactions of particles reduce their mobility and hence the Drude weight, which controls the divergence of the optical conductivity at zero frequ…
Many-body localization of 1D disordered impenetrable two-component fermions
M. S. Bahovadinov, D. V. Kurlov, B. L. Altshuler +1
We study effects of disorder on eigenstates of 1D two-component fermions with infinitely strong Hubbard repulsion. We demonstrate that the spin-independent (potential) disorder red…
Finite temperature disordered bosons in two dimensions
G. Bertoli, V. P. Michal, B. L. Altshuler +1
We study phase transitions in a two dimensional weakly interacting Bose gas in a random potential at finite temperatures. We identify superfluid, normal fluid, and insulator phases…
Finite temperature phase transition for disordered weakly interacting bosons in one dimension
I. L. Aleiner, B. L. Altshuler, G. V. Shlyapnikov
It is commonly accepted that there are no phase transitions in one-dimensional (1D) systems at a finite temperature, because long-range correlations are destroyed by thermal fluctu…
