Finite temperature transport in disordered Heisenberg chains
A. Karahalios, A. Metavitsiadis, X. Zotos +2
Using numerical diagonalization techniques, we explore the effect of local and bond disorder on the finite temperature spin and thermal conductivities of the one dimensional anisot…
The Friedel oscillations in the presence of transport currents
Anna Gorczyca, Maciej M. Maska, Marcin Mierzejewski
We investigate the Friedel oscillations in a nanowire coupled to two macroscopic electrodes of different potentials. We show that the wave-length of the density oscillations monoto…
Hofstadter butterfly for a finite correlated system
Katarzyna Czajka, Anna Gorczyca, Maciej M. Maska +1
We investigate a finite two-dimensional system in the presence of external magnetic field. We discuss how the energy spectrum depends on the system size, boundary conditions and Co…
