Relaxation dynamics of the Holstein polaron
Denis Golež, Janez Bonča, Lev Vidmar +1
Keeping the full quantum nature of the problem we compute the relaxation time of the Holstein polaron after it was driven far from the equilibrium by a strong oscillatory pulse. Ju…
Nonequilibrium propagation and decay of a bound pair in driven t-J models
J. Bonca, M. Mierzejewski, L. Vidmar
We perform an accurate time-dependent numerical study of out-of-equilibrium response of a bound state within t-J systems on a two-leg ladder and a square lattice. We show that the…
Effective approach to the Nagaoka regime of the two dimensional t-J model
M. M. Maska, M. Mierzejewski, E. A. Kochetov +3
We argue that the t-J model and the recently proposed Ising version of this model give the same physical picture of the Nagaoka regime for J/t << 1. In particular, both models are…
