We investigate the dynamical effects of electron-phonon coupling (EPC) on the superconducting properties of two-dimensional (2D) systems, calculating the Eliashberg function in terms of dynamically renormalized phonons. By studying different approxim

Dynamical conductivity in a disordered one-dimensional model of interacting fermions is studied numerically at high temperatures and in the weak-interaction regime in order to find a signature of many-body localization and vanishing d.c. transport co

We explore the effect of a (non-)magnetic impurity on the thermal transport of the spin-1/2 Heisenberg chain model. This unique system allows to probe Kondo-type phenomena in a prototype strongly correlated system. Using numerical diagonalization tec

Uz dovoljno jako elektron-fononsko međudjelovanje transportna svojstva nosilaca naboja male gustoće prate polaronski učinci koji su utvrđeni u brojnim eksperimentima. Postoji niz pokazatelja da su učinci polaronskog tipa značajni za materijale

Holsteinov model opisuje elektrone u aproksimaciji čvrste veze koji međudjeluju s jednom granom optičkih nedisperzivnih fonona. U ovom radu, rabeći pet različitih varijacijskih i numeričkih metoda, razmatrana su polaronska stanja ovog modela ko

The effect of the quenched random dilution on the ferromagnetic transitions, in particular, the conversion from the first- to second-order transition is discussed. The new results are presented for the diluted three-dimensional three-state Potts mode

This thesis deals with several problems in condensed matter theory involving strong correlations and/or a disorder. It is divided into four parts, with the effects of electron-phonon interaction appearing as the key subject of the first three parts.
