Electronic correlations and transport in multi-orbital systems
Alen Horvat, Jernej Mravlje
Doktorska disertacija
Oznake: condensed matter physics;multi-orbital systems;electronic transport;Kondo effect;magnetic properties;Hundʼs metals;spin-orbit coupling;numerical renormalization group;
We investigate electronic correlations and transport in multi-orbital models with Hund’s rule coupling. Recent theoretical investigations of multi-orbital models pointed out the vital role of the Hund’s rule coupling, which induces strong correlations away from the Mott transition, suppresses the co ...

Non-equilibrium dynamics of topological insulators
Lara Ulčakar, Tomaž Rejec, Jernej Mravlje
Doktorska disertacija
Oznake: non-equilibrium dynamics;topological insulators;quantum phase transitions;quenches;time-reversal symmetry;Chern insulator;Hall effect;
Topological insulators are band insulators with a non-trivial band topology that leads to the presence of in-gap edge states at the boundaries and the associated dissipationless transport. The thesis is focused on non-equilibrium behaviour that arises when a topological insulator is slowly quenched ...

Transport and diffusion of charge, spin, and heat in the two-dimensional Hubbard model
Martin Ulaga, Jure Kokalj, Jernej Mravlje
Doktorska disertacija
Oznake: electronic correlations;Hubbard model;Heisenberg model;transport;spin bad metal;spin diffusion;heat diffusion;thermoelectric effect;Lorenz number;
This thesis addresses transport questions in strongly correlated electronic systems in two dimensions. The primary tool for the analysis is the exact numerical treatment of the problem on small clusters, which allows for a description of transport at high temperatures, combined with dynamical mean-f ...

Topološki sistemi izven ravnovesja: počasne deformacije v modelu Su-Schrieffer-Heeger
Sara Pia Marinček, Jernej Mravlje, Tomaž Rejec
Magistrsko delo
Oznake: fizika kondenzirane snovi;topološki izolatorji;model Su-Schrieffer-Heeger;ovojno število;robna stanja;
V tem delu obravnavamo topološke sisteme izven ravnovesja, pri čemer neravnovesno stanje dosežemo s preklopom parametrov hamiltonjana med topološko različnimi režimi. Preučujemo odziv sistema, ki je na začetku v osnovnem stanju enodimenzionalnega modela Su-Schrieffer-Heeger (SSH), na počasne deforma ...

High-harmonic generation in semi-Dirac and Weyl semimetals with broken time-reversal symmetry: exploration of the merging of Weyl nodes
Luka Medic, Jernej Mravlje, Anton Ramšak, Tomaž Rejec
Izvirni znanstveni članek
Oznake: fizika kondenzirane snovi;condensed matter physics;
We explore anomalous high-harmonic generation in a model that realizes a transition from a broken time-reversal symmetry Weyl semimetal to a semi-Dirac regime, i.e., a gapless semimetal with dispersion that is parabolic in one direction and conical in the other two. We point out the intensity of the ...
