V magistrskem delu je obravnavana kvantizacija prevodnosti v 4-terminalnem Josephsonovem stiku v prisotnosti Rashbove interakcije. Najprej je predstavljen Bogoljubov-de Gennesov formalizem za običajni superprevodnik. Podrobneje so predstavljene lastne energije in lastna stanja v enodimenzionalnem su ...

Simulation of the COVID-19 epidemic on the social network of Slovenia: estimating the intrinsic forecast uncertainty
Žiga Zaplotnik, Aleksandar Gavrić, Luka Medic
Izvirni znanstveni članek
Oznake: koronavirus COVID-19;epidemije;socialne mreže;Slovenija;COVID-19;epidemiology;Slovenia;social networks;
In the article a virus transmission model is constructed on a implified social network. The social network consists of more than 2 million nodes, each representing an inhabitant of Slovenia. The nodes are organised and interconnected according to the real household and elderly-care center distributi ...

Extending third quantization with commuting observables: a dissipative spin-boson model
Luka Medic, Anton Ramšak, Tomaž Prosen
Izvirni znanstveni članek
Oznake: kvantna mehanika;tretja kvantizacija;model spin-bozon;quantum mechanics;third quantization;spin-boson model;
We consider the spectral and initial value problem for the Lindblad–Gorini–Kossakowski–Sudarshan master equation describing an open quantum system of bosons and spins, where the bosonic parts of the Hamiltonian and Lindblad jump operators are quadratic and linear respectively, while the spins couple ...

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 ...
