Interaction enhanced altermagnet in the Hatsugai-Kohmoto model
Ádám Bácsi, Balázs Dóra
We investigate the interplay between altermagnetic band structures and electronic correlations by focusing on the altermagnetic generalization of the Hatsugai-Kohmoto…
Systematic Schrieffer-Wolff-transformation approach to Josephson junctions: quasiparticle effects and Josephson harmonics
Ádám Bácsi, Teodor Iličin, Rok Žitko
We use the Schrieffer-Wolff transformation (SWT) to analyze Josephson junctions between superconducting leads described by the charge-conserving BCS theory. Starting from the singl…
Vaporization dynamics of a dissipative quantum liquid
Ádám Bácsi, Catalin Pascu Moca, Gergely Zaránd +1
We investigate the stability of a Luttinger liquid, upon suddenly coupling it to a dissipative environment. Within the Lindblad equation, the environment couples to local currents…
Optimal protocols for finite-duration quantum quenches in the Luttinger model
Ádám Bácsi, Masudul Haque, Balázs Dóra
Reaching a target quantum state from an initial state within a finite temporal window is a challenging problem due to non-adiabaticity. We study the optimal protocol for swithcing…
Low frequency optical conductivity in graphene and in other scale-invariant two-band systems
Ádám Bácsi, Attila Virosztek
We investigate optical transitions of non-interacting electron systems consisting of two symmetric energy bands touching each other at the Fermi energy (e.g. graphene at half filli…
