Generalized Gibbs ensembles in weakly interacting dissipative systems and digital quantum computers
Iris Ulčakar, Zala Lenarčič
Izvirni znanstveni članek
Oznake: prosti fermioni;free fermions;generalized Gibbs ensemble;Lindblad master equations;open quantum systems;
Identifying use cases with superconducting circuits not critically affected by the inherent noise is a pertinent challenge. Here, we propose using a digital quantum computer to showcase the activation of integrable effects in weakly dissipative integrable systems. Dissipation is realized by coupling ...

Iterative construction of conserved quantities in dissipative nearly integrable systems
Iris Ulčakar, Zala Lenarčič
Izvirni znanstveni članek
Oznake: fizika;kvantna fizika;kvantni sistemi;
Integrable systems offer rare examples of solvable many-body problems in the quantum world. Because of the fine-tuned structure, their realization in nature and experiment is never completely accurate, and therefore effects of integrability are observed only transiently. One way to overcome this lim ...

Vpliv disipacije na kvantne sisteme z lokalnimi omejitvami
Marko Aničin, Denis Golež, Zala Lenarčič
Magistrsko delo
Oznake: odprti kvantni sistemi;večdelčni kvantni sistemi;disipativna dinamika;kvantne večdelčne brazgotine;umeritvene teorije na mreži;kvantni simulatorji s hladnimi atomi;model PXP;kvantni povezavni model;
V magistrskem delu obravnavamo vpliv disipacije na dinamiko kvantnih večdelčnih sistemov z lokalnimi omejitvami, ki določajo dostopni del Hilbertovega prostora. Obravnavamo dva primera takšne omejene dinamike, ki ju je mogoče realizirati v kvantnih simulatorjih s hladnimi atomi: model PXP, ki opisuj ...

Spin subdiffusion in perturbed infinite-𝑈 Hubbard chain
J. Rękas, Marcin Mierzejewski, Zala Lenarčič, Peter Prelovšek
Izvirni znanstveni članek
Oznake: Hubbard model;Hilbert-space fragmentation;spin transport;strongly correlated electrons;
The t model represents the Hubbard model in the limit U →∞and is one of the basic models of stronglycorrelated electrons. On a one-dimensional chain, the model is integrable, and its charge dynamics is equivalentto that of free spinless fermions. However, within its dynamics the sequence of spins is ...

Doublon-holon pairing state in photodoped Mott insulators

We demonstrate the existence of an unconventional pairing state in photodoped Mott insulators on ladder and quasi-two-dimensional geometries, characterized by quasi-long-range doublon-holon correlations that signal Mott exciton condensation. The doublon-holon pairing exhibits correlations of d-wave- ...
