Dynamical quantum phase transitions in discrete time crystals
Arkadiusz Kosior, Krzysztof Sacha
Discrete time crystals are related to non-equilibrium dynamics of periodically driven quantum many-body systems where the discrete time translation symmetry of the Hamiltonian is s…
Time crystal platform: from quasi-crystal structures in time to systems with exotic interactions
Krzysztof Giergiel, Artur Miroszewski, Krzysztof Sacha
Time crystals are quantum many-body systems which, due to interactions between particles, are able to spontaneously self-organize their motion in a periodic way in time by analogy…
Many-body localization caused by temporal disorder
Marcin Mierzejewski, Krzysztof Giergiel, Krzysztof Sacha
The many-body localization (MBL) is commonly related to a strong spatial disorder. We show that MBL may alternatively be generated by adding a temporal disorder to periodically dri…
Quantum dark solitons in Bose gas confined in a hard wall box
Andrzej Syrwid, Krzysztof Sacha
Schrödinger equation for Bose gas with repulsive contact interactions in one-dimensional space may be solved analytically with the help of the Bethe ansatz if we impose periodic bo…
Time crystals: a review
Krzysztof Sacha, Jakub Zakrzewski
Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in 2012. While the original concept was strongly criticized, it stimulated at the same time an…
Anderson localization of a Rydberg electron along a classical orbit
Krzysztof Giergiel, Krzysztof Sacha
Anderson localization is related to exponential localization of a particle in the configuration space in the presence of a disorder potential. Anderson localization can be also obs…
