Determination of Chern numbers with a phase retrieval algorithm
Tomasz Szołdra, Krzysztof Sacha, Arkadiusz Kosior
Ultracold atoms in optical lattices form a clean quantum simulator platform which can be utilized to examine topological phenomena and test exotic topological materials. Here we pr…
Dynamical quantum phase transitions in systems with broken continuous time and space translation symmetries
Arkadiusz Kosior, Andrzej Syrwid, Krzysztof Sacha
Spontaneous breaking of continuous time translation symmetry into a discrete one is related to time crystal formation. While the phenomenon is not possible in the ground state of a…
Time crystals: analysis of experimental conditions
Krzysztof Giergiel, Arkadiusz Kosior, Peter Hannaford +1
Time crystals are quantum many-body systems which are able to self-organize their motion in a periodic way in time. Discrete time crystals have been experimentally demonstrated in…
Unruh effect for interacting particles with ultracold atoms
Arkadiusz Kosior, Maciej Lewenstein, Alessio Celi
The Unruh effect is a quantum relativistic effect where the accelerated observer perceives the vacuum as a thermal state. Here we propose the experimental realization of the Unruh…
