Eight-dimensional topological systems simulated using time-space crystalline structures
Yakov Braver, Egidijus Anisimovas, Krzysztof Sacha
We demonstrate the possibility of using time-space crystalline structures to simulate eight-dimensional systems based on only two physical dimensions. A suitable choice of system p…
Basis for time crystal phenomena in ultra-cold atoms bouncing on an oscillating mirror
Weronika Golletz, Andrzej Czarnecki, Krzysztof Sacha +1
We consider classical dynamics of a 1D system of particles bouncing on an oscillating mirror in the presence of gravitational field. The particles behave like hard balls and th…
Two-dimensional Thouless pumping in time-space crystalline structures
Y. Braver, C. -h. Fan, G. Žlabys +2
Dynamics of particle in a resonantly driven quantum well can be interpreted as that of a particle in a crystal-like structure, with the time playing the role of the coordinate. By…
When does a particle arrive?
Simone Roncallo, Krzysztof Sacha, Lorenzo Maccone
We compare the proposals that have appeared in the literature to describe a measurement of the time of arrival of a quantum particle at a detector. We show that there are multiple…
A Decade of Time Crystals: Quo Vadis?
Peter Hannaford, Krzysztof Sacha
Ten years ago, the new era of time crystals began. Time crystals are systems that behave in the time dimension like ordinary space crystals do in space dimensions. We present a bri…
Condensed matter physics in big discrete time crystals
Peter Hannaford, Krzysztof Sacha
We review the application of discrete time crystals created in a Bose-Einstein condensate (BEC) of ultracold atoms bouncing resonantly on an oscillating mirror to the investigation…
