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…
Controlled preparation of phases in two-dimensional time crystals
Arkadiusz Kuros, Rick Mukherjee, Florian Mintert +1
The study of phases is useful for understanding novel states of matter. One such state of matter are time crystals which constitute periodically driven interacting many-body system…
Discrete Time Quasi-Crystals
Krzysztof Giergiel, Arkadiusz Kuroś, Krzysztof Sacha
Between space crystals and amorphous materials there exists a third class of aperiodic structures which lack translational symmetry but reveal long-range order. They are dubbed qua…
Two-electron resonances in quasi-one dimensional quantum dots with Gaussian confinement
Arkadiusz Kuroś, Anna Okopińska
We consider a quasi one-dimensional quantum dot composed of two Coulombically interacting electrons confined in a Gaussian trap. Apart from bound states, the system exhibits resona…
Coupled anharmonic oscillators: the Rayleigh-Ritz approach versus the collocation approach
Arkadiusz Kuros, Anna Okopinska
For a system of coupled anharmonic oscillators we compare the convergence rate of the variational collocation approach presented recently by Amore and Fernandez (2010 Phys.Scr.81 0…
