Symphony on Strong Field Approximation
Kasra Amini, Jens Biegert, Francesca Calegari +22
This paper has been prepared by the Symphony collaboration (University of Warsaw, Uniwersytet Jagielloński, DESY/CNR and ICFO) on the occasion of the 25th anniversary of the "simpl…
Fractional Time Crystals
Pawel Matus, Krzysztof Sacha
Time crystals are quantum systems which are able to reveal condensed matter behavior in the time domain. It is known that crystalization in time can be observed in a periodically d…
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…
Quantum measurements of time
Lorenzo Maccone, Krzysztof Sacha
We propose a time-of-arrival operator in quantum mechanics by conditioning on a quantum clock. This allows us to bypass some of the problems of previous proposals, and to obtain a…
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…
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…
