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…
Topological Molecules and Topological Localization of a Rydberg Electron on a Classical Orbit
Ali Emami Kopaei, Xuedong Tian, Krzysztof Giergiel +1
It is common knowledge that atoms can form molecules if they attract each other. Here, we show that it is possible to create molecules where bound states of the atoms are not the r…
Topologically protected quantization of work
Bruno Mera, Krzysztof Sacha, Yasser Omar
The transport of a particle in the presence of a potential that changes periodically in space and in time can be characterized by the amount of work needed to shift a particle by a…
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…
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…
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…
