Topologically protected quantized changes of the distance between atoms
Ali Emami Kopaei, Krzysztof Giergiel, Krzysztof Sacha
Thouless pumping enables the transport of particles in a one-dimensional periodic potential if the potential is slowly and periodically modulated in time. The change in the positio…

Time-tronics: from temporal printed circuit board to quantum computer
Krzysztof Giergiel, Peter Hannaford, Krzysztof Sacha
Time crystalline structures can be created in periodically driven systems. They are temporal lattices which can reveal different condensed matter behaviours ranging from Anderson l…

Discrete Time Crystals with Absolute Stability
Krzysztof Giergiel, Jia Wang, Bryan J. Dalton +2
We show that interacting bosons on a ring which are driven periodically by a rotating potential can support discrete time crystals whose absolute stability can be proven. The absol…
