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…
Bose-Hubbard realization of fracton defects
Krzysztof Giergiel, Ruben Lier, Piotr Surówka +1
Bose-Hubbard models are simple paradigmatic lattice models used to study dynamics and phases of quantum bosonic matter. We combine the extended Bose-Hubbard model in the hard-core…
Inseparable time-crystal geometries on the Möbius strip
Krzysztof Giergiel, Arkadiusz Kuroś, Arkadiusz Kosior +1
Description of periodically and resonantly driven quantum systems can lead to solid state models where condensed matter phenomena can be investigated in time lattices formed by per…
Anderson Molecules
Paweł Matus, Krzysztof Giergiel, Krzysztof Sacha
Atoms can form molecules if they attract each other. Here, we show that atoms are also able to form bound states not due to the attractive interaction but because of destructive in…
Phase diagram and optimal control for n-tupling discrete time crystal
Arkadiusz Kuroś, Rick Mukherjee, Weronika Golletz +4
A remarkable consequence of spontaneously breaking the time translational symmetry in a system, is the emergence of time crystals. In periodically driven systems, discrete time cry…
Creating big time crystals with ultracold atoms
Krzysztof Giergiel, Tien Tran, Ali Zaheer +4
We investigate the size of discrete time crystals s (ratio of response period to driving period) that can be created for a Bose-Einstein condensate (BEC) bouncing resonantly on an…
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…
Time crystals: analysis of experimental conditions
Krzysztof Giergiel, Arkadiusz Kosior, Peter Hannaford +1
Time crystals are quantum many-body systems which are able to self-organize their motion in a periodic way in time. Discrete time crystals have been experimentally demonstrated in…
Topological Time Crystals
K. Giergiel, A. Dauphin, M. Lewenstein +2
By analogy with the formation of space crystals, crystalline structures can also appear in the time domain. While in the case of space crystals we often ask about periodic arrangem…
Time crystal platform: from quasi-crystal structures in time to systems with exotic interactions
Krzysztof Giergiel, Artur Miroszewski, Krzysztof Sacha
Time crystals are quantum many-body systems which, due to interactions between particles, are able to spontaneously self-organize their motion in a periodic way in time by analogy…
