Large anomalous shifts of potassium-39 Feshbach resonances
Ali Zaheer, Mohammed Bouras, Krzysztof Giergiel +3
We report the observation of large anomalous shifts, up to +7.5 G, of the positions of the 33.6 G and 39.9 G Feshbach resonances in potassium-39 atoms confined in a 1063.9 nm optic…
Quantum-Coherent Regime of Programmable Dipolar Spin Ice
Krzysztof Giergiel, Piotr Surówka
Frustrated spin-ice systems support emergent gauge fields and fractionalized quasiparticles that act as magnetic monopoles. Although artificial platforms have enabled their direct…
Hybrid Quantum-Classical Scheduling with Problem-Aware Calibration on a Quantum Annealer
Krzysztof Giergiel, Y. Sam Yang, Anthony B. Murphy
We evaluate the application of quantum annealing (QA) to a real-world combinatorial optimisation problem-room scheduling for sports camps at the Australian Institute of Sport-using…
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…
