Interactions in Floquet-driven quantum gases cause unwanted heating and excitation modes. We found a general set of resonance conditions that explain this ‘‘Floquet heating’’ for superfluids in optical lattices. Phys. Rev. Research 6, 023323 (2024).
We use dynamically varying microscopic light potentials in a quantum-gas microscope to study commensurate and incommensurate 1D systems of interacting bosonic atoms in an optical lattice Nat Communications 15, 474 (2024).
We studied the stability of a Bosonic quantum gas in a 1D optical lattice with periodic driving, Phys. Rev. Research 5, 033024 (2023).
Accurate holographic light potentials using pixel crosstalk modelling Scientific Reports 13, 3252 (2023).
