Quantum simulations of electronic structure and strongly correlated quantum phases are widely regarded as among the most promising applications of quantum computing. These computat…
Quantum-gas microscopy and Talbot interferometry of the Bose-glass phase
Lennart Koehn, Christopher Parsonage, Callum W. Duncan +6
Disordered potentials fundamentally affect transport and coherence in quantum systems, giving rise to a Bose-glass phase in interacting bosonic systems -- an insulating yet compres…
Experimental Observation of Single- and Multisite Matter-Wave Solitons in an Optical Accordion Lattice
Robbie Cruickshank, Francesco Lorenzi, Arthur La Rooij +5
We report the experimental observation of discrete bright matter-wave solitons with attractive interaction in an optical lattice. Using an accordion lattice with adjustable spacing…
Observation of emergent scaling of spin-charge correlations at the onset of the pseudogap
Thomas Chalopin, Petar Bojović, Si Wang +12
In strongly correlated materials, interacting electrons are entangled and form collective quantum states, resulting in rich low-temperature phase diagrams. Notable examples include…

Optical superlattice for engineering Hubbard couplings in quantum simulation
Thomas Chalopin, Petar Bojović, Dominik Bourgund +4
Quantum simulations of Hubbard models with ultracold atoms rely on the exceptional control of coherent motion provided by optical lattices. Here we demonstrate enhanced tunability…
Formation of stripes in a mixed-dimensional cold-atom Fermi-Hubbard system
Dominik Bourgund, Thomas Chalopin, Petar Bojović +8
The relation between d-wave superconductivity and stripes is fundamental to the understanding of ordered phases in cuprates. While experimentally both phases are found in close pro…

Ultracold polyatomic molecules offer intriguing new opportunities in cold chemistry, precision measurements, and quantum information processing, thanks to their rich internal struc…
Universal equation of state for wave turbulence in a quantum gas
Lena H. Dogra, Gevorg Martirosyan, Timon A. Hilker +6
Boyle's 1662 observation that the volume of a gas is, at constant temperature, inversely proportional to pressure, offered a prototypical example of how an equation of state (EoS)…
