Quantum phase transition from a superfluid to a Mott insulator in a gas of ultracold atoms
Markus Greiner, Olaf Mandel, Tilman Esslinger +2
For a system at a temperature of absolute zero, all thermal fluctuations are frozen out, while quantum fluctuations prevail. These microscopic quantum fluctuations can induce a mac…

Observation of Nagaoka Polarons in a Fermi-Hubbard Quantum Simulator
Martin Lebrat, Muqing Xu, Lev Haldar Kendrick +7
Quantum interference can deeply alter the nature of many-body phases of matter. In the paradigmatic case of the Hubbard model, Nagaoka famously proved that introducing a single iti…
