Ultrafast Many-Body Dynamics in an Ultracold Rydberg-Excited Atomic Mott Insulator
V. Bharti, S. Sugawa, M. Mizoguchi +7
We report the observation and control of ultrafast non-equilibrium many-body electron dynamics in Rydberg-excited spatially-ordered ultracold atoms created from a three-dimensional…
