Works:

We study many-body electron dynamics in a strongly correlated ultracold Rydberg gas. A broadband picosecond laser pulse is utilized to excite ultracold Rydberg atoms in an optical lattice to their Rydberg states, generating a high-density ensemble of Rydberg atoms interacting with each other. We have successfully observed non-equilibrium electron dynamics that follows this broadband Rydberg excitation. We have also studied symmetry restoration of an electron wave packet in an ultracold rubidium atom in a magnet optical trap, using two circularly polarized laser pulses resonant with its Rydberg transition. The first pulse breaks the symmetry, which is restored with the second pulse. The laser pulse for symmetry restoration is designed as copy of the pulse for symmetry breaking. Symmetry restoration is achieved by tuning the interpulse delay on the attosecond timescale. The result has been published in Phys. Rev. Lett. 121, 173201 (2018).
