Numerical simulations of merging dipolar supersolid fragments show damped crystal oscillations reflecting superfluid connectivity and out-of-phase drifts indicating second sound excitation via phase-imprinted dark solitons.
A non-Gaussian variational ansatz computes 2D Fermi polaron ground-state energy, residue, and spectral functions, agreeing qualitatively with Monte Carlo while revealing oscillatory or relaxational dynamics to the molecular state.

Efficient variational approach to the Fermi polaron problem in two dimensions, both in and out of equilibrium
A non-Gaussian variational ansatz computes 2D Fermi polaron ground-state energy, residue, and spectral functions, agreeing qualitatively with Monte Carlo while revealing oscillatory or relaxational dynamics to the molecular state.
