• Abstract: The nonequilibrium turbulent response of driven three-dimensional dipolar gases is monitored by dynamically crossing the supersolid-to-superfluid phase transition and vice versa utilizing a periodically modulated scattering length. Following the generation of vortical defects in the bulk, a direct cascade front emerges transporting energy from larger to smaller length scales and leading to a nonequilibrium quasi-steady state at long evolution times. This quasi-steady state is evidenced by the self-similar character of the momentum distributions featuring an algebraic reduction at large momenta with scaling exponents supporting the existence of wave turbulence. We observe that supersolidity sustaining higher-lying momenta, associated with the roton minimum, promotes the emergence of turbulence. Our results provide a stepping stone for unravelling and exploiting turbulent and self-similar behavior in anisotropically interacting quantum gases amenable in current experiments.

  We study subradiance in a Bose-Einstein condensate positioned at the mode crossing of two optical cavities. metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating. We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.

• Observation of an inverse turbulent-wave cascade in a driven quantum gas [0.0]
  We observe an inverse turbulent-wave cascade, from small to large lengthscales, in a homogeneous 2D Bose gas driven isotropically on a lengthscale much smaller than its size. At increasing lengthscales, the steady-state momentum distribution features in turn: (i) a power-law spectrum, with an exponent close to the analytical result for a particle cascade in weak-wave turbulence, and (ii) a spectrum intriguingly reminiscent of a nonthermal fixed point associated with universal coarsening in an isolated 2D gas.

  Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields. Near continuous phase transitions, associated with the divergence of a correlation length, universal power-law scaling behavior with critical exponents independent of microscopic system details is found.

Potential disorder reduces the amplitude of fluctuations of the quasisteady state current around its universal value. The lifetime of the quasisteady state remains nearly unaffected for disorder strengths up to the scale of the single-particle band gap.

  We quantum-simulate the reheating-like dynamics of a generic cosmological single-field model in an ultracold Bose gas. Expanding spacetime as well as the background oscillating inflaton field are mimicked in the non-relativistic limit. The proposed experiment has the potential of exploring the evolution up to late times even beyond the weak coupling regime.

  We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
