Strongly Interacting Two-Dimensional Bose Gases

Abstract: We prepare and study strongly interacting two-dimensional Bose gases in the superfluid, the classical Berezinskii-Kosterlitz-Thouless (BKT) transition, and the vacuum-to-superfluid quantum critical regimes. A wide range of the two-body interaction strength 0.05 < g < 3 is covered by tuning the scattering length and by loading the sample into an optical lattice. Based on the equations of state measurements, we extract the coupling constants as well as critical thermodynamic quantities in different regimes. In t… Show more

“…The strongly interacting regime of this crossover may be relevant to hightemperature superconductors: While the superconducting phase of the cuprates has d-wave symmetry [2], the s-wave symmetry has been detected in the pseudogap phase [10]. Exploring the Bose part of the crossover complements studies of interacting 2D Bose gases [11] by reaching stronger interactions. Studying the fermionic side may add to the understanding of 2D Fermi liquids.…”

“…The motion in the third direction is assumed to be frozen by an additional, tight harmonic confinement, as realized in current experiments [4][5][6][7]. First and second sound of the system are described by Landau's two-fluid hydrodynamic equations which involve only local thermodynamic variables and superfluid density.…”

“…In particular, in a milestone experiment performed by the Innsbruck team [16], first and second sound waves were excited in the highly elongated unitary Fermi gas, and their propagations along the weakly confined axis were measured. These measurements are straightforward to implement in a trapped 2D Bose or Fermi gas, and would greatly promote the current experimental [4][5][6][7] and theoretical research [17][18][19] on the intriguing BKT physics in ultracold atoms and solid-state systems.…”
