  • Self-bound supersolid stripe phase in binary Bose-Einstein condensates
    2020
    Co-Authors: Sachdeva Rashi, Tengstrand, Mikael Nilsson, Reimann, Stephanie M.
    Abstract:

    Supersolidity - a coexistence of superfluidity and crystalline or Amorphous Density variations - has been vividly debated ever since its conjecture. While the initial focus was on helium-4, recent experiments uncovered supersolidity in ultra-cold dipolar quantum gases. Here, we propose a new self-bound supersolid phase in a binary mixture of Bose gases with short-range interactions, making use of the non-trivial properties of spin-orbit coupling. We find that a first-order phase transition from a self-bound supersolid stripe phase to a zero-minimum droplet state of the Bose gas occurs as a function of the Rabi coupling strength. These phases are characterized using the momentum distribution, the transverse spin polarization and the superfluid fraction. The critical point of the transition is estimated in an analytical framework. The predicted Density-modulated supersolid stripe and zero-minimum droplet phase should be experimentally observable in a binary mixture of $^{39}$K with spin-orbit coupling.Comment: 5 pages, 3 figure
