• Authors: Pranay Nayak, Ratheejit Ghosh, Rejish Nath,
• Abstract summary: We show that the density of a em target dipolar Bose-Einstein condensate can be axially confined and engineered using a trapped em control dipolar condensate. The latter leads to a structural transition between single and double-peaked structures with coherence between the peaks controlled via the separation between the control condensates.

• Abstract: We study the effect of inter-condensate dipole-dipole interactions in a setup consisting of physically disconnected, single-species dipolar Bose-Einstein condensates. In particular, making use of the long-range and anisotropic nature of dipole-dipole interactions, we show that the density of a {\em target} dipolar Bose-Einstein condensate can be axially confined and engineered using a trapped {\em control} dipolar condensate. Increasing the number of control condensates leads to exotic ground state structures, including periodic patterns in the target condensate. The latter leads to a structural transition between single and double-peaked structures with coherence between the peaks controlled via the separation between the control condensates.

  We study the photon-dipole interactions between emitters dispersively coupled to the photonic analogue of a flat band (FB) We show that the strength of such photon-mediated interactions decays exponentially with distance with a characteristic localization length. We find that the localization length grows with the overlap between CLSs according to an analytically-derived universal scaling law valid for a large class of FBs both in 1D and 2D.

  We investigate the merging behaviour of two identical supersolids through dipolar Bose-Einstein condensates confined within a double-well potential. By adiabatically tuning the barrier height and the spacing between the two wells, the two supersolids move toward each other and lead to the emergence of a variety of ground state phases. We calculate the force required to pull the two portions of the gas apart, finding that the merged supersolids act like a deformable plastic material.

  We investigate the dynamics and stationary states of a semiconductor exciton-polariton condensate in a double well potential. We find that upon the population build up of the polaritons by above-threshold laser pumping, coherence relaxation due to the phase fluctuations of the polaritons drives the system into a stable fixed point corresponding to a self-organized PT-symmetric phase.
