dc.description.abstractWe analyze the role played by quantum fluctuations on a Raman spin-orbit-coupled system in the stripe phase under attractive interspin interactions. We show that beyond-mean-field effects stabilize the collapse predicted by mean-field theory for attractive enough interspin interactions and induce the emergence of two phases, a gas and a liquid, which also show spatial periodicity along a privileged direction. We show that the energetically favored phase is determined by the Raman coupling and the spin-dependent scattering lengths. We obtain the ground-state solution of the finite system by solving the extended Gross-Pitaevskii equation and find self-bound dropletlike solutions that feature internal structure through a striped pattern. We estimate the critical binding number of these droplets and show that their value is experimentally accessible. We report an approximate energy functional in order to ease the evaluation of the Lee-Huang-Yang correction in practical terms.
