We study the quantum-droplet state in a three-dimensional (3D) Bose gas in the presence of 1D spin-orbit coupling and Raman coupling,especially the stripe phase with density modulation,by numerically computing the ground state energy including the mean-field energy and Lee Huang Yang correction.In this droplet state,the stripe can exist in a wider range of Raman coupling,compared with the BEC-gas state.More intriguingly,both spin-orbit coupling and Raman coupling strengths can be used to tune the droplet density.
