The realization of synthetic spin-orbit coupling represents one of the most important achievements in the physics of ultracold atomic gases. In this talk I shall illustrate some of my theoretical predictions about the properties of two-component Bose-Einstein condensates with equal-weighted Rashba and Dresselhaus spin-orbit couplings. Their phase diagram includes different structures, such as a spin-polarized plane-wave phase, and a stripe phase featuring density modulations. Because of the simultaneous presence of superfluidity and of a crystalline structure, the stripe phase exhibits the long-sought phenomenon of supersolidity. Several relevant features of this configurations, recently observed in an experiment by Ketterle’s group at MIT, will be discussed.
