In the presence of a laser-induced spin-orbit coupling an interacting ultra cold spinor Bose-Einstein condensate may acquire a quasi-relativistic character described by a non-linear Dirac-like equation. We show that as a result of the spin-orbit coupling and the non-linearity the condensate may become self-trapped, resembling the so-called chiral confinement, previously studied in the context of the massive Thirring model. We first consider 1D geometries where the self-confined condensates present an intriguing sinusoidal dependence on the inter-particle interactions. We further show that multidimensional chiral-confinement is also possible under appropriate feasible laser arrangements, and discuss the properties of 2D and 3D condensates, which differ significantly from the 1D case.PACS numbers: 42.50.

Interestingly, seminal experiments on optically created gauge fields have been recently reported [6]. Artificial electromagnetism has attracted a growing attention in recent years, partially due to the possibility of achieving nonAbelian gauge fields [4,5], which establish fascinating links between cold gases and high-energy physics [4,7,8]. A striking example is given by the possibility of inducing quasi-relativistic physics in cold atoms despite the extremely low velocities involved [9]. In particular, under proper conditions cold atoms may experience an effective spin-orbit coupling, which leads to a Dirac cone in the dispersion [10], resembling the case of yet another paradigm of modern physics, namely graphene [11,12]. Similar phenomena are expected in cold atoms and graphene including Veselago lensing [9,13,14].Interparticle interactions lead to inherent nonlinearities in Bose-Einstein condensates (BECs). At sufficiently low temperatures the BEC physics is described by a nonlinear Schödinger equation similar to that found in nonlinear optics [1]. Resemblances between both fields have been successfully explored in recent years, most remarkably in what concerns the physics of solitons [15,16,17,18,19], for which nonlinearity and dispersion compensate leading to a non-dispersing solution. Nonlinearity plays also an important role in high-energy physics. Indeed, non-linear Dirac equations (NLDEs), and more generally non-linear spinor fields, have been studied extensively, starting with the pioneering works of Ivanenko [20], Weyl [21], and Heisenberg [22]. These equations may present also localized solutions [23,24].In this Letter we explore the nonlinear physics of a multicomponent BEC (also called spinor BEC [25]) in the presence of an optically-induced spin-orbit coupling. In the low-momentum limit, the spinor BEC may be described by a particular type of two-component NLDE. We show that for the case of attractive interactions, the condensate may become self-trapped, rese...
