“…where q = p y / defines the quasimomentum,Î is the identity matrix, andŜ x,y,z are the Pauli matrices for spin-1 particles. Unlike the nominal SO-coupling term qŜ z already discussed in Raman-dressed spin-1 atoms [42,43], the SO coupling we realize here is of the form qŜ 2 z , acting as an effective momentum-dependent quadratic Zeeman shift, a coupling between the spin tensor and linear momentum. This same term was recently proposed by Luo et al in a spin-1 atom by introducing an extra Raman laser [44].…”

An experimental proposal for realizing spin-orbit (SO) coupling of pseudospin-1 in the ground manifold 1 Σ(υ = 0) of (bosonic) bialkali polar molecules is presented. The three spin components are composed of the ground rotational state and two substates from the first excited rotational level. Using hyperfine resolved Raman processes through two select excited states resonantly coupled by a microwave, an effective coupling between the spin tensor and linear momentum is realized. The properties of Bose-Einstein condensates for such SO-coupled molecules exhibiting dipolar interactions are further explored. In addition to the SO-coupling-induced stripe structures, the singly and doubly quantized vortex phases are found to appear, implicating exciting opportunities for exploring novel quantum physics using SO-coupled rotating polar molecules with dipolar interactions.

“…We find that the analytic energy (20) is smaller than energy (16). Due to the variational nature of the analytic calculation, energy (20) is closer to the exact energy and hence the secant hyperbolic form (21) of the wave function is a better approximation to the exact solution than the Gaussian form (17).…”

We demonstrate the formation of multi-peak three-component stationary stripe vector solitons in a quasi-onedimensional spin-orbit-coupled hyper-fine spin F = 1 polar Bose-Einstein condensate. The present investigation is carried out through a numerical solution by imaginary-time propagation and an analytic variational approximation of the underlying mean-field Gross-Pitaevskii equation. Simple analytic results for energy and component densities were found to be in excellent agreement with the numerical results for solitons with more than 100 pronounced maxima and minima. The vector solitons are one of the two types: dark-bright-dark or bright-dark-bright. In the former a maximum density in component F z = 0 at the center is accompanied by a zero in components F z = ±1. The opposite happens in the latter case. The vector solitons are demonstrated to be mobile and dynamically stable. The collision between two such vector solitons is found to be quasi elastic at large velocities with the conservation of total density of each vector soliton. However, at very small velocity, the collision is inelastic with a destruction of the initial vector solitons. It is possible to observe and study the predicted SO-coupled vector solitons in a laboratory.

We study the Bloch oscillation dynamics of a spin-orbit-coupled cold atomic gas trapped inside a one-dimensioanl optical lattice. The eigenspectra of the system is identified as two interpenetrating Wannier-Stark ladder. Based on that, we carefully analyzed the Bloch oscillation dynamics and found out that intraladder coupling between neighboring rungs of Wannier-Stark ladder give rise to ordinary Bloch oscillation while interladder coupling lead to small amplitude high frequency oscillation superimposed on it. Specifically spin-orbit interaction breaks Galilean invariance, which can be reflected by out-of-phase oscillation of the two spin components in the accelerated frame. The possibility of generating spin current in this system are also explored.
