# Emergence of topological and strongly correlated ground states in trapped Rashba spin-orbit-coupled Bose gases

@article{Ramachandhran2013EmergenceOT, title={Emergence of topological and strongly correlated ground states in trapped Rashba spin-orbit-coupled Bose gases}, author={B. Ramachandhran and Hui Hu and Han Pu}, journal={Physical Review A}, year={2013}, volume={87}, pages={033627} }

We theoretically study an interacting few-body system of Rashba spin-orbit coupled two-component Bose gases confined in a harmonic trapping potential. We solve the interacting Hamiltonian at large Rashba coupling strengths using Exact Diagonalization scheme, and obtain the ground state phase diagram for a range of interatomic interactions and particle numbers. At small particle numbers, we observe that the bosons condense to an array of topological states with n+1/2 quantum angular momentum…

This paper investigates EIT in a SO-coupled BEC, where not only is the transparency existing, but the real and imaginary parts of the susceptibility have an additional red frequency shift, which is linearly proportional to the strength of the SO coupling.
