@article{Zhang2012MacroscopicKT, title={Macroscopic Klein tunneling in spin-orbit-coupled Bose-Einstein condensates}, author={Dan-Wei Zhang and Zheng‐Yuan Xue and Hui Yan and Zhi De Wang and Shi-Liang Zhu}, journal={Physical Review A}, year={2012}, volume={85} }

We propose an experimental scheme to detect macroscopic Klein tunneling with spin-orbit coupled Bose-Einstein condensates (BECs). We show that a nonlinear Dirac equation with tunable parameters can be realized with such BECs. %in a simple configuration to generate the artificial spin-orbit coupling. Through numerical calculations, we demonstrate that macroscopic Klein tunneling can be clearly detected under realistic conditions. Macroscopic quantum coherence in such relativistic tunneling is…
