Artificial Gauge Field and Quantum Spin Hall States in a Conventional Two-dimensional Electron Gas
Likun Shi, Wenkai Lou, F. Cheng +3
Based on the Born-Oppemheimer approximation, we divide total electron Hamiltonian in a spinorbit coupled system into slow orbital motion and fast interband transition process. We f…

Bose-Einstein condensation on an atom chip
Bo Yan, Feng Cheng, Min Ke +3
We report an experiment of creating Bose-Einstein condensate (BEC) on an atom chip. The chip based Z-wire current and a homogeneous bias magnetic field create a tight magnetic trap…
