Research Experience

Condensed Matter

Aug-Nov, 2012 Novel London moments in rapidly rotating topological insulators

  • I devised a universal and quantum mechanical formalism of non-inertial effects in rotating crystals, consistent with London moment in superconductors and Barnett's effects.

  • I showed that rotation-induced pseudo-gauge field is affiliated to charge U(1) gauge rather than being an independent "artificial gauge field."

  • In contrast to trivial crystals, I predicted theoretically two novel types of moments in rotating topological insulators (TI) in the presence of a auxiliary magnetic field.

  • When the auxiliary field is applied parallel or radially perpendicular to the rotation axis, one will observe a quadratic magnetic moment and an electric moment respectively.

  • I suggested a "solenoid" structure and lock-in measurement to improve detectability and precision.

  • I also pointed out that the experiments will shed light on interactions inside a TI and clarify some controversies over rotating crystals.

Cold Atoms

Aug, 2012 Effects of Rashba-Dresselhaus competition in 2D two-component spinor BEC

  • I combined the two spin-orbit coupling strengths into a single complex parameter with argument α characterizing the mixing.

  • In the free particle model, I demonstrated explicitly how the ground state degeneracy evolves as a function of α;

  • Effects of Zeeman term and parity breaking term on dispersion relation were also studied.
