Our research focuses on two areas, the many body physics of ultracold quantum gases, and
quantum transport in nano-scale devices. It is supported by
Quadrupolar Fermi gas
What are the many-body phases of fermions with quadrupole-quadrupole interaction?
Our exact calculation in the weak-coupling limit reveals.
Phys. Rev. Lett. 110, 155301 (2013)
A topological ladder
On a two-leg ladder, the orbital hopping pattern of fermions leads to a
topological insulating phase. Nature Communications 4, 1523 (2013).
New phase of matter: Bond order solid
Interacting fermions with dipole moments form solids with periodic modulations of bonds, rather than density.
Phys. Rev. Lett. 108, 145301 (2012).
Nearly flat dispersion
The group velocity of quasiparticles
slows down from "speed of light" to a snail pace of almost zero in a hybrid structure of
superconductor and topological insulator.

Hidden topology
Fingerprint of quantum Hall insulators hiding in time-of-flight images. Phys. Rev. A 84, 063629(2011)
