Half-quantized Transport in Axion Insulators
We propose that half-quantized helical hinge currents manifest as the fingerprint of the axion insulator. These helical hinge currents microscopically originate from the lateral Goos-Hänchen (GH) shif...

Explore dark matter by gravitational wave and radio signals
The LIGO-Virgo Collaboration has so far detected more than 100 black holes, whose mass distribution appears to have a peak at ∼ 30M☉ and two tails on the ends. By assuming that they all have a primo...

Quantum droplet in ultracold gases
Quantum droplet describes a self-bound object that is stabilized by quantum effect. It has a long research history ever since the Kerson Huang's theoretical model in late 1950s and the intensive study...

Excited State Ultrafast Dynamics of Superconductors and Topological Materials
I will first address our ultrafast spectroscopy investigations of iron-based high temperature superconductors, showing that there is a ubiquitous positive correlation between the electron-phonon coupl...
