Exciton-polaritons are a coherent electron-hole-photon (e-h-p) system where condensation has been observed in semiconductor microcavities. In contrast to equilibrium Bose-Einstein condensation (BEC) for long lifetime systems, polariton condensates ha

We review high-orbital exciton-polariton condensation experiments in various two-dimensional lattices. The dynamical nature of exciton-polaritons spontaneously forms condensates at non-zero momentum, resulting from the competition between the finite

We experimentally studied the transient properties of polariton relaxation dynamics through the oscillatory behavior of an exciton-polariton condensate. The oscillations show characteristic pump po...

We explore the exciton-polariton condensation in the two degenerate orbital states. In the honeycomb lattice potential, at the third band we have two degenerate vortex-antivortex lattice states at the inequivalent K and K'-points. We have observed en

Microcavity exciton-polaritons are quantum quasi-particles arising from the strong light-matter coupling. They have exhibited rich quantum dynamics rooted from bosonic nature and inherent non-equilibrium condition. Dynamical condensation in microcavi

We explore two degenerate high-orbital exciton-polariton condensates in a honeycomb lattice. We measure the order parameter of the condensates, identifying the vortex-antivortex lattice order. We also study the intensity correlation relation between

Dirac particles, massless relativistic entities, obey linear energy dispersions and hold important implication in particle physics. Recent discovery of Dirac fermions in condensed matter systems including graphene and topological insulators raises gr

Interface Between Quantum Information and Statistical Physics.
We propose a device for studying the Fermi-Hubbard model with long-range Coulomb interactions using an array of quantum dots defined in a semiconductor two-dimensional electron gas system. Bands with energies above the lowest energy band are used to
