Unconventional Phases and Phases Transitions in Condensed Matter Theory
内容： We will start with a review of phases and phases transitions beyond the classic Landau's paradigm. Then we will study the phase diagram of the Hubbard model on the honeycomb lattice. Based on r...

Quantum Criticality and Density Correlations in Two-Dimensional Quantum Gases
内容： The collective behavior of a many-body system near a continuous phase transition is insensitive to the details of its microscopic physics. Characteristic features near the phase transition, cal...

Quantum Monte Carlo Studies of Correlated Electrons on Honeycomb Structures
内容： At sufficiently low temperatures, condensed-matter systems tend to develop order. An notable exception to this behavior is quantum spin-liquids, where fluctuations prevent transition to an orde...

Fractional quantum Hall effect in the absence of Landau levels
内容： It has been well-known that topological phenomena with fractional excitations, i.e., the fractional quantum Hall effect (FQHE) will emerge when electrons move in Landau levels. In this talk, I ...
