Research Interests

Ultracold atoms and molecules, Superfluidity, Superconductivity

There is a unifying theme across multiple fields of physics: if some particles have wave lengths comparable to their average distance, their properties must be described quantum mechanically. These include nuclear physics, as in atomic nuclei and neutron stars, in which the neutrons and/or protons are considered "cold" even at temperatures many orders of magnitude higher than room temperature, a large part of condensed matter / material physics, where electrons are the objects of main interest and are usually quantum degenerate, and the physics of cold atoms and molecules.

I am currently studying the quantum many-body and few-body theory of atoms and molecules (either fermions or bosons) at nanokelvin temperature scales, whose interaction strengths can be experimentally tuned across many orders of magnitude. In the few-body sector, topics include Efimov effect at large scattering length, mixed dimensionality (in the sense that different particles live in different spatial dimensions, and interact with each other), and effective three-body interactions. In the many-body sector, topics include exact relations among various physical observables, physics in one spatial dimension, and new states of matter for future experimental realization. My research area lies at the interface of condensed matter and Atomic, Molecular, and Optical physics. It also has intriguing connections to nuclear physics and particle physics (for instance, the effective three-body interaction is relevant for both cold atoms and mesons).

Another area of current interest is the application of quantum many-body theory to classical systems such as directed polymers. The interaction of the two areas is a two-way road. In the exploration of the classical systems, I got a deeper insight into quantum systems, such as ultracold atomic gases confined in a box trap.

Current students: Shangguo Zhu and Kevin Driscoll.

On a personal note, I am happily married. My wife and I have a daughter born in 2013.
