My research focuses on understanding many-body physics of strongly coupled
Prior to coming to JILA I worked on a variety of topics in theoretical
condensed matter and material physics, including:
* Exotic states in frustrated magnetic insulators;
* Unconventional superconductivity in strongly repulsive systems;
* Multiferroic materials;
* Kondo physics in heavy-electron systems and topological insulators.
Being at JILA (as a part of the Center for Theory of Quantum Matter) provides a
great opportunity for me to work at the interface between condensed matter and atomic
physics. Indeed, recent studies (done here at JILA) of ultracold ensembles of
alkaline earth atoms, such as strontium or ytterbium, showed that it is
possible to engineer and control such paradigmatic condensed matter systems as
the SU(N) magnets (relevant in the context of high-temperature and
heavy-fermion superconductors) or Kugel-Khomskii-type models (important for
multi-orbital perovskite materials).
I am involved in these projects trying to understand properties of the above
models and propose cold-atom experiments that can also shed light on the
physics of real correlated materials.
After completing my Ph. D. at MIT, I joined Ana Maria Rey’s group in September 2014. I spent part of my Ph.D. working on developing Quantum Monte Carlo (QMC) methods to study dipolar bosonic mixtures in optical lattices. Additionally I developed models for anomalous heating in ion traps, studied the universality of three-body bound states in a mass imbalanced systems, and used three-body bound states to engineer novel many-body Hamiltonians in optical lattices.
I am interested in using ultra-cold atoms or trapped ion systems to simulate condensed matter models and understand exotic quantum phases of matter. To this end I develop tools, such as QMC algorithms, to characterize the equilibrium behavior and non-equilibrium dynamics of the realized systems.
Graduate Students - Alumni
I received my B.S. from Nanjing University in China, and M.S. from the Institute of Theoretical Physics, Chinese Academy of Science. I joined Ana's group as a graduate student in the Fall of 2008. My research interests are the behavior of atoms in optical lattice potentials; for example, new phases and exotic fractal behavior of polarized fermions in bichromatic optical lattices. I am also interested in quantum optics issues, such as the interaction between atoms and a quantized laser field.
I am a graduate student at the University of Colorado Boulder. My current research interests involve ultracold gases of atoms and molecules, and especially the many-body physics of systems with long-range anisotropic dipole-dipole interactions; for example, the non-equilibrium dynamics of ultracold polar molecules and quantum magnetism in an optical lattice.
