Mainly in the fields of strongly correlated systems and statistical mechanics.
Some recent focus areas include:
- Frustrated magnets and spin liquids.
- Unconventional phase transitions (beyond Landau-Ginzburg-Wilson paradigm).
- Nonequilibrium quantum dynamics and phases.
- Numerical many-body physics (primarily Monte Carlo algorithms).
- Disorder effects in strongly correlated phases and phase transitions.
- Spin systems with constrained Hilbert spaces and lattice gauge theories.
