My research interests

My research interests include order, phase transitions and quantum correlations in non-equilibrium many-body quantum systems, and phase space methods for simulating driven-dissipative many-body quantum systems, such as the positive-P and truncated Wigner methods.  I have applied these methods to problems relevant to polaritons in semiconductor microcavities including polariton micropillar lattices (via the driven-dissipative Bose-Hubbard model).  Recently, I have also begun work on adapting the positive-P method to systems with coupled bosons and qubits, which may be relevant for investigating problems in the context of circuit QED.
