We are interested in the theory of quantum matter. Broadly speaking, this refers to matter in which quantum entanglement between many particles leads to unexpected emergent phenomena, such as unconventional magnetism, superconductivity and topological states. A recent focus has been to understand what types of universal phenomena can emerge in the dynamics of quantum systems, when they are driven strongly out of equilibrium.

In a recent example, we apply approaches of many-body physics and statistical mechanics to understand the collective dynamical behavior of the sort of quantum circuits that make up quantum computers. The unique interplay of unitary gates, entanglement, measurement and noise gives rise to new intriguing types of phase transitions that are pertinent to the circuit's performance as a platform for quantum information processing.

Our work draws from a broad array of theoretical and numerical approaches including field theory, the renormalization group, tensor network calculations (both analytic and numerical) and ideas from quantum information theory.
