I work on a range of problems in quantum many-body physics and quantum information science. One focus of my research is the definition of nonequilibrium phases of matter, where the usual notions of a parent Hamiltonian and spectral gap no longer apply. Through the broader program of the many-body physics of information, I aim to define and classify information-theoretic phases that arise in open quantum systems. More broadly, I am interested in nontrivial dynamics itself, including Lindbladian evolution and quantum cellular automata, where the dynamical process can define a phase of matter that robustly protects information against small perturbations.
