Research Interests

I am interested in how tensor networks capture aspects (e.g. symmetries) of continuum physics in lattice models considered as regularizations of quantum field theories. I have worked on Matrix Product State simulations of field theories, and have more recently investigated the emergence of conformal symmetry in critical spin chains. Understanding the latter can reveal connections between entanglement and geometry which may be relevant to the AdS/CFT correspondance.
