I am a professor working on condensed matter theory. My current interest is in topological order, which correspond to patterns of longrange entanglement in manybody system.
Understanding patterns of manybody entanglement is related to some modern mathematics. For example, the math framework for 2D longrange entanglements happen to be unitary fusion category theory. For higher dimensions, we may need higher categories. The math framework for shortrange entanglements with symmetry happen to be group cohomology theory of the symmetry group and cobordism theory.
