Title: Entanglement in quantum Lifshitz theories

Abstract: In this talk, I will discuss entanglement in quantum Lifshitz theories. These are free (scalar) field theories with anisotropic (Lifshitz) scaling symmetry between space and time. Being closely related to CFTs, they provide simple models for non-relativistic critical theories where entanglement calculations can be performed analytically. I will first review how the entanglement entropy can be calculated in quantum Lifshitz theories. I will then introduce the logarithmic negativity (suitable to characterising quantum entanglement for mixed states), outline its computation in such theories and discuss the results.
