The talk focusses on the computation and analysis of entanglement measures in generalised quantum Lifshitz models. These are free field theories with Lifshitz scaling symmetry which extend the (2+1)-dimensional quantum Lifshitz model to higher dimension, and provide us with simple models for non-relativistic critical theories. I will introduce various entanglement measures, such as entanglement entropy and logarithmic negativity (suitable to characterising quantum entanglement for pure and mixed states respectively), outline their computation in generalised quantum Lifshitz theories, and discuss the results.
