Entanglement Entropy of Excited States in the Quantum Lifshitz Model
J. Angel-Ramelli
In this work we calculate the entanglement entropy of certain excited states of the quantum Lifshitz model. The quantum Lifshitz model is a 2 + 1-dimensional bosonic quantum field…
Logarithmic Negativity in Quantum Lifshitz Theories
J. Angel-Ramelli, C. Berthiere, V. Giangreco M. Puletti +1
We investigate quantum entanglement in a non-relativistic critical system by calculating the logarithmic negativity of a class of mixed states in the quantum Lifshitz model in one…
Entanglement Entropy in Generalised Quantum Lifshitz Models
J. Angel-Ramelli, V. Giangreco M. Puletti, L. Thorlacius
We compute universal finite corrections to entanglement entropy for generalised quantum Lifshitz models in arbitrary odd spacetime dimensions. These are generalised free field theo…
