Description
n the initial part of the talk I will review the generalised
quantum Lifshitz models, that is free field theories with
Lifshitz scaling symmetry which extend the (2+1)-dimensional
quantum Lifshitz model to higher dimension. As in the lower
dimensional case the ground state wave functional is
invariant under spatial conformal symmetries, whenever the
dynamical critical exponent is equal to the number of
spatial dimensions.
Thanks to this feature, they provide us with simple models
for non-relativistic critical theories, suitable to
investigate the scaling properties of entanglement entropy.
I will then outline the computation of the sub-leading
universal terms in the entanglement entropy for spherical
entangling hyper-surfaces in these theories, and discuss the
results.
