Query: Field Space Entanglement Entropy, Zero Modes and Lifshitz Models   The field space entanglement entropy of a quantum field theory is obtained by
integrating out a subset of its fields. We study an interacting quantum field
theory consisting of massless scalar fields on a closed compact manifold M. To
this model we associate its Lifshitz dual model. The ground states of both
models are invariant under constant shifts. We interpret this invariance as
gauge symmetry and subject the models to proper gauge fixing. By applying the
heat kernel regularization one can show that the field space entanglement
entropies of the massless scalar field model and of its Lifshitz dual are
agreeing.
