Dissipation due to fermions in inflaton equations of motion
Javier Moreno Almeida, Ian D. Lawrie
According to quantum field theory, the inflaton equation of motion does not have the local form that is generally assumed for cosmological purposes. In particular, earlier investig…

Witnessing Macroscopic Entanglement in a Staggered Magnetic Field
Jenny Hide, Wonmin Son, Ian Lawrie +1
We investigate macroscopic entanglement in an infinite XX spin-1/2 chain with staggered magnetic field, B_l=B+e^{-iπl}b. Using single-site entropy and by constructing an entangleme…

Nonequilibrium quantum dynamics of phase transitions in an expanding universe
Ian D Lawrie
I summarize the derivation of a set of Feynman rules appropriate for the perturbative description of the nonequilibrium dynamics of the symmetry-breaking phase transition in …
