In-in formalism for the entropy of quantum fields in curved spacetimes
T Colas, J Grain, G Kaplanek… - Journal of Cosmology and …, 2024 - iopscience.iop.org
We show how to compute the purity and entanglement entropy for quantum fields in a
systematic perturbative expansion. To that end, we generalize the in-in formalism to non …
