In-in formalism for the entropy of quantum fields in curved spacetimes
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 …

Gravity as a mesoscopic system
We employ a probabilistic mesoscopic description to draw conceptual and quantitative
analogies between Brownian motion and late-time fluctuations of thermal correlation …
