Tensor Catalyzed Decoherence of Primordial Scalar Fluctuations
C. P. Burgess, D. Dineen, R. Holman +1
We provide the first complete calculation of the leading contribution to the decoherence of primordial fluctuations in the scalar part of the metric fluctuations within simplest, s…
Inflationary Decoherence from the Gravitational Floor
C. P. Burgess, R. Holman, Greg Kaplanek
The paper computes the decoherence rate of primordial quantum fluctuations during inflation using only the minimal gravitational interactions required by the model, establishing a…
Quantum Stochastic Inflation
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We formulate stochastic inflation in an open quantum system framework. The field coarse-grained in a patch of fixed physical size, and the total momentum of that patch, form a cano…
Schwinger-Keldysh Path Integral for Gauge theories
Greg Kaplanek, Maria Mylova, Andrew J. Tolley
We develop the Schwinger-Keldysh path-integral formalism for open non-Abelian gauge theories that are gauge-fixed via the BRST method in covariant gauges. We focus on generic initi…
Gauging Open EFTs from the top down
Greg Kaplanek, Maria Mylova, Andrew J. Tolley
We present explicit top-down calculations of Open EFTs for gauged degrees of freedom with a focus on the effects of gauge fixing. Starting from the in-in contour with two copies of…
Cosmic Lockdown: When Decoherence Saves the Universe from Tunneling
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We investigate how quantum decoherence influences the tunneling dynamics of quantum fields in cosmological spacetimes. Specifically, we study a scalar field in an asymmetric double…
