Entanglement masquerading in the CMB
Arsalan Adil, Andreas Albrecht, Rose Baunach +3
The simplest single-field inflation models capture all the relevant contributions to the patterns in the Cosmic Microwave Background (CMB) observed today. A key assumption in these…
Minimal decoherence from inflation
C. P. Burgess, R. Holman, Greg Kaplanek +2
We compute the rate with which super-Hubble cosmological fluctuations are decohered during inflation, by their gravitational interactions with unobserved shorter-wavelength scalar…
Loop corrections in Minkowski spacetime away from equilibrium. Part II. Finite-time results
Spasen Chaykov, Nishant Agarwal, Sina Bahrami +1
Loop corrections to finite-time correlation functions in quantum field theories away from equilibrium can be calculated using the in-in path integral approach. In this paper, we ca…
Loop corrections in Minkowski spacetime away from equilibrium. Part I. Late-time resummations
Spasen Chaykov, Nishant Agarwal, Sina Bahrami +1
Loop corrections to unequal-time correlation functions in Minkowski spacetime exhibit secular growth due to a breakdown of time-dependent perturbation theory. This is analogous to…
Quantum Hotspots: Mean Fields, Open EFTs, Nonlocality and Decoherence Near Black Holes
C. P. Burgess, R. Holman, G. Kaplanek
Effective theories describing black hole exteriors resemble open quantum systems inasmuch as many unmeasurable degrees of freedom beyond the horizon interact with those we can see.…
Qubit Heating Near a Hotspot
G. Kaplanek, C. P. Burgess, R. Holman
Effective theories describing black hole exteriors contain many open-system features due to the large number of gapless degrees of freedom that lie beyond reach across the horizon.…
