Entangled states as a probe of early universe history: a Higgs case study
Rose Baunach
I explore whether distinguishing features of phase transitions and/or the inflationary energy scale can be imprinted on cosmological observables due to entanglement during inflatio…
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…
Adapted Caldeira-Leggett Model
Andreas Albrecht, Rose Baunach, Andrew Arrasmith
We preset a variant of the Caldeira-Leggett (CL) model of a harmonic oscillator coupled to an environment. The CL model is a standard tool for studying the physics of decoherence.…
Copycat process in the early stages of einselection
Rose Baunach, Andreas Albrecht, Andrew Arrasmith
We identify and describe unique early time behavior of a quantum system initially in a superposition, interacting with its environment. This behavior -- the copycat process -- occu…
Einselection, Equilibrium and Cosmology
Andreas Albrecht, Rose Baunach, Andrew Arrasmith
Our observed Universe has a very strong arrow of time rooted in its low entropy starting point. This low entropy start can be related to various "tuning puzzles" about the early st…
Does Planck Actually "See" the Bunch-Davies State?
Rose Baunach, Nadia Bolis, R. Holman +2
To what extent can the Planck satellite observations be interpreted as confirmation of the quantum part of the inflationary paradigm? Has it "seen" the Bunch-Davies state? We compa…
