Entangled inflationary quantum states offer an interesting alternative to the standard Bunch-Davies vacuum. While they can be viewed from the point of view of a theory of effective initial states, it has been unclear exactly how such states might be generated. Using a model involving two scalar fields $\Phi,\Sigma$ we show that if {\em both} fields have non-zero time dependent expectation values $\phi,\sigma$ respectively, and if the interaction potential $V(\Phi,\Sigma)$ when evaluated at… 

Entanglement negativity in de Sitter biverse from Stringy Axionic Bell pair: An analysis using Bunch-Davies vacuum

In this work, we study the signatures of quantum entanglement by computing entanglement negativity between two causally unrelated regions in 3 + 1 dimensional global de Sitter space. We investigate a

Does Planck actually “see” the Bunch-Davies state?

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 compare and contrast the

Non-Gaussianity from entanglement during inflation

We compute the bi-spectrum of CMB temperature fluctuations for a state where the metric perturbation ζ is entangled with a spectator scalar field χ. Novel terms in the cubic ζ action coupled to the



Cosmic Inflation: The Most Powerful Microscope in the Universe

How well can we constrain the initial quantum state of metric perturbations sourced during inflation? We exhibit an interesting new class of quantum states that entangle the scalar metric

Cosmological consequences of initial state entanglement

A bstractWe explore the cosmological consequences of having the fluctuations of the inflaton field entangled with those of another scalar, within the context of a toy model consisting of

Entangled scalar and tensor fluctuations during inflation

We show how the choice of an inflationary state that entangles scalar and tensor fluctuations affects the angular two-point correlation functions of the T, E, and B modes of the cosmic microwave

Tensor bounds on the hidden universe

The main result is that one can extract bounds on the hidden field content of the universe from bounds on violations of the consistency relation between the Tensor spectral index and the tensor to scalar ratio, were primordial tensors ever detected.

Quantum entanglement in multi-field inflation

We study the emergence of quantum entanglement in multi-field inflation. In this scenario, the perturbations of one field contribute to the observable curvature perturbation, while multi-field

Quantum cosmic no-hair theorem and inflation

We consider implications of the quantum extension of the inflationary no hair theorem. We show that when the quantum state of inflation is picked to ensure the validity of the EFT of fluctuations, it

Impact of quantum entanglement on spectrum of cosmological fluctuations

We investigate the effect of entanglement between two causally separated open charts in de Sitter space on the spectrum of vacuum fluctuations. We consider a free massive scalar field, and construct

Nonequilibrium evolution of scalar fields in FRW cosmologies.

It is found that a suitably defined nonequilibrium entropy per mode increases linearly with comoving time in a de Sitter cosmology, whereas it is [ital not] a monotonically increasing function in the radiation-dominated case.

A renormalization ansatz based on the DeWitt-Schwinger expansion is proposed, and it is shown that this removes all am biguities previously present in pointsplitting regularization.

Holographic bounds and finite inflation

We compare two holographic arguments that impose especially strong bounds on the amount of inflation. One comes from the de Sitter Equilibrium cosmology and the other from the work of Banks and
