The effective field theory of cosmological large scale structures
A bstractLarge scale structure surveys will likely become the next leading cosmological probe. In our universe, matter perturbations are large on short distances and small at long scales, i.e.
Inflationary Constraints on Type IIA String Theory
We prove that inflation is forbidden in the most well understood class of semi-realistic type IIA string compactifications: Calabi-Yau compactifications with only standard NS-NS 3-form flux, R-R
CMBPol Mission Concept Study Probing Ination with CMB Polarization
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of ination. We focus on the prospects for using CMB measurements
Running inflation in the Standard Model
Abstract An interacting scalar field with largish coupling to curvature can support a distinctive inflationary universe scenario. Previously this has been discussed for the Standard Model Higgs
Some calculable contributions to entanglement entropy.
TLDR
Finite, calculable contributions to the entanglement entropy are extracted for a scalar field between the interior and exterior of a spatial domain of arbitrary shape by considering parametric dependence on correlation length.
Do dark matter axions form a condensate with long-range correlation?
The authors investigate the formation of Bose-Einstein condensates from axion dark matter, and it is shown that a homogeneous condensate with long range correlations is unstable when
Axion cosmology and the energy scale of inflation
We survey observational constraints on the parameter space of inflation and axions and map out two allowed windows: the classic window and the inflationary anthropic window. The cosmology of the
Quantum radiation of oscillons
Many classical scalar field theories possess remarkable solutions: coherently oscillating, localized clumps, known as oscillons. In many cases, the decay rate of classical small amplitude oscillons
Dark matter axion clump resonance of photons
Recently there has been interest in the physical properties of dark matter axion condensates. Due to gravitational attraction and self-interactions, they can organize into spatial localized clumps,
