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
Some calculable contributions to entanglement entropy.
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 interactions like gravity are taken into account.
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,…
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

- 17 March 2010
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…
Entanglement entropy in scalar field theory
- M. Hertzberg
- 20 September 2012
Understanding the dependence of entanglement entropy on the renormalized mass in quantum field theories can provide insight into phenomena such as quantum phase transitions, since the mass varies in…
