TRAPPED QUINTESSENTIAL INFLATION FROM FLUX COMPACTIFICATIONS [PDF]

open access: greenThe Identification of Dark Matter, 2007
Quintessential inflation is studied using a string modulus as the inflaton - quintessence field. It is assumed that the modulus crosses an enhanced symmetry point (ESP) in field space. Particle production at the ESP temporarily traps the modulus resulting in a period of inflation.

Exceptional flux compactifications [PDF]

open access: hybridJournal of High Energy Physics, 2012
AbstractWe consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gaugedD= 4 supergravity. This enables one to investigate the critical points, mass spectra and gauge groups of such backgrounds.

Warped flux compactification and brane gravity [PDF]

open access: greenJournal of Cosmology and Astroparticle Physics, 2005
We find a simple exact solution of 6-dimensional braneworld which captures some essential features of warped flux compactification, including a warped geometry, compactification, a magnetic flux, and one or two 3-brane(s). In this setup we analyze how the Hubble expansion rate on each brane changes when the brane tension changes.

Flux compactification [PDF]

open access: greenReviews of Modern Physics, 2007
We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics.

Type IIA Flux Compactifications [PDF]

open access: greenNuclear Physics B - Proceedings Supplements, 2009

Nonlinear dynamics of flux compactification

open access: yesJournal of High Energy Physics, 2021
We study the nonlinear evolution of unstable flux compactifications, applying numerical relativity techniques to solve the Einstein equations in D dimensions coupled to a q-form field and positive cosmological constant. We show that initially homogeneous

Lobotomy of flux compactifications [PDF]

open access: yesJournal of High Energy Physics, 2014
We provide the dictionary between four-dimensional gauged supergravity and type II compactifications on $\mathbb{T}^6$ with metric and gauge fluxes in the absence of supersymmetry breaking sources, such as branes and orientifold planes. Secondly, we prove that there is a unique isotropic compactification allowing for critical points.

F-theory flux vacua and attractor equations

open access: yesJournal of High Energy Physics, 2020
We examine the vacuum structure of 4D effective theories of moduli fields in spacetime compactifications with quantized background fluxes. Imposing the no-scale structure for the volume deformations, we numerically investigate the distributions of flux ...
