Modulated Reheating and Large Non-Gaussianity in String Cosmology
M. Cicoli, G. Tasinato, I. Zavala +2
A generic feature of the known string inflationary models is that the same physics that makes the inflaton lighter than the Hubble scale during inflation often also makes other sca…
Saltatory de Sitter String Vacua
C. Escoda, M. Gomez-Reino, F. Quevedo
We extend a recent scenario of Kachru, Kallosh, Linde and Trivedi to fix the string moduli fields by using a combination of fluxes and non-perturbative superpotentials, leading to…
Branonium
C. P. Burgess, P. Martineau, F. Quevedo +1
We study the bound states of brane/antibrane systems by examining the motion of a probe antibrane moving in the background fields of N source branes. The classical system resembles…
Nonabelian Bosonization as Duality
C. P. Burgess, F. Quevedo
Applying the techniques of nonabelian duality to a system of Majorana fermions in 1+1 dimensions we obtain the level-one Wess-Zumino-Witten model as the dual theory. This makes non…
The Linear Multiplet and Quantum 4-D String Effective Actions
J. -P. Derendinger, F. Quevedo, M. Quiros
In 4-D heterotic superstrings, the dilaton and antisymmetric tensor fields belong to a linear N=1 supersymmetric multiplet L. We study the lagrangian describing the coupling of one…
Bosonization as Duality
C. P. Burgess, F. Quevedo
We show that bosonization in two dimensions can be derived as a special case of the duality transformations that have recently been used to good effect in string theory. This allow…
