Nonlinear perturbations of cosmological scalar fields with non-standard kinetic terms

Sebastien Renaux-Petel, Gianmassimo Tasinato

We adopt a covariant formalism to derive exact evolution equations for nonlinear perturbations, in a universe dominated by two scalar fields. These scalar fields are characterized…

Symmetries of the relativistic two-boson system in external field

Philippe Droz-Vincent

We investigate the survival of symmetries in a relativistic system of two mutually interacting bosons coupled with an external field, when this field is "strongly" translation inva…

Scaling function in AdS/CFT from the O(6) sigma model

Z. Bajnok, J. Balog, B. Basso +2

Asymptotic behavior of the anomalous dimensions of Wilson operators with high spin and twist is governed in planar N=4 SYM theory by the scaling function which coincides at strong…

Dirac Born Infeld (DBI) Cosmic Strings

Eugeny Babichev, Philippe Brax, Chiara Caprini +2

Motivated by brane physics, we consider the non-linear Dirac-Born-Infeld (DBI) extension of the Abelian-Higgs model and study the corresponding cosmic string configurations. The mo…

Stringy Instantons as Strong Dynamics

Antonio Amariti, Luciano Girardello, Alberto Mariotti

We study the relation between stringy instantons and strong dynamics effects in type IIB toric quiver gauge theories. By exploiting the involutive property of Seiberg duality we re…

A study on relativistic lagrangian field theories with non-topological soliton solutions

J. Diaz-Alonso, D. Rubiera-Garcia

We perform a general analysis of the dynamic structure of two classes of relativistic lagrangian field theories exhibiting static spherically symmetric non-topological soliton solu…
