Measuring the strength of dissipative inflation
L. Herrera, A. Di Prisco, D. Pavon
We comment on recently proposed dissipative inflationary models. It is shown that the strength of the inflationary expansion is related to a specific combination of thermodynamic v…
Knot Invariants from Classical Field Theories
Lorenzo Leal
We consider the Non-Abelian Chern-Simons term coupled to external particles, in a gauge and diffeomorphism invariant form. The classical equations of motion are perturbativelly stu…
Analytical Description of Voids in Majumdar-Papapetrou Spacetimes
Victor Varela
We discuss new Majumdar-Papapetrou solutions for the 3+1 Einstein-Maxwell equations, with charged dust acting as the external source of the fields. The solutions satisfy non-linear…
Aspects of Type 0 String Theory
R. Blumenhagen, A. Font, A. Kumar +1
A construction of compact tachyon-free orientifolds of the non-supersymmetric Type 0B string theory is presented. Moreover, we study effective non-supersymmetric gauge theories ari…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
Non-Supersymmetric Gauge Theories from D-Branes in Type 0 String Theory
Ralph Blumenhagen, Anamaria Font, Dieter Lust
We construct non-supersymmetric four dimensional gauge theories arising as effective theories of D-branes placed on various singularities in Type 0B string theory. We mostly focus…
Soliton structure dynamics in inhomogeneous media
L. E. Guerrero, A. Bellorin, J. A. Gonzalez
We show that soliton interaction with finite-width inhomogeneities can activate a great number of soliton internal modes. We obtain the exact stationary soliton solution in the pre…
Soliton tunneling with sub-barrier kinetic energies
J. A. Gonzalez, A. Bellorin, L. E. Guerrero
We investigate (theoretically and numerically) the dynamics of a soliton moving in an asymmetrical potential well with a finite barrier. For large values of the width of the well,…
Tachyon-free Orientifolds of Type 0B Strings in Various Dimensions
Ralph Blumenhagen, Anamaria Font, Dieter Lust
We construct non-tachyonic, non-supersymmetric orientifolds of Type 0B strings in ten, six and four space-time dimensions. Typically, these models have unitary gauge groups with ch…
Spatiotemporal chaotic dynamics of solitons with internal structure in the presence of finite-width inhomogeneities
L. E. Guerrero, A. Bellorin, J. R. Carbo +1
We present an analytical and numerical study of the Klein-Gordon kink-soliton dynamics in inhomogeneous media. In particular, we study an external field that is almost constant for…
Massive Gauge Axion Fields
P. J. Arias, A. Khoudeir
A gauge invariant formulation for the massive axion is considered. The axion acquires mass through a topological term which couples a (pseudo)scalar and a third rank antisymmetric…
