On the consistency of universally non-minimally coupled theories
Ismael Ayuso, Jose Beltran Jimenez, Alvaro de la Cruz Dombriz
We discuss the consistency of a recently proposed class of theories described by an arbitrary function of the Ricci scalar, the trace of the energy-momentum tensor and the contract…
Spinning strings in AdS_3 x S^3 with NS-NS flux
Rafael Hernandez, Juan Miguel Nieto
The sigma model describing closed strings rotating in AdS_3 x S^3 is known to reduce to the one-dimensional Neumann-Rosochatius integrable system. In this article we show that clos…
Supersymmetric Chern-Simons-matter theory and phase transitions
Jorge G. Russo, Guillermo A. Silva, Miguel Tierz
We study supersymmetric Chern-Simons with fundamental and antifundamental chiral multiplets of mass in the complete parameter space spa…
Conformal and non Conformal Dilaton Gravity
Enrique Alvarez, Mario Herrero-Valea, C. P. Martín
The quantum dynamics of the gravitational field non-minimally coupled to an (also dynamical) scalar field is studied in the {\em broken phase}. For a particular value of the coupli…
