Gluon Saturation and Black Hole Criticality
L. Alvarez-Gaume, C. Gomez, A. Sabio Vera +2
We discuss the recent proposal in hep-th/0611312 where it was shown that the critical anomalous dimension associated to the onset of non-linear effects in the high energy limit of…
Constructing networks of defects with scalar fields
V. I. Afonso, D. Bazeia, M. A. Gonzalez Leon +2
We propose a new way to build networks of defects. The idea takes advantage of the deformation procedure recently employed to describe defect structures, which we use to construct…
One-loop fluctuations of semi-local self-dual vortices
A. Alonso Izquierdo, W. Garcia Fuertes, M. de la Torre Mayado +1
Mass shifts induced by one-loop fluctuations of semi-local self-dual vortices are computed. The procedure is based on canonical quantization and heat kernel/ zeta function regulari…
A Class of Partially Solvable Two-Dimensional Quantum Models with Periodic Potentials
M. V. Ioffe, J. Mateos Guilarte, P. A. Valinevich
The supersymmetrical approach is used to analyse a class of two-dimensional quantum systems with periodic potentials. In particular, the method of SUSY-separation of variables allo…
One loop corrections to the mass of self-dual semi-local planar topological solitons
A. Alonso Izquierdo, W. Garcia Fuertes, M. de la Torre Mayado +1
A formula is derived that allows the computation of one-loop mass shifts for self-dual semilocal topological solitons. These extended objects, which in three spatial dimensions are…
Lorentzian and signature changing branes
Marc Mars, José M. M. Senovilla, Raül Vera
General hypersurface layers are considered in order to describe brane-worlds and shell cosmologies. No restriction is placed on the causal character of the hypersurface which may t…
