The underlying reasons for the difficulty of unitarily implementing the whole conformal group $SO(4,2)$ in a massless Quantum Field Theory (QFT) are investigated in this paper. Firstly, we demonstrate that the singular action of the subgroup of speci

Dynamics on SL(2,R)tilde-(X)U(1)

Autor: J. M. Cervero, J. A. de Azcárraga, V. Aldaya, Juan Bisquert

Publikováno v: Journal of Physics A: Mathematical and General. 23:707-720

A complete analysis of the quantum dynamical system defined by the quantum group SL(2,R)tilde-(X)U(1) is made. This quantum group, which is primarily related to the relativistic harmonic oscillator, is also shown to provide the quantum dynamics of a

Simple model for a quantum wire III. Transmission of finite samples with correlated disorder

Autor: A. Rodriguez, J. M. Cervero

The effect of a continuous model of correlations upon one-dimensional finite disordered quantum wires modeled by an array of delta-potentials, is analyzed. Although the model proposed is not able to include new truly extended states in the spectrum,

Induced-gravity and higher-curvature terms: Classical solutions

Autor: J. M. Cervero

Publikováno v: Lettere al Nuovo Cimento. 39:125-129

We find nontrivial classical solutions of the field equations derived from an action including higher-curvature terms (R2 andRμv2) in the framework of the induced-gravity approach. The Weyl-Eddington action emerges in a natural way as a unique candi
