Conformally covariant quantization of Maxwell field in de Sitter space (2009)
Faci, S., Huguet, E., Queva, J., Renaud, J.
In this article, we quantize the Maxwell ("massless spin one") de Sitter field in a conformally invariant gauge. This quantization is invariant under the SO$_0(2,4)$ group and consequently under the...
Infinite quantum well: a coherent state approach (2008)
A new family of 2-component vector-valued coherent states for the quantum particle motion in an infinite square well potential is presented. They allow a consistent quantization of the classical...
Huguet, E., Queva, J., Renaud, J.
In this article, we clarify the link between the conformal (i.e. Weyl) correspondence from the Minkowski space to the de Sitter space and the conformal (i.e. SO(2,$d$)) invariance of the conformal...
Conformally related massless fields in dS, AdS and Minkowski spaces (2007)
Huguet, E., Queva, J., Renaud, J.
In this paper we write down the equation for a scalar conformally coupled field simultaneously for de Sitter (dS), anti-de Sitter (AdS), and Minkowski spacetimes in d dimensions. The curvature...
A toy model for fake inflation (2006)
Novello, M., Huguet, E., Queva, J.
Discontinuities in non linear field theories propagate through null geodesics in an effective metric that depends on its dynamics and on the background geometry. Once information of the geometry of...
