The field-to-particle transition problem
Jeronimo Cortez, Leonardo Patino, Hernando Quevedo
We formulate in an intuitive manner several conceptual aspects of the field-to-particle transition problem which intends to extract physical properties of elementary particles from…
Reply to the Comment ``On the thermodynamics of inhomogeneous perfect fluid mixtures''
Hernando Quevedo, Ruben D. Zarate
We show that the analysis presented in a recent comment by Coll and Ferrando \cite{comment} (qr-qc/0312058) is based on the erroneous assumption that the chemical potential and fra…
The Big Bang in Gowdy Cosmological Models
Hernando Quevedo
We establish a formal relationship between stationary axisymmetric spacetimes and Gowdy cosmological models which allows us to derive several preliminary results about the ge…
On the Energy of Rotating Gravitational Waves
Bahram Mashhoon, James C. McClune, Enrique Chavez +1
A class of solutions of the gravitational field equations describing vacuum spacetimes outside rotating cylindrical sources is presented. A subclass of these solutions corresponds…
Quantization of 2+1 Gravity on the Torus
A. Criscuolo, H. Quevedo, H. Waelbroeck
We use the polygon representation of 2+1--dimensional gravity to explicitly carry out the canonical quantization of a universe with the topology of a torus. The mapping-class-invar…
Stationary Axisymmetric Fields as Two-Dimensional Geodesics
D. Nunez, H. Quevedo
Einstein's equations for stationary axisymmetric fields are reformulated as the equations for affine geodesics in a two--dimensional space. The affine collineations of this space a…
