Thermoalgebras and path integral
(Elsevier, 2009-09)
Using a representation for Lie groups closely associated with thermal problems, we derive the algebraic rules of the real-time formalism for thermal quantum field theories, the so-called thermo-field dynamics (TFD), including ...
Microscopic theory of the Casimir force at thermal equilibrium: Large-separation asymptotics
(2008)
We present an entirely microscopic calculation of the Casimir force f (d) between two metallic plates in the limit of large separation d. The models of metals consist of mobile quantum charges in thermal equilibrium with ...
Entropía de entanglement de agujeros negros en la dualidad AdS/CFT
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - FísicaFacultad de CienciasBogotá,ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2023-04-19)
En esta tesis se estudia un campo escalar sobre un espacio tiempo de Schwarzschild usando los estados de vacío de Boulware y Hartle-Hawking-Israel teniendo en cuenta la interpretación Mukohyama-Israel para tratar de explicar ...
Bekenstein bound in asymptotically free field theory
(2010-08-03)
For spatially bounded free fields, the Bekenstein bound states that the specific entropy satisfies the inequality SE≤2πR, where R stands for the radius of the smallest sphere that circumscribes the system. The validity of ...
Bogoliubov transformation for quantum fields in (Bbb S1)d × Bbb RD−d topology and applications to the Casimir effect
(2009)
A Bogoliubov transformation accounting simultaneously for spatial compactifica-tion and thermal effects is introduced. The fields are described in a ΓDd = Bbb S11 × ... × Bbb S1d × Bbb RD−d topology, and the Bogoliubov ...
Asymptotic boundary conditions and square integrability in the partition function of AdS gravity
(Springer, 2020-06)
There has been renewed interest in the path-integral computation of the partition function of AdS3 gravity, both in the metric and Chern-Simons formulations. The one-loop partition function around Euclidean AdS3 turns out ...
