Vacuum polarization in the Schwarzschild black hole with a global monopole
Leonardo G. Barbosa, Victor H. M. Ramos, João Paulo M. Pitelli
We investigate vacuum polarization on the event horizon of a Schwarzschild black hole carrying a global monopole. For a massless scalar field in the Hartle-Hawking state and wi…
Canonical quantization for Equilibrium Thermodynamics
Luis F. Santos, Victor Hugo M. Ramos, Danilo Cius +2
We formulate a canonical quantization of Equilibrium Thermodynamics by applying Dirac's theory of constrained systems. Thermodynamic variables are treated as conjugate pairs of coo…
Invisible extended Unruh-DeWitt detector
Victor Hugo M. Ramos, João Paulo M. Pitelli, João C. A. Barata
We develop a localized particle detector model formulated as a massive quantum field on Minkowski spacetime with the spatial origin excised. To render the problem well posed at the…
Vacuum fluctuations and the renormalized stress-energy tensor on a cone with arbitrary boundary conditions
João Paulo M. Pitelli, Ricardo A. Mosna, Victor Hugo M. Ramos +1
We analyze the vacuum fluctuations and the stress-energy tensor of a scalar field of mass in a conical spacetime, where the topological singularity at the apex requires boundar…
Kiselev black strings: the charged rotating solutions
Leonardo G. Barbosa, Victor Hugo M. Ramos, Luis Cesar N. dos Santos +1
We investigate the properties of a charged rotating black string immersed in a Kiselev anisotropic fluid in anti-de Sitter (AdS) spacetime. The Einstein-Maxwell equations with an a…
