Boundary effects on the thermal stability of a black hole at the centre of a conducting spherical shell
E. S. Moreira
This paper reports calculations and analysis of the effects of a perfect conducting wall of a very large spherical shell on the stable thermodynamic equilibrium of a black hole sit…
Hot scalar radiation around a cosmic string setting bounds on the coupling parameter
E. S. Moreira
In this work, by investigating the low temperature behaviour of a scalar field around a cosmic string, and assuming stable thermodynamic equilibrium, it is shown that the coupling…
Hot scalar radiation setting bounds on the curvature coupling parameter
V. A. De Lorenci, L. G. Gomes, E. S. Moreira
This paper addresses the interplay between vacuum and thermal local averages for massless scalar radiation near a plane wall of a large cavity where the Dirichlet boundary conditio…
Semiclassical backreaction around a nearly spinning cosmic string
Vitorio A. De Lorenci, Edisom S. Moreira
This paper investigates semiclassical backreaction of a conformally coupled massless scalar field on the geometrical background of a nearly spinning cosmic string - the spin densit…
Specific heat of a particle on the cone
E. S. Moreira, E. S. Oliveira
This work investigates how a conical singularity can affect the specific heat of systems. A free nonrelativistic particle confined to the lateral surface of a cone -- conical box -…
Semiclassical back reaction around a cosmic dislocation
V. A. De Lorenci, R. Klippert, E. S. Moreira
The energy-momentum vacuum average of a conformally coupled massless scalar field vibrating around a cosmic dislocation (a cosmic string with a dislocation along its axis) is taken…
