Chern Index of Taub-Bolt instantons in Einstein-Born-Infeld gravity
Daniel Flores-Alfonso, Hernando Quevedo
Partition functions can be calculated by saddle point approximations whenever regular solutions exist, as they dominate the path integral. We examine a regular Taub-Bolt dyon of Ei…
Topological Characterization of Higher Dimensional Charged Taub-NUT Instantons
Daniel Flores-Alfonso, Hernando Quevedo
Recently, we have shown that non-selfdual self-gravitating dyonic fields with magnetic mass generalize the Dirac monopole. The unique topological index, which characterizes the fie…
Flux quantization in dilatonic Taub-NUT dyons
Daniel Flores-Alfonso, Hernando Quevedo
Spacetimes that include a boundary at infinity have a non-trivial topology. The homology of the background influences gauge fields living on them and lead to topological charges. W…
Nonperturbative quantization à la Heisenberg and thermodynamics of monopole configurations
Vladimir Dzhunushaliev, Vladimir Folomeev, Hernando Quevedo
For field theories in which no small parameter is available, we propose a definition of nonperturbative quantum states in terms of the complete set of Green functions, based upon t…
Geometrothermodynamics in Horava-Lifshitz gravity
Hernando Quevedo, Alberto Sanchez, Safia Taj +1
We investigate the thermodynamic geometries of the most general static, spherically symmetric, topological black holes of the Hořava--Lifshitz gravity. In particular, we show that…
Thermodynamic systems as bosonic strings
H. Quevedo, A. Sanchez, A. Vazquez
We apply variational principles in the context of geometrothermodynamics. The thermodynamic phase space and the space of equilibrium states turn out to be des…
