Correspondence of phase transition points and singularities of thermodynamic geometry of black holes
We explore a formulation of thermodynamic geometry of black holes and prove
that the divergent points of the specific heat correspond exactly to the
singularities of the thermodynamic curvature. We investigate this
correspondence for different types of black holes. This formulation can also be
applied to an arbitrary thermodynamic system.Comment: 10 pages, 4 figures, typos fixed, references adde
Correlations between Abelian Monopoles and center vortices
We study the correlations between center vortices and Abelian monopoles for
SU() gauge group. Combining fractional fluxes of monopoles, center vortex
fluxes are constructed in the thick center vortex model. Calculating the
potentials induced by fractional fluxes constructing the center vortex flux in
a thick center vortex-like model and comparing with the potential induced by
center vortices, we observe an attraction between fractional fluxes of
monopoles constructing the center vortex flux. We conclude that the center
vortex flux is stable, as expected. In addition, we show that adding a
contribution of the monopole-antimonopole pairs in the potentials induced by
center vortices ruins the Casimir scaling at intermediate regime.Comment: 11 pages, 11 figures, Version accepted for publication in Nucl. Phys.
