Chern Index of Taub-Bolt instantons in Einstein-Born-Infeld gravity

30 Jun 2018  ·  Flores-Alfonso Daniel, Quevedo Hernando ·

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 Einstein-Born-Infeld theory which has electric and magnetic flux proportional to each other. Magnetic flux is found to be essentially a winding number and the electric flux turns out to be indexed by it.
