Mass formulas for supergravity black holes with string singularities
Igor Bogush, Dmitri Gal'tsov, Gérard Clément
We extend the derivation of mass formulas for stationary axisymmetric asymptotically locally flat solutions with string singularities on the polar axis to general supergravity acti…
The first law for stationary axisymmetric multi-black hole systems
Gérard Clément, Dmitry Gal'tsov
In the framework of Einstein-Maxwell theory, we consider collinear arrays of rotating electrically charged black holes connected by Misner-Dirac strings carrying gravimagnetic and…
Rotating traversable wormholes in Einstein-Maxwell theory
Gérard Clément, Dmitri Gal'tsov
It is well-known that traversable wormhole solutions to the Einstein equations require the existence of an exotic matter source violating the null energy condition. An apparent exc…
Spinning ring wormholes: a classical model for elementary particles?
Gérard Clément
Static horizonless solutions to the Einstein--Maxwell field equations, with only a circular cosmic string singularity, are extended to exact rotating asymptotically flat solutions.…
Gravitating Chern-Simons vortices
Gérard Clément
The construction of self-dual vortex solutions to the Chern-Simons-Higgs model (with a suitable eighth-order potential) coupled to Einstein gravity in (2 + 1) dimensions is reconsi…
