Kerr-Newman black hole in a Melvin-swirling universe
Andrea Di Pinto, Silke Klemm, Adriano Viganò
We present a new exact solution of Einstein-Maxwell field equations which represents a rotating black hole with both electric and magnetic charges immersed in a universe which itse…
Rotating black holes with Nil or SL(2,) horizons
Federico Faedo, Silke Klemm, Pietro Mariotti
We construct rotating black holes in , minimal and matter-coupled gauged supergravity, with horizons that are homogeneous but not isotropic. Such spaces belong to the ei…
On SIR-type epidemiological models and population heterogeneity effects
Silke Klemm, Lucrezia Ravera
In this paper we elaborate on homogeneous and heterogeneous SIR-type epidemiological models. We find an unexpected correspondence between the epidemic trajectory of a transmissible…
Supersymmetric black holes with spiky horizons
Federico Faedo, Silke Klemm, Adriano Viganò
We use the recipe of arXiv:1003.2974 to find half-BPS near-horizon geometries in the t model of , gauged supergravity, and explicitely construct some new examples. A…
Schrödinger connection with selfdual nonmetricity vector in 2+1 dimensions
Silke Klemm, Lucrezia Ravera
We present a three-dimensional metric affine theory of gravity whose field equations lead to a connection introduced by Schrödinger many decades ago. Although involving nonmetricit…
An action principle for the Einstein-Weyl equations
Silke Klemm, Lucrezia Ravera
A longstanding open problem in mathematical physics has been that of finding an action principle for the Einstein-Weyl (EW) equations. In this paper, we present for the first time…
Black holes in Sol minore
Federico Faedo, Daniele Angelo Farotti, Silke Klemm
We consider black holes in five-dimensional -gauged supergravity coupled to vector multiplets, with horizons that are homogeneous but not isotropic. We write dow…
