We explore a correspondence between Melvin magnetic fluxtubes and anisotropic cosmological solutions, which we call `Melvin cosmologies'. The correspondence via analytic continuation provides useful information in both directions. Solution generating techniques known on the fluxtube side can also be used for generating cosmological backgrounds. Melvin cosmologies interpolate between different limiting Kasner behaviors at early and late times. This has an analogue on the fluxtube side between…

Spin precession in anisotropic cosmologies
We consider the precession of a Dirac particle spin in some anisotropic Bianchi universes. This effect is present already in the Bianchi-I universe. We discuss in some detail the geodesics and the
Cosmological magnetic field: The boost-symmetric case
With the notable exception of black holes, Einstein equations of general relativity are notoriously difficult to solve for exact solutions that would describe an astrophysically relevant situation
Construction of test Maxwell fields with scale symmetry
Geometrical symmetry in a spacetime can generate test solutions to the Maxwell equation. We demonstrate that the source-free Maxwell equation is satisfied by any generator of spacetime
Kasner branes with arbitrary signature
We present static and time-dependent solutions for the theory of gravity with a dilaton field and an arbitrary rank antisymmetric tensor. The solutions constructed are valid for arbitrary space-time
Geometry of AdS-Melvin spacetimes
We study asymptotically AdS generalizations of Melvin spacetimes, describing gravitationally bound tubes of magnetic flux. We find that narrow fluxtubes, carrying strong magnetic fields but little

The qualitative theory of dynamical systems is used to present an analysis of the phase space of Kaluza-Klein cosmological solutions with even-dimensional internal space, an arbitrary cosmological
Pseudo-supersymmetry and the domain-wall/cosmology correspondence
The correspondence between domain-wall and cosmological solutions of gravity coupled to scalar fields is explained. Any domain-wall solutions that admit a Killing spinor are shown to correspond to a
Hamilton-Jacobi method for Curved Domain Walls and Cosmologies
We use Hamiltonian methods to study curved domain walls and cosmologies. This leads naturally to first-order equations for all domain walls and cosmologies foliated by slices of maximal symmetry. For
Higher dimensional cylindrical or Kasner type electrovacuum solutions
We consider a $$D$$D dimensional Kasner type diagonal spacetime where metric functions depend only on a single coordinate and electromagnetic field shares the symmetries of spacetime. These solutions
Hidden supersymmetry of domain walls and cosmologies.
We show that all domain-wall solutions of gravity coupled to scalar fields for which the world-volume geometry is Minkowski or anti-de Sitter admit Killing spinors, and satisfy corresponding
Gauge fields and inflation
Abstract The isotropy and homogeneity of the cosmic microwave background (CMB) favors “scalar driven” early Universe inflationary models. However, gauge fields and other non-scalar fields are far
Decay of magnetic fields in Kaluza-Klein theory.
TLDR
It appears that fundamental fermions can eliminate the bubble decay of the magnetic field, while allowing the pair produciton of Kaluza-Klein monopoles.
Black holes in a magnetic universe
We present a general procedure for transforming asymptotically flat axially symmetric solutions of the Einstein–Maxwell equations into solutions resembling Melvin’s magnetic universe. Specific
