Averaging in LRS class II spacetimes
Petr Kaspar, Otakar Svitek
We generalize Buchert's averaged equations [Gen. Rel. Grav. 32, 105 (2000); Gen. Rel. Grav. 33, 1381 (2001)] to LRS class II dust model in the sense that all Einstein equations are…
Modelling Inhomogeneity in Szekeres Spacetime
David Vrba, Otakar Svitek
We study the behaviour of the density contrast in quasi-spherical Szekeres spacetime and derive its analytical behaviour as a function of and . We set up the inhomogeneity u…
Particles under radiation thrust in Schwarzschild space-time from a flux perpendicular to the equatorial plane
Donato Bini, Andrea Geralico, Robert T. Jantzen +1
Motivated by the picture of a thin accretion disc around a black hole, radiating mainly in the direction perpendicular to its plane, we study the motion of test particles interacti…
Graphene and Black Holes: novel materials to reach the unreachable
Alfredo Iorio
The case for a dedicated laboratory, to test hep-th models on analogue systems, is briefly made. The focus is on graphene.
Curved Spacetimes and Curved Graphene: a status report of the Weyl-symmetry approach
Alfredo Iorio
This is a status report about the ongoing work on the realization of quantum field theory on curved graphene spacetimes that uses Weyl symmetry. The programme is actively pursued f…
Stellar wind in state transitions of high-mass X-ray binaries
Jan Čechura, Petr Hadrava
Aims: We have developed a new code for the three-dimensional time-dependent raditation hydrodynamic simulation of the stellar wind in interacting binaries to improve models of accr…
