Junction conditions in a general field theory
Bence Racskó
It is well-known in the modified gravity scene that the calculation of junction conditions in certain complicated theories leads to ambiguities and conflicts between the various fo…
Geometrical and physical interpretation of the Levi-Civita spacetime in terms of the Komar mass density
Bence Racskó, László Á. Gergely
We revisit the interpretation of the cylindrically symmetric, static vacuum Levi-Civita metric, known in either Weyl, Einstein-Rosen, or Kasner-like coordinates. Despite the infini…
Variational formalism for generic shells in general relativity
Bence Racskó
We investigate the variational principle for the gravitational field in the presence of thin shells of completely unconstrained signature (generic shells). Such variational formula…
Lanczos equation on light-like hypersurfaces in a cosmologically viable class of kinetic gravity braiding theories
Bence Racskó, László Árpád Gergely
We discuss junction conditions across null hypersurfaces in a class of scalar-tensor gravity theories with i) second order dynamics, ii) obeying the recent constraints imposed by g…
Light-like shockwaves in scalar-tensor theories
Bence Racskó, László Árpád Gergely
Both electromagnetic shock-waves and gravitational waves propagate with the speed of light. If they carry significant energy-momentum, this will change the properties of the space-…
