Traversable wormholes without exotic matter in multimetric repulsive gravity
Manuel Hohmann
We present a static, spherically symmetric, traversable wormhole solution to multimetric gravity which is sustained by only non-exotic matter, i.e., matter which satisfies all ener…
Parameterized post-Newtonian formalism for multimetric gravity
Manuel Hohmann
We discuss the post-Newtonian limit of multimetric gravity theories with metric tensors and a corresponding number of standard model copies, and construct an extension o…
Post-Newtonian parameters gamma and beta of scalar-tensor gravity with a general potential
Manuel Hohmann, Laur Jarv, Piret Kuusk +1
We calculate the PPN parameters gamma and beta for scalar-tensor gravity with a generic coupling function omega and scalar potential V in the Jordan conformal frame in the case of…
Extensions of Lorentzian spacetime geometry: From Finsler to Cartan and vice versa
Manuel Hohmann
We briefly review two recently developed extensions of the Lorentzian geometry of spacetime and prove that they are in fact closely related. The first is the concept of observer sp…
