Teleparallel bigravity
We write down the teleparallel equivalent to Hassan–Rosen bigravity, which is written using
a torsionful but curvature-free connection. The theories only differ by a boundary term. The …

Traversable wormholes in bimetric gravity
The ghost-free bimetric gravity theory is a viable theory of gravity that explores the
interaction between a massless and a massive graviton and can be described in terms of …

Spontaneous symmetry breaking in models with second-class constraints
In this work the spontaneous symmetry breaking in certain nonlinear theories with second-
class constraints is explored. Using the Dirac's method we perform an analysis of the …

Hamiltonian formalism of the ghost free tri (-multi) gravity theory
We study the Hamiltonian structure of tri-gravity and four-gravity in the framework of ADM
decomposition of the corresponding metrics. Hence we can deduce the general structure of …
