Oscillations and parity violation in gravitational wave background from extra tensor modes
Jaume Garriga, Mohammad Ali Gorji, Fazlollah Hajkarim +1
Spectator fields which provide additional tensor degrees of freedom, on top of the standard metric tensor perturbations, can produce significant amounts of gravitational waves (GWs…
Bigravity and Lorentz-violating Massive Gravity
D. Blas, C. Deffayet, J. Garriga
Bigravity is a natural arena where a non-linear theory of massive gravity can be formulated. If the interaction between the metrics and is non-derivative, spherically symme…
Global structure of bigravity solutions
Diego Blas, Cedric Deffayet, Jaume Garriga
We discuss the causal diagrams of static and spherically symmetric bigravity vacuum solutions, with interacting metrics and . Such solutions can be classified into type I (o…
Nucleation Rates in Flat and Curved Space
J. Garriga
Nucleation rates for tunneling processes in Minkowski and de Sitter space are investigated, taking into account one loop prefactors. In particular, we con- sider the creation of me…
