A new instability in clustering dark energy?
Farbod Hassani, Julian Adamek, Martin Kunz +2
In this paper, we study the effective field theory (EFT) of dark energy for the -essence model beyond linear order. Using particle-mesh -body simulations that consistently so…
A new nonlinear instability for scalar fields
Farbod Hassani, Pan Shi, Julian Adamek +2
In this letter we introduce the non-linear partial differential equation (PDE) showing a new type of instability. Such equations appear in…
Braneworlds, graviton production, dynamical Casimir effect
Ruth Durrer, Marcus Ruser, Marc Vonlanthen +1
If our Universe is a 3+1 brane in a warped 4+1 dimensional bulk so that its expansion can be understood as the motion of the brane in the bulk, the time dependence of the boundary…
Graviton production in anti-de Sitter braneworld cosmology: A fully consistent treatment of the boundary condition
Marcus Ruser, Ruth Durrer, Marc Vonlanthen +1
In recent work by two of us, [Durrer & Ruser, PRL 99, 071601 (2007); Ruser & Durrer PRD 76, 104014 (2007)], graviton production due to a moving spacetime boundary (braneworld) in a…
