Oscar Loaiza-Brito, Johannes Martin, Hans Peter Nilles +1
Flux compactifications of string theory seem to require the presence of a fine-tuned constant in the superpotential. We discuss a scheme where this constant is replaced by a dynami…
Cosmological Perturbations in Flux Compactifications
Johannes U. Martin
Kaluza-Klein compactifications with four-dimensional inflationary geometry combine the attractive idea of higher dimensional models with the attempt to incorporate four-dimensional…
BRANECODE: A Program for Simulations of Braneworld Dynamics
Johannes Martin, Gary N. Felder, Andrei V. Frolov +2
We describe an algorithm and a C++ implementation that we have written and made available for calculating the fully nonlinear evolution of 5D braneworld models with scalar fields.…
Exact identification of the radion and its coupling to the observable sector
Lev Kofman, Johannes Martin, Marco Peloso
Braneworld models in extra dimensions can be tested in laboratory by the coupling of the radion to the Standard Model fields. The identification of the radion as a canonically norm…
Braneworld dynamics with the BraneCode
Johannes Martin, Gary N. Felder, Andrei V. Frolov +2
We give a full nonlinear numerical treatment of time-dependent 5d braneworld geometry, which is determined self-consistently by potentials for the scalar field in the bulk and at t…
