From Flow to Jamming: Lattice Gas Automaton Simulations in Granular Materials
M. Gaber, Raquel H. Ribeiro, J. Kozicki
We introduce the first extension of a Lattice Gas Automaton (LGA) model to accurately replicate observed emergent phenomena in granular materials with a special focus on previously…
Entanglement masquerading in the CMB
Arsalan Adil, Andreas Albrecht, Rose Baunach +3
The simplest single-field inflation models capture all the relevant contributions to the patterns in the Cosmic Microwave Background (CMB) observed today. A key assumption in these…
Quantum quenches during inflation
Pedro Carrilho, Raquel H. Ribeiro
We propose a new technique to study fast transitions during inflation, by studying the dynamics of quantum quenches in an scalar field theory in de Sitter spacetime. We comp…
Double screening
Pierre Gratia, Wayne Hu, Austin Joyce +1
Attempts to modify gravity in the infrared typically require a screening mechanism to ensure consistency with local tests of gravity. These screening mechanisms fit into three broa…
Mild bounds on bigravity from primordial gravitational waves
Matteo Fasiello, Raquel H. Ribeiro
If the amplitude of primordial gravitational waves is measured in the near-future, what could it tell us about bigravity? To address this question, we study massive bigravity theor…
On the uniqueness of the non-minimal matter coupling in massive gravity and bigravity
Qing-Guo Huang, Raquel H. Ribeiro, Yu-Hang Xing +2
In de Rham-Gabadadze-Tolley (dRGT) massive gravity and bigravity, a non-minimal matter coupling involving both metrics generically re-introduces the Boulware--Deser (BD) ghost. A n…
