Stable wormholes in scalar-tensor theories
Gabriele Franciolini, Lam Hui, Riccardo Penco +2
We reconsider the issue of whether scalar-tensor theories can admit stable wormhole configurations supported by a non-trivial radial profile for the scalar field. Using a recently…
Effective Field Theory of Black Hole Quasinormal Modes in Scalar-Tensor Theories
Gabriele Franciolini, Lam Hui, Riccardo Penco +2
The final ringdown phase in a coalescence process is a valuable laboratory to test General Relativity and potentially constrain additional degrees of freedom in the gravitational s…
Behind Horndeski: Structurally Robust Higher Derivative EFTs
Luca Santoni, Enrico Trincherini, Leonardo G. Trombetta
Higher derivative scalar interactions can give rise to interesting cosmological scenarios. We present a complete classification of such operators that can yield sizeable effects wi…
Microscopic Features of Bosonic Quantum Transport and Entropy Production
Mihail Mintchev, Luca Santoni, Paul Sorba
We investigate the microscopic features of bosonic quantum transport in a non-equilibrium steady state, which breaks time reversal invariance spontaneously. The analysis is based o…
The Effective Theory of Shift-Symmetric Cosmologies
Bernardo Finelli, Garrett Goon, Enrico Pajer +1
A shift symmetry is a ubiquitous ingredient in inflationary models, both in effective constructions and in UV-finite embeddings such as string theory. It has also been proposed to…
