Quantum Transitions, Detailed Balance, Black Holes and Nothingness
Sebastian Cespedes, Senarath de Alwis, Francesco Muia +1
We consider vacuum transitions by bubble nucleation among 4D vacua with different values and signs of the cosmological constant , including both up and down tunnelings. Followin…
Lifting Klein-Gordon/Einstein Solutions to General Nonlinear Sigma-Models: the Wormhole Example
Philippe Brax, C. P. Burgess, F. Quevedo
We describe a simple technique for generating solutions to the classical field equations for an arbitrary nonlinear sigma-model minimally coupled to gravity. The technique promotes…
Perils of Towers in the Swamp: Dark Dimensions and the Robustness of Effective Field Theories
C. P. Burgess, F. Quevedo
Recently there has been an interesting revival of the idea to use large extra dimensions to address the dark energy problem, exploiting the (true) observation that towers of states…
String Cosmology: from the Early Universe to Today
Michele Cicoli, Joseph P. Conlon, Anshuman Maharana +3
We review applications of string theory to cosmology, from primordial times to the present-day accelerated expansion. Starting with a brief overview of cosmology and string compact…
Testing BSM Physics with Gravitational Waves
Francesco Muia, Fernando Quevedo, Andreas Schachner +1
The Cosmic Gravitational Wave Background (CGWB) is an irreducible background of gravitational waves generated by particle exchange in the early Universe plasma. Standard Model part…
UV and IR Effects in Axion Quality Control
C. P. Burgess, Gongjun Choi, F. Quevedo
Motivated by recent discussions and the absence of exact global symmetries in UV completions of gravity we re-examine the axion quality problem (and naturalness issues more general…
