Microscopic entropy of de Sitter spacetime and entropic solution to the old cosmological constant problem
Mariano Cadoni, Lorenzo Herres, Lorenzo Orlando +1
We study the role of Weyl symmetry breaking in conformal gravity and the residual scale symmetry of Einstein gravity. The corresponding action is characterized by a dimensionless c…

Cosmological and Wormhole Solutions in Low-Energy Effective String Theory
Mariano Cadoni, Marco Cavaglia
We derive and study a class of cosmological and wormhole solutions of low-energy effective string field theory. We consider a general four-dimensional string effective action where…
