Quantum Transitions Between Minkowski and de Sitter Spacetimes
Senarath P. de Alwis, Francesco Muia, Veronica Pasquarella +1
Quantum transitions among de Sitter and Minkowski spacetimes through bubble nucleation are revisited using the Hamiltonian formalism. We interpret tunnelling probabilities as relat…
The Fate of Dense Scalar Stars
Francesco Muia, Michele Cicoli, Katy Clough +3
Long-lived pseudo-solitonic objects, known as oscillons/oscillatons, which we collectively call real scalar stars, are ubiquitous in early Universe cosmology of scalar field theori…
Cosmology in the presence of multiple light moduli
Bobby S. Acharya, Mansi Dhuria, Diptimoy Ghosh +2
The generic expectation in string/supergravity models is that there are multiple moduli fields with masses of the order of the supersymmetry breaking scale. We study the cosmology…
