Abstract
Euclidean wormholes play a key role in Quantum Gravity (QG), and have been studied in relation with various aspects, as for instance the possible loss of quantum coherence, the black hole information paradox, the absence of global symmetries in quantum gravity and various ‘swampland’ criteria characterising the effective field theories (EFTs) compatible with QG. The thesis will investigate a large class of axionic wormholes in four-dimensional EFTs preserving N=2 supersymmetry, their relation to black holes in five dimensions, and their explicit realisation in string theory. Understanding this relation may provide a new perspective on the quantum gravity effects generated by wormholes, and their connection with other non-perturbative effects appearing in string theory.File | Dimensione | Formato | |
