The work of this PhD investigates spontaneous collapse models, which are a proposed modification of quantum mechanics and their consistency with special relativity. Since soon after they were first proposed there have been many attempts to construct a relativistic collapse model, but currently there is not a satisfactory model. This thesis considers what it means for an irreversible dynamics to be consistent with special relativity and reviews the existing proposals and their issues.

Abstract
The work of this PhD investigates spontaneous collapse models, which are a proposed modification of quantum mechanics and their consistency with special relativity. Since soon after they were first proposed there have been many attempts to construct a relativistic collapse model, but currently there is not a satisfactory model. This thesis considers what it means for an irreversible dynamics to be consistent with special relativity and reviews the existing proposals and their issues. The key results are a demonstration of why a relativistic point-like collapse model is not possible and that a relativistic generalisation of one of the most studied collapse models, Continuous Spontaneous Localisation is not possible.File | Dimensione | Formato | |
