SUMMARY:Self-Organised Localisation
DESCRIPTION: I will describe a new phenomenon in quantum cosmology: self-organised localisation. When the fundamental parameters of a theory are functions of a scalar field subject to large fluctuations during inflation\, quantum phase transitions can act as dynamical attractors. As a result\, the theory parameters are probabilistically localised around the critical value and the Universe finds itself at the edge of a phase transition. We illustrate how self-organised localisation could account for the observed near-criticality of the Higgs self-coupling\, the naturalness of the Higgs mass\, or the smallness of the cosmological constant.
