Copernicus Webinar and Colloquium Series

Europe/Zurich
Description

To promote scientific discussions during this pandemic, we are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.

We would like to invite you to take part in the upcoming 50th Webinar talk,
 

speaker:          Tevong You (CERN)

Time:             22nd June, Tuesday, 3pm CEST (9pm Beijing time, 10pm JST, 9am EDT)

Title :  Self-Organised Localisation

Abstract: We 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.
