First Quantisation for Physics in Strong Fields

Event description

First quantised, or worldline, approaches to QFT are growing in popularity, not least due to recent successes in the areas of QFT in strong fields, and in the amplitudes-based approach to the classical 2-body problem in GR. Moreover, the worldline approach has a long history of providing non-perturbative information on processes in both QED and QCD, including at finite temperature.

The aim of this workshop is to bring members of different communities together to exchange ideas on worldline approaches to strong field physics, scattering amplitudes for classical gravity, and real-time path-integrals for cosmology.

The workshop format will include talks and extended discussion sessions in order to facilitate cross-disciplinary interactions.

All participants in HCTP activities are expected to show respect and courtesy to others throughout the duration of an event, including at social events. We draw the participants’ attention to the HCTP Code of Conduct
