Les Houches – WE-Heraeus Workshop: Worldlines and path integrals in quantum field theory

Scientific Programme

This Les Houches – WE-Heraeus workshop will be organised around 5 topics, to be covered by the various contributions and collaborative discussion sessions.

Worldline foundations

1

Worldline foundations and theoretical developments in gauge theory and gravity

Quantum fields in external backgrounds

2

QFT in the presence of strong external background fields (e.g SFQED)

Heat kernels, resummation and resurgence

3

Heat kernel expansions, resummation of perturbative series and resurgence

On-shell path integrals

4

Calculation of wavefunctions or on-shell quantities in gauge theory – flat and curved space

Gravity and geometry in first quantisation

5

Gravity and geometry: from classical scattering to quantum anomalies
