New Trends in First Quantisation: Field Theory, Gravity and Quantum Computing

Our current best understanding of nature at its fundamental level is based on field theories:
Einstein's theory of gravity on cosmological scales, or quantum field theory describing interactions between elementary particles on sub-microscopic scales. Complementary to long-established conventional methods, several theoretical branches of fundamental physics based on the framework of first quantisation have blossomed during recent years, driven either by technological, observational or experimental advances.

The aim of this workshop is to cultivate a common set of strategies among these research communities, identifying shared challenges, exchanging cutting edge theoretical tools, and fostering new interdisciplinary collaborations.
The workshop will bring together researchers from around the world primarily working on the following list of themes:

● Foundations of the first quantised worldline approach to quantum field theory, with
applications in elementary particle physics.
● Gravity in the first quantised approach, applied to binary mergers and gravitational
wave phenomena.
● Non-perturbative techniques in first quantisation, applied to physics at the high
amplitude frontier.
● Quantum computing in first quantised frameworks.

Invited talks are expected to present up-to-date results while keeping them accessible to non-experts. These talks will lead discussion sessions, which will have a prominent role to enhance cross-community knowledge exchange. Early career researchers and researchers from underrepresented backgrounds in the community will be highly encouraged to participate.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
