Abstract: In this talk, I will present the motivation and brief history of perturbative algebraic quantum field theory (pAQFT). It has its roots in the axiomatic framework of Haag and Kastler, but uses the more pragmatical approach of perturbative QFT for the construction of models. At the same time, the methods used in pAQFT are mathematically rigorous, as renormalization is treated using the Epstein-Glaser approach, where physical quantities can be constructed without the need of "subtracting infinities".

Tricontinental Quantum Fundamentals Seminar

Series comments: The Tricontinental Quantum Fundamentals Seminar (3C-QFS) is an online seminar series connecting researchers from Australia, Europe, and America. Our goal is to facilitate discussion between the three continents and bring together those working on foundational topics in relativistic quantum physics, covering but not limited to:

  • Measurement, localisation, and causality in relativistic quantum theory
  • Energy conditions and quantum inequalities
  • Non-locality and observer-dependence of entanglement
  • Quantum reference frames and symmetries in quantum theory
  • Holography, AdS/CFT, and analogue gravity
For 3C-QFS, we wish to foster an inclusive community and promote open discussion by encouraging a casual atmosphere during the seminars.

The seminars are held online via Zoom, consisting of 40-60 minute talks followed by additional time for questions. We meet every three weeks on Tuesday, alternating between two times in order to connect research communities across two of the three continents.

For those unable to join the seminars live, talks are recorded and hosted on the 3C-QFS YouTube channel.

The seminar series is primarily for students and academics active in the foundations of physics. To sign up for the mailing list and join the seminars live, please complete the registration form on the 3C-QFS website.
