Description

This year's Triangular Conference on Cosmological Frontiers in Fundamental Physics will take place from the 19th - 21st of April 2024 at 50 George Square at the University of Edinburgh.

This conference is jointly organized by the Higgs Centre for Theoretical Physics in Edinburgh, the Astroparticle and Cosmology (APC) Laboratory in Paris, and the Perimeter Institute for Theoretical Physics in Waterloo. As always, the conference will include both theoretical and observational/experimental talks.  

Astronomical observations of the early universe reveal it to be as simple as can be, with no exotica observed thus far. Similarly, laboratory and accelerator experiments so far show no sign of particles beyond the Standard Model. The extreme economy and elegance of the observed universe poses a fundamental challenge for theoretical physics, demanding comparably minimal and elegant theoretical explanations. The focus of this workshop will be on looking for new theoretical explanations that are deeper, simpler and more rigid, and that explain why the universe is as simple as we observe it to be.

Speakers include:

Christopher Berry (Glasgow)

Sayantani Bhattacharya (NISER, Bhubaneswar)

Ana Bonaca (Carnegie Observatories)

Martin Bucher (APC)

Claudia De-Rham (Imperial)

Neal Dalal (Perimeter)

John Donoghue (Amherst)

      The University of Edinburgh

      50 George Square Edinburgh EH8 9LH

      The story I am presenting revolves around a strange and unfamiliar to most people geometric construction, which encodes a metric on a manifold into a collection of differential forms on the same manifold. There are many known examples, in diverse dimensions. In three dimensions this coincides with the encoding of a metric into a frame, but higher dimensional examples are much more sophisticated. One of the aims of the talk is to explain what is behind these phenomena.

      We will see that the construction that encodes a metric into a collection of differential forms has a spinor origin. Moreover, the encoding is always that for a pair (metric, spinor) = differential forms. I will give a detailed explanation of how this works in four dimensions, where the encoding is that into a triple of 2-forms. I will explain how four-dimensional Einstein equations are very efficiently described by this formalism. I will explain the generalisation to eight dimensions, which has only been worked out recently.

      I will also explain the physics motivations behind these investigations, which have to do with the idea of the dimensional reduction and the fact that all known fields can be coded into a metric and a spinor in a sufficiently high number of dimensions.
