Local symmetry and the dependence on extended spacetime
Keith Glennon, Peter West
We show that linearised E theory possesses a local symmetry at low levels provided the parameters of the local symmetry obey differential conditions that restrict their dependence…
Extended BMS representations and strings
Romain Ruzziconi, Peter West
We construct in detail the irreducible representations of the BMS group with super rotations in three and four dimensions that have the same rest frame momenta as the massive and m…
Duality symmetries and phase space quantum theory
Thomas Curtright, Peter West
We argue that duality symmetries can be manifestly realised when theories with these symmetries are quantised using phase space quantum theory. In particular, using background fiel…
The discovery of supergravity and its early development
Peter West
I give an account of the discovery of supergravity and the first six years of its development which lead to the most general coupling of supergravity to matter. I restrict the disc…
Base Models Beat Aligned Models at Randomness and Creativity
Peter West, Christopher Potts
Alignment has quickly become a default ingredient in LLM development, with techniques such as reinforcement learning from human feedback making models act safely, follow instructio…
Local symmetry and extended spacetime
Peter West
We show that the previously proposed local transformations in E theory have a closing algebra if one adopts a simple constraint on the parameters of the transformations that constr…
K27 as a symmetry of closed bosonic strings and branes
Keith Glennon, Peter West
We show that the dynamics encoded in the non-linear realisation of the semi-direct product of the very extended algebra K27 with its vector representation contains the low energy e…
Memories of Abdus Salam and the early days of supersymmetry
Peter West
I give an account of what it was like to be a PhD student of Abdus Salam and also to take part during the early stages of the development of supersymmetry.
