26. Symmetries, holography and integrability in NR string theory in SNC AdS5×S5

Juan Miguel Nieto García (Universität Hamburg)

29/04/2025, 14:00

Theme 1: Non-relativistic session

Integrability and holography have played a huge role in understanding string theory in AdS${}_5\times$S${}^5$, so it is worth studying if they survive in the non-relativistic string theory. In this talk, I will show that the Maldacena's construction of the AdS${}_5$/CFT${}_4$ correspondence survives the limit process, giving us a duality between NR string theory in SNC AdS${}_5\times$S${}^5$ and...

16. M(atrix)-Theory from Nonrelativistic Sigma Models

Dr Ziqi Yan (Nordita)

29/04/2025, 14:30

Theme 1: Non-relativistic session

I will talk about two classes of nonrelativistic sigma models and their roles in M-theory and matrix theory. I will start with the quantum critical supermembrane and its quantization, which is described by a renormalizable three-dimensional sigma model at a z=2 Lifshitz point. This model provides a natural candidate high-energy completion of the supermembrane in M-theory, where the latter is...

27. The Surprising Structure of Non-Relativistic 11-dimensional Supergravity

Chris Blair

29/04/2025, 15:30

Theme 1: Non-relativistic session

I will discuss the surprising structure of non-relativistic 11-dimensional supergravity, and some of its supersymmetric solutions, based on https://arxiv.org/abs/2407.21648 and https://arxiv.org/abs/2503.21577

31. Towards a covariant approach to post-Newtonian gravity

Jørgen Sandøe Musaeus (University of Edinburgh)

29/04/2025, 16:00

Theme 1: Non-relativistic session

In this talk, I will show how we used the covariant $1/c$-expansion to construct a framework for post-Newtonian gravity that is valid in any gauge with a Newtonian regime. This is not true for every gauge as Newtonian gravity itself is a gauge fixed version of Newton-Cartan gravity. Thus, we fix the leading order gauge choice but keep full gauge freedom at all subleading orders in this...
