21. Towards a Flat Space Carrollian Hologram from AdS/CFT

Romain Ruzziconi (University of Oxford)

30/04/2025, 14:00

Theme 2: Carroll session

Carrollian holography proposes that gravity in four-dimensional (4d) asymptotically flat spacetime is dual to a 3d Carrollian CFT living at null infinity. In this talk, I will review this framework and explain how massless amplitudes in flat space can be re-expressed as Carrollian CFT correlators at the boundary, referred to as Carrollian amplitudes. I will show that these correlators...

10. Null Open Strings and Boundary Conformal CFTs

Dr Priyadarshini Pandit (Indian Institute of Technology Kanpur)

30/04/2025, 14:30

Theme 2: Carroll session

We study null open strings and establish, for the first time, that the worldsheet residual gauge symmetry algebra is the Boundary Carrollian Conformal Algebra (BCCA). We present the construction of open null strings and demonstrate that, under Dirichlet boundary conditions, Boundary Carrollian Conformal Algebra emerges as the algebra of constraints. Additionally, we show that the BCCA can be...

19. A Conformal Approach to Carroll Gravity

Jan Rosseel (Ruder Boskovic Institute)

30/04/2025, 15:30

Theme 2: Carroll session

In this talk, I will outline how to take the first step in the conformal program for constructing general matter couplings to Carroll gravity. In particular, I will show how a (non-conformal version of) electric/magnetic Carroll gravity arises from gauge-fixing a theory of a single massless electric/magnetic scalar coupled to conformal Carroll gravity with isotropic dilatations. Special...

25. From a covariant Maxwell-like theory to fractons: a new approach

Dr Erica Bertolini (Dublin Institute for Advanced Studies)

30/04/2025, 16:00

Theme 2: Carroll session

The concept of fracton quasiparticle has recently emerged in many areas of physics, from mathematical physics to condensed matter and quantum information, unified by the general feature of restricted mobility.

In this talk I will show that the fracton phenomenology of Pretko's original papers [1604.05329,1606.08857] can be reproduced from first principles of QFT through a symmetry-based...
