1. 6D N=(2,0) SCFTs at large-R-charge and the 2D conformal block

Masataka Watanabe

5/13/24, 9:30 AM

I will compute the OPE data of large-$R$-charge operators in 6D N=(2,0) SCFTs using the moduli effective action. Using the work of Beem, Rastelli, and Rees, this is related to the large-order behaviour of the 2D (Virasoro) conformal block. I will compute the 2D data numerically to show consistency with the result from 6D effective action. Based on these, a general conjecture about the...

4. Conformal ladder graphs as thermal partition functions

Anastasios Petkou

5/14/24, 11:00 AM

I describe a recently discovered correspondence between L-loop conformal ladder graphs in D=2 and D=4 fishnet CFTs, and thermal partition functions of massive free scalars in d=2L+1 dimensions. The correspondence reveals some previously unobserved algebraic and differential relations among the conformal graphs. It also provides a statistical field theory interpretation for the all-loop...

5. New perspective in fermionic CFTs at large charge

Nicola Dondi

5/14/24, 1:30 PM

I will present some results concerning large-charge sectors of 3d CFTs with fermionic degrees of freedom. I will focus on theories that are weakly coupled at large-N, allowing for analytic determination of finite-density ground states. Other than superfluid ground states, certain large-charge sectors are described by filled Fermi Sphere ground states, whose stability beyond the large-N...

6. Monodromy defects and holography

Matthew Roberts

5/15/24, 9:30 AM

With an aim to further quantify non-pertubative defects in quantum field theory, we study two-dimensional magnetic defects in four dimensional SUSY quantum field theories which preserve a two-dimensional superconformal symmetry along the defect. These can be thought of as an infrared limit of a magnetic solenoid. On general grounds such magnetic defects support localized chiral edge states,...

10. The EFT of Large Spin Mesons

Gabriel Cuomo

5/16/24, 11:00 AM

As well known, mesons with large spin J in large Nc QCD can be described as rotating open strings using effective field theory (EFT). However, some subtleties arise for light quarks, due to the breakdown of the derivative expansion near the endpoints. Building on previous works on the subject, I will describe a consistent treatment of such endpoints’ singularities and obtain results, in a...

13. An EFT approach to large charge convexity

Andrew Gomes

5/17/24, 11:00 AM

I will present recently understood aspects of large charge convexity, and its violation, using an EFT approach. We first distinguish between "quantum" and "semi-classical" violations of convexity. We then show that the latter, if they exist, are extremely constrained by the EFT. Based on work with Riccardo Rattazzi, Alexander Monin, and Tim Cohen.
