Noninvertible Gauge Symmetry in (2+1)d Topological Orders: A String-Net Model Realization
Yidun Wan - Fudan University
In this talk, we develop a systematic framework for understanding symmetries in topological phases in \(2+1\) dimensions using the string-net model, encompassing both gauge symmetries that preserve anyon types and global symmetries permuting anyon types, including both invertible symmetries… -
The gravitational index of 5d black holes and black strings
Luca Iliesiu
In this talk, I will discuss how one can use the gravitational path integral to compute the supersymmetric index of black holes as well as other black objects in string theory. The saddles that I shall describe admit a non-zero temperature, consequently lacking an infinitely long AdS throat that… -
A new construction of $c=1$ Virasoro conformal blocks
Qianyu Hao
The Virasoro conformal blocks are very interesting since they have many connections to other areas of math and physics. For example, when $c=1$, they are related to tau functions of integrable systems of Painlev\'{e} equations. They are also closely related to non-perturbative completions in the… -

Stringy Gregory-Laflamme
Marija Tomašević - University of Amsterdam
Thin enough black strings are unstable to rippling along their length, and the instability threshold indicates that static inhomogeneous black strings exist. These have indeed been constructed with increasing inhomogeneity until a high-curvature singular pinch appears. We study the string-scale… -

String amplitudes in AdS: an emergent worldsheet picture
Maria Nocchi - University of Oxford
The study of string scattering in general curved spacetimes presents a stark contrast to the relatively well-understood framework in flat space, where perturbative techniques and worldsheet methods can be used. However, the AdS/CFT correspondence offers a powerful indirect method to compute string… -
The Quantum Mechanics of Spherically Symmetric Causal Diamonds
Temple He - California Institute of Technology (Caltech)
We construct the phase space of a spherically symmetric causal diamond in (d+2)-dimensional Minkowski spacetime. Utilizing the covariant phase space formalism, we identify the relevant degrees of freedom that localize to the d-dimensional bifurcate horizon and, upon canonical quantization, determine… -
Multi-loop Null Polygons from Fishnet theory to N=4 SYM
Enrico Olivucci - Irréversible Inc
"Null Polygons" in N=4 SYM theory describe the multi-point correlators of 1/2-BPS local operators with large R-charge, when they approach the vertices of a light-like polygon. The leading UV divergences of null polygons is conjectured to satisfy a hierarchy of coupled Toda field theory equations [E… -
Double Scaled SYK and de Sitter Holography
Herman Verlinde - Princeton University
In this talk I will describe the correspondence between the double scaling limit of the SYK model and infinite temperature and de Sitter gravity in 2 and 3 dimensions. The dictionary involves a precise match between the chord rules that govern the SYK correlation functions and the braid interactions… -
Resurgence and non-perturbative effects in topological string theory
Marcos Marino - University of Geneva (UNIGE)
Topological strings are well understood in perturbation theory, but their non-perturbative structure has been the subject of much work and speculation. A useful approach to this problem is to unveil the non-perturbative sectors of the theory by looking at the large order behavior of the perturbative…
