Constraining CFTs with moduli spaces
Adar Sharon - Stony Brook University
Moduli spaces of vacua are an intriguing property of certain supersymmetric QFTs which have been widely explored. However, a first-principles approach to moduli spaces and how they constrain observables is still lacking. This question is even more pressing due to recent interest in moduli spaces in… -
Quantum Many-body Bootstrap
Yuan Xin - Carnegie Mellon University
Determining the long-range phase of matter of a strongly coupled system from its microscopic description has long been one of the central topics in physics. Simple microscopic systems often become strongly coupled at long range where we usually rely on clever approximations. Bootstrap is an… -
Implications of the additivity anomaly in large N field theories for holography
Samuel Leutheusser - Institute for Advanced Study (IAS) - School of Natural Sciences (SNS)
Holographic conformal field theories exhibit dramatic changes in the structure of their operator algebras in the limit where the number of local degrees of freedom (N) becomes infinite. An important example of such phenomena is the violation of the additivity property for algebras associated to… -
Boundary vertex operator algebras of 3d N=4 rank-zero SCFTs.
Heeyeon Kim - Korea Advanced Institute of Science and Technology (KAIST)
I will talk about the boundary vertex operator algebra of topologically twisted 3d N=4 rank-zero SCFTs. The latter is recently introduced family of N=4 SCFTs with zero-dimensional Higgs and Coulomb branches, which are expected to support rational VOAs at the boundary. I will discuss the construction… -
Anomalous symmetries of spin chains
Anton Kapustin - California Institute of Technology (Caltech) - Division of Physics Mathematics & Astronomy
Several years ago, Nayak and Else argued that Symmetry Protected Topological phases in d dimensions can be classified using non-on-site actions of the symmetry group in d-1 dimensions. Such non-on-site actions can have an “anomaly”, in the sense that the symmetry action cannot be consistently… -
Reading between the sections of the Seiberg-Witten curve
Cyril Closset - University of Oxford
I will explore subtle aspects of rank-one 4d N=2 supersymmetric QFTs through their low-energy Coulomb-branch physics. The low-energy Lagrangian is famously encoded in "the Seiberg-Witten (SW) curve", which is a one-parameter family of elliptic curves. Here I will explain precisely how "global"… -
Do Euclidean Wormhole Saddles Contribute to the Factorization Problem?
Molly Kaplan - University of California, Santa Barbara
We investigate the nature of the Giddings-Strominger wormhole in axion gravity, whose stability remains contested despite previous work in this direction. Unlike what is done in these works, we follow a Lorentzian approach which directly addresses the factorization problem. To probe the… -
Gauging spacetime inversions - VIRTUAL
Daniel Lord Harlow - Massachusetts Institute of Technology (MIT) - Center for Theoretical Physics
Spacetime inversion symmetries such as parity and time reversal play a central role in physics, but they are usually treated as global symmetries. In quantum gravity there are no global symmetries, so any spacetime inversion symmetries must be gauge symmetries. In particular this includes CRT… -
Can one region of space encode another?
Charlie Cummings - University of Pennsylvania
Using a novel version of the gravitational path integral for compact spatial regions at a moment of time symmetry, I argue that a region of space can encode a larger one. In particular, I show that the entanglement entropy of a region of space equals the area of the boundary of the smallest region… -
