A landscape of 4d N=1 SCFTs with a=c
Monica Jinwoo Kang, Craig Lawrie, Ki-Hong Lee +1
We study a landscape of four-dimensional superconformal field theories (SCFTs) with identical central charges. These theories are obtained by renormalization group…
Improved statistics for F-theory standard models
Martin Bies, Mirjam Cvetič, Ron Donagi +1
Much of the analysis of F-theory-based Standard Models boils down to computing cohomologies of line bundles on matter curves. By varying parameters one can degenerate such matter c…
Numerical spectra of the Laplacian for line bundles on Calabi-Yau hypersurfaces
Anthony Ashmore, Yang-Hui He, Elli Heyes +1
We give the first numerical calculation of the spectrum of the Laplacian acting on bundle-valued forms on a Calabi-Yau three-fold. Specifically, we show how to compute the approxim…
The Branes Behind Generalized Symmetry Operators
Jonathan J. Heckman, Max Hübner, Ethan Torres +1
The modern approach to -form global symmetries in a -dimensional quantum field theory (QFT) entails specifying dimension topological generalized symmetry operators wh…
The anomaly that was not meant IIB
Arun Debray, Markus Dierigl, Jonathan J. Heckman +1
Type IIB supergravity enjoys a discrete non-Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group t…
-corrected Poisson-Lie T-duality
Falk Hassler, Thomas Rochais
We propose leading order -corrections to the Poisson-Lie T-duality transformation rules of the metric, -field, and dilaton. Based on Double Field Theory, whose corrections t…
