Anomaly constraints and string/F-theory geometry in 6D quantum gravity

, 2010
Quantum anomalies, determined by the Atiyah-Singer index theorem, place strong constraints on the space of quantum gravity theories in six dimensions with minimal supersymmetry.

Exploring 2-group global symmetries

Journal of High Energy Physics, 2019
We analyze four-dimensional quantum field theories with continuous 2-group global symmetries. At the level of their charges, such symmetries are identical to a product of continuous flavor or spacetime symmetries with a 1-form global symmetry U(1) B (1) ,

Quantum Symmetries and Stringy Instantons

, 1994
The quantum symmetry of many \LG\ orbifolds appears to be broken by Yang-Mills instantons. However, isolated Yang-Mills instantons are not solutions of string theory: They must be accompanied by gauge anti-instantons, gravitational instantons, or ...

Two-dimensional gauge anomalies and p-adic numbers

Journal of High Energy Physics
We show how methods of number theory can be used to study anomalies in gauge quantum field theories in spacetime dimension two. To wit, the anomaly cancellation conditions for the abelian part of the local anomaly admit solutions if and only if they ...

Quantum mechanical path integrals in curved spaces and the type-A trace anomaly

Journal of High Energy Physics, 2017
Path integrals for particles in curved spaces can be used to compute trace anomalies in quantum field theories, and more generally to study properties of quantum fields coupled to gravity in first quantization.

A holographic computation of the central charges of d=4, N=2 SCFTs

, 2008
We use the AdS/CFT correspondence to compute the central charges of the d=4, N=2 superconformal field theories arising from N D3-branes at singularities in F-theory. These include the conformal theories with E_n global symmetries.

Conformal chiral boson models on twisted doubled tori and non-geometric string vacua

, 2009
We derive and analyze the conditions for quantum conformal and Lorentz invariance of the duality symmetric interacting chiral boson sigma-models, which are conjectured to describe non-geometric string theory backgrounds.

Machine learning the 6d supergravity landscape

Journal of High Energy Physics
In this paper, we apply both supervised and unsupervised machine learning algorithms to the study of the string landscape and swampland in 6-dimensions. Our data are the (almost) anomaly-free 6-dimensional N $$ \mathcal{N} $$ = (1, 0) supergravity models,

String universality in ten dimensions

, 2010
We show that the ${\cal N}=1$ supergravity theories in ten dimensions with gauge groups $U(1)^{496}$ and $E_8 \times U(1)^{248}$ are not consistent quantum theories. Cancellation of anomalies cannot be made compatible with supersymmetry and abelian gauge
