The Lorentz Anomaly via Operator Product Expansion
Stefan Fredenhagen, Jens Hoppe, Mariusz Hynek
The emergence of a critical dimension is one of the most striking features of string theory. One way to obtain it is by demanding closure of the Lorentz algebra in the light-cone g…
Grassmannian Integrals as Matrix Models for Non-Compact Yangian Invariants
Nils Kanning, Yumi Ko, Matthias Staudacher
In the past years, there have been tremendous advances in the field of planar N=4 super Yang-Mills scattering amplitudes. At tree-level they were formulated as Grassmannian integra…
Filtrations in Dyson-Schwinger equations: next-to^{j} -leading log expansions systematically
Olaf Krueger, Dirk Kreimer
Dyson-Schwinger equations determine the Green functions in quantum field theory. Their solutions are triangular series in a coupling constant and an external scale p…
T-duality, Non-geometry and Lie Algebroids in Heterotic Double Field Theory
Ralph Blumenhagen, Rui Sun
A number of issues in heterotic double field theory are studied. This includes the analysis of the T-dual configurations of a flat constant gauge flux background, which turn out to…
Towards one-loop SYM amplitudes from the pure spinor BRST cohomology
Carlos R. Mafra, Oliver Schlotterer
In this paper, we outline a method to compute supersymmetric one-loop integrands in ten-dimensional SYM theory. It relies on the constructive interplay between their cubic-graph or…
On Holographic Entanglement Entropy with Second Order Excitations
Song He, Jia-Rui Sun, Hai-Qing Zhang
We study the low-energy corrections to the holographic entanglement entropy (HEE) in the boundary CFT by perturbing the bulk geometry up to second order excitations. Focusing on th…
