1. Bounded Collection of Feynman Integral Calabi-Yau Geometries / Bourjaily, Jacob L. ; McLeod, Andrew J. ; von Hippel, Matt ; Wilhelm, Matthias
We define the rigidity of a Feynman integral to be the smallest dimension over which it is nonpolylogarithmic. [...]

2. A quantum check of non-supersymmetric AdS/dCFT / Grau, Aleix ; Kristjansen, Charlotte ; Volk, Matthias ; Wilhelm, Matthias
Via a challenging field-theory computation, we confirm a supergravity prediction for the non-supersymmetric D3-D7 probe-brane system with probe geometry AdS 4 × S 2 × S 2 , stabilized by fluxes. [...]

3. The Hagedorn temperature of AdS 5 /CFT 4 at finite coupling via the Quantum Spectral Curve / Harmark, Troels ; Wilhelm, Matthias
Building on the recently established connection between the Hagedorn temperature and integrability [1] , we show how the Quantum Spectral Curve formalism can be used to calculate the Hagedorn temperature of AdS 5 /CFT 4 for any value of the 't Hooft coupling. [...]

5. Traintracks through Calabi-Yau Manifolds: Scattering Amplitudes beyond Elliptic Polylogarithms / Bourjaily, Jacob L. ; He, Yang-Hui ; McLeod, Andrew J. ; von Hippel, Matt ; et al
We describe a family of finite, four-dimensional, L-loop Feynman integrals that involve weight-(L+1) hyperlogarithms integrated over (L1)-dimensional elliptically fibered varieties we conjecture to be Calabi-Yau manifolds. [...]
