Emergence of Calabi-Yau manifolds in high-precision black hole scattering
Mathias Driesse, Gustav Uhre Jakobsen, Albrecht Klemm +5
Using the worldline quantum field theory formalism, we compute the radiation-reacted impulse, scattering angle, radiated energy and recoil of a classical black hole (or neutron sta…
Weak Solutions for a non-Newtonian Stokes-Transport System
Dimitri Cobb, Geoffrey Lacour
In this article, we study a non-Newtonian Stokes-Transport system. This set of PDEs was introduced as a model for describing the behavior of a cloud of particles in suspension in a…
Existence and Uniqueness for the SQG Vortex-Wave System when the Vorticity is Constant near the Point-Vortex
Dimitri Cobb, Martin Donati, Ludovic Godard-Cadillac
This article studies the vortex-wave system for the Surface Quasi-Geostrophic equation with parameter 0 < s < 1. We obtained local existence of classical solutions in H^4 under the…
Mesh d-refinement: a data-based computational framework to account for complex material response
Sacha Wattel, Jean-François Molinari, Michael Ortiz +1
Model-free data-driven computational mechanics (DDCM) is a new paradigm for simulations in solid mechanics. The modeling step associated to the definition of a material constitutiv…
Topological Strings on Non-Commutative Resolutions
Sheldon Katz, Albrecht Klemm, Thorsten Schimannek +1
In this paper we propose a definition of torsion refined Gopakumar-Vafa (GV) invariants for Calabi-Yau threefolds with terminal nodal singularities that do not admit Kähler crepant…
Yangian-invariant fishnet integrals in 2 dimensions as volumes of Calabi-Yau varieties
Claude Duhr, Albrecht Klemm, Florian Loebbert +2
We argue that -loop Yangian-invariant fishnet integrals in 2 dimensions are connected to a family of Calabi-Yau -folds. The value of the integral can be computed from t…
