Convergence Analysis of a Fully Discrete Observer For Data Assimilation of the Barotropic Euler Equations
Aidan Chaumet, Jan Giesselmann
We study the convergence of a discrete Luenberger observer for the barotropic Euler equations in one dimension, for measurements of the velocity only. We use a mixed finite element…
Step scaling with gradient flow and finite temperature
Parikshit M. Junnarkar, Guy D. Moore, Aidan Chaumet
We combine gradient flow, step-scaling, and finite-temperature boundary conditions to scale-set 2+1+1 flavor QCD lattices with physical HISQ quarks at multiple spacings down to a=0…
Improving Weak PINNs for Hyperbolic Conservation Laws: Dual Norm Computation, Boundary Conditions and Systems
Aidan Chaumet, Jan Giesselmann
We consider the approximation of entropy solutions of nonlinear hyperbolic conservation laws using neural networks. We provide explicit computations that highlight why classical PI…
Misalignment vs Topology in Axion-Like Models
Aidan Chaumet, Guy D. Moore
Cosmological axions, an important dark matter candidate, are generated when a scalar field with a spontaneously broken O(2) invariance develops an explicitly O(2)-breaking tilt cos…
