Smooth Polar B-Splines with High-Order Regularity at the Origin
Peiyou Jiang, Roman Hatzky, Zhixin Lu +5
We introduce a smooth B-spline discretization in polar coordinates on the unit disc that corrects the loss of regularity present at the origin caused by the coordinate singularity…

The Linearized Vlasov-Maxwell System as a Hamiltonian System
Dominik Bell, Martin Campos Pinto, Stefan Possanner +1
We present a Hamiltonian formulation for the linearized Vlasov-Maxwell system with a Maxwellian background distribution function. We discuss the geometric properties of the model a…

Kinetic theory of motility induced phase separation for active Brownian particles
Rodrigo Soto, Martin Pinto, Ricardo Brito
When two active Brownian particles collide, they slide along each other until they can continue their free motion. For persistence lengths much larger than the particle diameter, t…
