Trapping of swimmers in a vortex lattice
S. A. Berman, K. A. Mitchell
We examine the motion of rigid, ellipsoidal swimmers subjected to a steady vortex flow in two dimensions. Numerical simulations of swimmers in a spatially periodic array of vortice…

Guiding-center motion for electrons in strong laser fields
Jonathan Dubois, S. Berman, C. Chandre +1
We consider the dynamics of electrons in combined strong laser and Coulomb fields. Under a timescale separation condition, we reduce this dynamics to a guiding-center framework. Mo…

Capturing photoelectron motion with guiding fictitious particles
Jonathan Dubois, Simon Berman, Cristel Chandre +1
Photoelectron momentum distributions (PMDs) from atoms and molecules undergo qualitative changes as laser parameters are varied. We present a model to interpret the shape of the PM…
