Transport barriers to self-propelled particles in fluid flows
Simon A. Berman, John Buggeln, David A. Brantley +2
We present theory and experiments demonstrating the existence of invariant manifolds that impede the motion of microswimmers in two-dimensional fluid flows. One-way barriers are ap…
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…
Inclusion of Coulomb effects in laser-atom interactions
Jonathan Dubois, Simon Berman, Cristel Chandre +1
We investigate the role of the Coulomb interaction in strong field processes. We find that the Coulomb field of the ion makes its presence known even in highly intense laser fields…
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…
Variational formulation of classical and quantum models for intense laser pulse propagation
Simon Berman, Cristel Chandre, Jonathan Dubois +3
We consider the theoretical description of intense laser pulses propagating through gases. Starting from a first-principles description of both the electromagnetic field and the el…
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…
