Critical Scaling of Compression-Driven Jamming of Athermal Frictionless Spheres in Suspension
Anton Peshkov, S. Teitel
We study numerically a system of athermal, overdamped, frictionless spheres, as in a non-Brownian suspension, in two and three dimensions. Compressing the system isotropically at a…
Boids in a Loop: Self-Propelled particles within a Flexible Boundary
A. C. Quillen, J. P. Smucker, A. Peshkov
We numerically explore the behavior of repelling and aligning self-propelled polar particles (boids) in 2D enclosed by a damped flexible and elastic loop-shaped boundary. We observ…
Generalized excitation of atomic multipole transitions by twisted light modes
S. A. -L. Schulz, A. A. Peshkov, R. A. Müller +5
A theoretical study is performed for the excitation of a single atom localized in the center of twisted light modes. Here we present the explicit dependence of excitation rates on…
Reversibility of granular rotations and translations
Anton Peshkov, Michelle Girvan, Derek C. Richardson +1
We analyze reversibility of both displacements and rotations of spherical grains in three-dimensional compression experiments. Using transparent acrylic beads with cylindrical hole…
Rayleigh scattering of twisted light by hydrogenlike ions
A. A. Peshkov, A. V. Volotka, A. Surzhykov +1
The elastic Rayleigh scattering of twisted light and, in particular, the polarization (transfer) of the scattered photons have been analyzed within the framework of second-order pe…
