Active colloids in harmonic optical potentials
Buttinoni, Ivo; Caprini, Lorenzo; Alvarez, Laura; et al. (2022)
Europhysics Letters
We study the motion of active Janus colloids in an optical trap using experiments, theory and numerical simulations. To achieve isotropic and harmonic confinement, we prototype microparticles with a nearly uniform refractive index and verify that, in the absence of activity, the confined motion is identical to that of optically homogeneous Brownian particles. If the activity is turned on by means of vertical AC fields, the density distributions are described by Boltzmann-like statistics (Gaussian with effective temperature) only for strongly confining traps, whereas weaker potentials give rise to non-Gaussian distributions with a bimodal shape. Our results showcase a simple way to study active soft matter in optical potential landscapes eliminating the optical torque.

Tri-linear representations for the Laser Interferometer Space Antenna
Andersson, Fredrik; Riegger, Franziska; Ferraioli, Luigi; et al. (2022)
Europhysics Letters
The Laser Interferometer Space Antenna (LISA) is a space-borne observatory of gravitational waves to be launched by ESA and NASA in the 2030s. Interferometric measurements are made between three spacecraft orbiting the Sun. The measurements are dependent on the geometric information due to the relative locations between the spacecraft as well as the intrinsic parameters of the astrophysical objects that generate the gravitational waves. We show that the measurements of mildly chirping gravitational waves can be approximated by means of a tri-linear representation, where the geometric information about the location of the observed object as well as that of the spacecraft locations are separated by different factors. We discuss that for low frequencies the relative approximation error is proportional to the square of the signal's carrier frequency and illustrate this accuracy in numerical experiments. For the sake of illustration, we outline a simple algorithm for extracting parameters from the observed gravitational waves. ©
