Macroscopic active matter under confinement: dynamical heterogeneity, bursts, and glassy behavior in a few-body system of self-propelling camphor surfers
Marco Leoni, Matteo Paoluzzi, Christian Alistair Dumaup +5
We study a few-body system composed of self-propelling camphor surfers confined within a circular boundary. These millimeter-sized particles move in a regime where inertia and long…
Inertia suppresses signatures of activity of active Brownian particles in a harmonic potential
Angelica Arredondo, Catania Calavitta, Mauricio Gomez +3
A harmonically trapped active Brownian particle exhibits two types of positional distributions -- one has a single peak, the other has a single well -- that signify steady-state dy…
Non-equilibrium fluctuations and nonlinear response of an active bath
Hunter Seyforth, Mauricio Gomez, W. Benjamin Rogers +2
We analyze the dynamics of a passive colloidal probe immersed in an active bath using an optical trap to study three physical processes: (1) the non-equilibrium fluctuations transf…
Comparison of different approaches to single-molecule imaging of enhanced enzyme diffusion
Mengqi Xu, W. Benjamin Rogers, Wylie W. Ahmed +1
Enzymes have been shown to diffuse faster in the presence of their reactants. Recently, we revealed new insights into this process of enhanced diffusion using single-particle track…
Stochastic force dynamics of the model microswimmer Chlamydomonas reinhardtii: Active forces and energetics
Corbyn Jones, Mauricio Gomez, Ryan M. Muoio +4
We study the stochastic force dynamics of a model microswimmer (Chlamydomonas reinhardtii), using a combined experimental, theoretical, and numerical approach. While swimming dynam…
Surfing and crawling macroscopic active particles under strong confinement -- inertial dynamics
Marco Leoni, Matteo Paoluzzi, Sarah Eldeen +5
We study two types of active (self-propelled) macroscopic particles under confinement: camphor surfers and hexbug crawlers, using a combined experimental, theoretical, and numerica…
Quantifying the non-equilibrium activity of an active colloid
Sarah Eldeen, Ryan Muoio, Paris Blaisdell-Pijuan +4
Active matter systems exhibit rich emergent behavior due to constant injection and dissipation of energy at the level of individual agents. Since these systems are far from equilib…
Small-scale displacement fluctuations of vesicles in fibroblasts
Danielle Posey, Paris Blaisdell-Pijuan, Samantha K. Knoll +2
The intracellular environment is a dynamic space filled with various organelles moving in all directions. Included in this diverse group of organelles are vesicles, which are invol…
Nonequilibrium dissipation in living oocytes
Étienne Fodor, Wylie W. Ahmed, Maria Almonacid +6
Living organisms are inherently out-of-equilibrium systems. We employ new developments in stochastic energetics and rely on a minimal microscopic model to predict the amount of mec…
Active mechanics reveal molecular-scale force kinetics in living oocytes
Wylie W. Ahmed, Etienne Fodor, Maria Almonacid +6
Active diffusion of intracellular components is emerging as an important process in cell biology. This process is mediated by complex assemblies of molecular motors and cytoskeleta…
