Active matter encompasses systems whose individual constituents dissipate energy to exert
propelling forces on their environment. These systems exhibit dynamical phenomena with …

One of the major challenges in modern biology is to understand how the molecular
components of a living cell operate in a highly noisy environment. What are the specific …

We study the position distribution of an active Brownian particle (ABP) in the presence of
stochastic resetting in two spatial dimensions. We consider three different resetting …

We consider an overdamped run-and-tumble particle in two dimensions, with self-propulsion
in an orientation that stochastically rotates by 90∘ at a constant rate, clockwise or …

We propose and demonstrate purely optical feedback cooling of neutral nanoparticles in an
optical lattice to an occupation number of 0.85±0.20. The cooling force is derived from the …

We consider an active run-and-tumble particle (RTP) in d dimensions and compute exactly
the probability S (t) that the x component of the position of the RTP does not change sign up …

Abstract Run-and-tumble (RnT) motion is an example of active motility where particles move
at constant speed and change direction at random times. In this work we study RnT motion …

We study a set of run-and-tumble particle (RTP) dynamics in two spatial dimensions. In the
first case of the orientation θ of the particle can assume a set of n possible discrete values …

We study the noise-driven escape of active Brownian particles (ABPs) and run-and-tumble
particles (RTPs) from confining potentials. In the small noise limit, we provide an exact …

We study the statistics of the first-passage time of a single run-and-tumble particle (RTP) in
one spatial dimension, with or without resetting, to a fixed target located at L> 0. First, we …
