Dynamics of a tracer trapped in a correlated medium in the presence of a wall
Marcin Piotr Pruszczyk, Andrea Gambassi
We describe the random motion of a particle immersed in a thermally fluctuating medium and harmonically trapped at a certain distance from a wall. The medium, modeled by a Gaussian…
Anomalous diffusion and run-and-tumble motion of a chemotactic particle in low dimensions
Jacopo Romano, Andrea Gambassi
We study the stochastic dynamics of a symmetric self-chemotactic particle and determine the long-time behavior of its mean squared displacement (MSD). The attractive or repulsive i…
Recoil of a driven tracer in a correlated medium
Marcin Piotr Pruszczyk, Davide Venturelli, Andrea Gambassi
We study the stochastic dynamics of a Brownian particle after it is suddenly released from a harmonic trap moving with constant velocity through a fluctuating correlated medium, de…
Structure and dynamics of a Rouse polymer in a fluctuating correlated medium
Pietro Luigi Muzzeddu, Davide Venturelli, Andrea Gambassi
We study the static and dynamical properties of a harmonically confined Rouse polymer coupled to a fluctuating correlated medium, which affect each other reciprocally during their…
The XY model with vision cone: non-reciprocal vs. reciprocal interactions
Gabriele Bandini, Davide Venturelli, Sarah A. M. Loos +2
We study the behavior of the classical XY model on a two-dimensional square lattice, with interactions occurring within a vision cone of each spin. Via Monte Carlo simulations, we…
Self-diffusion anomalies of an odd tracer in soft-core media
Pietro Luigi Muzzeddu, Erik Kalz, Andrea Gambassi +2
Odd-diffusive systems, characterised by broken time-reversal and/or parity symmetry, have recently been shown to display counterintuitive features such as interaction-enhanced dyna…
