Self-propulsion of a polaron with an oscillating coupling to its quantum bath
Jacopo Romano, Andrea Gambassi
Motivated by the quest for active quantum matter, we investigate the dynamics of an impurity immersed in a quantum gas -- a polaron -- whose coupling to the surrounding medium is p…

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…

The OU process: Characterising dissipative confinement in noisy traps
Luca Cocconi, Henry Alston, Jacopo Romano +1
The Ornstein-Uhlenbeck (OU) process describes the dynamics of Brownian particles in a confining harmonic potential, thereby constituting the paradigmatic model of overdamped, mean-…
