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…
Non-reciprocal interactions between condensates in chemically active mixtures
Jacopo Romano, Martin Kjøllesdal Johnsrud, Benoît Mahault +1
We study the behaviour of catalytically active droplets in multi-component conserved mixtures affected by noise. Working in the thin interface limit, we analytically determine the…
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…
Dynamics of Phase-Separated Interfaces in Inhomogenous and Driven Mixtures
Jacopo Romano, Ramin Golestanian, Benoît Mahault
We derive effective equations of motion governing the dynamics of sharp interfaces in phase-separated binary mixtures driven by spatio-temporal modulations of their material proper…
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-…
Dynamical theory of topological defects II: Universal aspects of defect motion
Jacopo Romano, Benoît Mahault, Ramin Golestanian
We study the dynamics of topological defects in continuum theories governed by a free energy minimization principle, building on our recently developed framework [Romano J, Mahault…
