Nonlinear-Cost Random Walk: exact statistics of the distance covered for fixed budget
Satya N. Majumdar, Francesco Mori, Pierpaolo Vivo
We consider the Nonlinear-Cost Random Walk model in discrete time introduced in [Phys. Rev. Lett. 130, 237102 (2023)], where a fee is charged for each jump of the walker. The nonli…
Thermodynamic cost of finite-time stochastic resetting
Kristian Stølevik Olsen, Deepak Gupta, Francesco Mori +1
Recent experiments have implemented resetting by means of an external trap, whereby a system relaxes to the minimum of the trap and is reset in a finite time. In this work, we set…
Viscoelastic confinement induces periodic flow reversals in active nematics
Francesco Mori, Saraswat Bhattacharyya, Julia M. Yeomans +1
We use linear stability analysis and hybrid lattice Boltzmann simulations to study the dynamical behaviour of an active nematic confined in a channel made of viscoelastic material.…
Current fluctuations in stochastically resetting particle systems
Costantino Di Bello, Alexander K. Hartmann, Satya N. Majumdar +3
We consider a system of non-interacting particles on a line with initial positions distributed uniformly with density on the negative half-line. We consider two different model…
Cost of diffusion: nonlinearity and giant fluctuations
Satya N. Majumdar, Francesco Mori, Pierpaolo Vivo
We introduce a simple model of diffusive jump process where a fee is charged for each jump. The nonlinear cost function is such that slow jumps incur a flat fee, while for fast jum…
