Martingale theory for heat and phase-space contraction in heterogeneous diffusions
Jing Qin, Nariya Uchida, Édgar Roldán
We investigate martingale properties of heat dissipated by generic non-equilibrium overdamped Langevin dynamics with multiple dimensions and transport coefficients that may depend…
On the area swept by a biased diffusion till its first-exit time: Martingale approach and gambling opportunities
Yonathan Sarmiento, Debraj Das, Édgar Roldán
Using martingale theory, we compute, in very few lines, exact analytical expressions for various first-exit-time statistics associated with one-dimensional biased diffusion. Exampl…
Brownian particle in a Poisson-shot-noise active bath: exact statistics, effective temperature, and inference
Costantino Di Bello, Rita Majumdar, Rahul Marathe +2
We study the dynamics of an overdamped Brownian particle in a thermal bath that contains a dilute solution of active particles. The particle moves in a harmonic potential and exper…
Thermodynamics of computations with absolute irreversibility, unidirectional transitions, and stochastic computation times
Gonzalo Manzano, Gülce Kardeş, Édgar Roldán +1
Developing a thermodynamic theory of computation is a challenging task at the interface of non-equilibrium thermodynamics and computer science. In particular, this task requires de…
Stochastic thermodynamics of a probe in a fluctuating correlated field
Davide Venturelli, Sarah A. M. Loos, Benjamin Walter +2
We develop a framework for the stochastic thermodynamics of a probe coupled to a fluctuating medium with spatio-temporal correlations, described by a scalar field. For a Brownian p…
Taxis of cargo-carrying microswimmers in traveling activity waves
Pietro Luigi Muzzeddu, Édgar Roldán, Andrea Gambassi +1
Many fascinating properties of biological active matter crucially depend on the capacity of constituting entities to perform directed motion, e.g., molecular motors transporting ve…
Nonreciprocal nanoparticle refrigerators: design principles and constraints
Sarah A. M. Loos, Saeed Arabha, Ali Rajabpour +2
We study the heat transfer between two nanoparticles held at different temperatures that interact through nonreciprocal forces, by combining molecular dynamics simulations with sto…
Statistical physics of inhomogeneous transport: Unification of diffusion laws and inference from first-passage statistics
Roman Belousov, Ali Hassanali, Édgar Roldán
Characterization of composite materials, whose properties vary in space over microscopic scales, has become a problem of broad interdisciplinary interest. In particular, estimation…
First-passage Fingerprints of Water Diffusion near Glutamine Surfaces
Roman Belousov, Muhammad Nawaz Qaisrani, Ali Hassanali +1
The extent to which biological interfaces affect the dynamics of water plays a key role in the exchange of matter and chemical interactions that are essential for life. The density…
