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…
Machine learning for cerebral blood vessels' malformations
Irem Topal, Alexander Cherevko, Yuri Bugay +5
Cerebral aneurysms and arteriovenous malformations are life-threatening hemodynamic pathologies of the brain. While surgical intervention is often essential to prevent fatal outcom…
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…
Learning the Hydrophilic, Hydrophobic and Aromatic Character of Amino Acids from their Interfacial Thermal Conductance in Water
Heydar Hamzi, Ali Rajabpour, Édgar Roldán +1
In this study, the thermal relaxation of the 20 naturally occurring amino-acids in water is investigated using transient non-equilibrium molecular-dynamics simulations. By modeling…
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…
