From Action Principle to Stochastic Thermodynamics of Elastic and Viscous Active Matter
Valentina Barletta, Michele Lupini, Ian D. Estabrook +6
Motivated by the complex material properties of living matter, we derive a framework of stochastic thermo- and elastodynamics for active materials from the classical principle of l…
Modelling Active Non-Markovian Oscillations
Gennaro Tucci, Édgar Roldán, Andrea Gambassi +4
Modelling noisy oscillations of active systems is one of the current challenges in physics and biology. Because the physical mechanisms of such processes are often difficult to ide…
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…
Volterra-series approach to stochastic nonlinear dynamics: linear response of the Van der Pol oscillator driven by white noise
Roman Belousov, Florian Berger, A. J. Hudspeth
The Van der Pol equation is a paradigmatic model of relaxation oscillations. This remarkable nonlinear phenomenon of self-sustained oscillatory motion underlies important rhythmic…
A Volterra-series approach to stochastic nonlinear dynamics: The Duffing oscillator driven by white noise
Roman Belousov, Florian Berger, A. J. Hudspeth
The Duffing oscillator is a paradigm of bistable oscillatory motion in physics, engineering, and biology. Time series of such oscillations are often observed experimentally in a no…
Fluctuation theory in space and time: white noise in reaction-diffusion models of morphogenesis
Roman Belousov, Adrian Jacobo, A. J. Hudspeth
The precision of reaction-diffusion models for mesoscopic physical systems is limited by fluctuations. To account for this uncertainty, Van Kampen derived a stochastic Langevin-lik…
Nonequilibrium Langevin dynamics: a demonstration study of shear flow fluctuations in a simple fluid
Roman Belousov, E. G. D. Cohen, Lamberto Rondoni
The present study is based on a recent success of the second-order stochastic fluctuation theory in describing time autocorrelations of equilibrium and nonequilibrium physical syst…
Second-order fluctuation theory and time autocorrelation function for currents
Roman Belousov, E. G. D. Cohen
By using recent developments for the Langevin dynamics of spatially asymmetric systems, we routinely generalize the Onsager-Machlup fluctuation theory of the second order in time.…
The Langevin equation for systems with a preferred spatial direction
Roman Belousov, E. G. D. Cohen, Lamberto Rondoni
In this paper, we generalize the theory of Brownian motion and the Onsager-Machlup theory of fluctuations for spatially symmetric systems to equilibrium and nonequilibrium steady-s…
Asymmetry of steady state current fluctuations in nonequilibrium systems
Roman Belousov, E. G. D. Cohen
For systems in nonequilibrium steady states, a novel modulated Gaussian probability distribution is derived to incorporate a new phenomenon of biased current fluctuations, discover…
The impact of phonon dispersion on thermodynamical properties in computational models of crystalline solids
Roman Belousov, Mauro Prencipe
The existing techniques of account for the phonon dispersion are computationally costly, while its impact on a variety of thermodynamic properties appears negligible. We develop a…
Equations of state of magnesium perovskite and postperovskite: diagnostics from ab initio simulations
Roman Belousov, Mauro Prencipe
The isothermal compression of magnesium perovskite and postperovskite is examined through the F-f plot and the diagnostic plot of Vinet universal model theoretically from the ab in…
Statistical distribution of bonding distances in a unidimensional solid
Roman Belousov, Paolo De Gregorio, Lamberto Rondoni +1
We study a Fermi-Pasta-Ulam-like chain with realistic potentials, which models a unidimensional solid in contact with heat baths at some temperature. We formulate an explicit analy…
