Lattice Boltzmann study of chemically-driven self-propelled droplets
F. Fadda, G. Gonnella, A. Lamura +1
We numerically study the behavior of self-propelled liquid droplets whose motion is triggered by a Marangoni-like flow. This latter is generated by variations of surfactant concent…
Effects of Nanoparticles on the Dynamic Morphology of Electrified Jets
Marco Lauricella, Dario Pisignano, Sauro Succi
We investigate the effects of nanoparticles on the onset of varicose and whipping instabilities in the dynamics of electrified jets. In particular, we show that the non-linear inte…
Anisotropic Gravitational Collapse and Cosmic Jets
Donato Bini, Carmen Chicone, Bahram Mashhoon
Consider a dynamic general relativistic spacetime in which the proper infinitesimal interval along one spatial coordinate direction decreases monotonically with time, while the cor…
Gravitational spin-orbit coupling in binary systems, post-Minkowskian approximation and effective one-body theory
Donato Bini, Thibault Damour
A novel approach for extracting gauge-invariant information about spin-orbit coupling in gravitationally interacting binary systems is introduced. This approach is based on the "sc…
Some examples of kinetic scheme whose diffusion limit is Il'in's exponential-fitting
Laurent Gosse, Nicolas Vauchelet
This paper is concerned with diffusive approximations of peculiar numerical schemes for several linear (or weakly nonlinear) kinetic models which are motivated by wide-range applic…
Efficient approximation of functions of some large matrices by partial fraction expansions
Daniele Bertaccini, Marina Popolizio, Fabio Durastante
Some important applicative problems require the evaluation of functions of large and sparse and/or \emph{localized} matrices . Popular and interesting techniques for computi…
Lattice Wigner equation
Sergio Solorzano, Miller Mendoza, Sauro Succi +1
We present a numerical scheme to solve the Wigner equation, based on a lattice discretization of momentum space. The moments of the Wigner function are recovered exactly, up to the…
On the force--velocity relationship of a bundle of rigid living filaments
Alessia Perilli, Carlo Pierleoni, Giovanni Ciccotti +1
In various cellular processes, biofilaments like F-actin and F-tubulin are able to exploit chemical energy associated to polymerization to perform mechanical work against an extern…
Hyperbolic scattering of spinning particles by a Kerr black hole
Donato Bini, Andrea Geralico, Justin Vines
We investigate the scattering of a spinning test particle by a Kerr black hole within the Mathisson-Papapetrou-Dixon model to linear order in spin. The particle's spin and orbital…
Brain activity mapping from MEG data via a hierarchical Bayesian algorithm with automatic depth weighting: sensitivity and specificity analysis
Daniela Calvetti, Annalisa Pascarella, Francesca Pitolli +2
A recently proposed IAS MEG inverse solver algorithm, based on the coupling of a hierarchical Bayesian model with computationally efficient Krylov subspace linear solver, has been…
Position determination and strong field parallax effects for photon emitters in the Schwarzschild spacetime
Donato Bini, Andrea Geralico, Robert T. Jantzen
Position determination of photon emitters and associated strong field parallax effects are investigated using relativistic optics when the photon orbits are confined to the equator…
Gravitational scattering of two black holes at the fourth post-Newtonian approximation
Donato Bini, Thibault Damour
We compute the (center-of-mass frame) scattering angle of hyperboliclike encounters of two spinning black holes, at the fourth post-Newtonian approximation level for orbital ef…
Quantum lattice Boltzmann study of random-mass Dirac fermions in one dimension
Christian B. Mendl, Silvia Palpacelli, Alex Kamenev +1
We study the time evolution of quenched random-mass Dirac fermions in one dimension by quantum lattice Boltzmann simulations. For nonzero noise strength, the diffusion of an initia…
Spin-orbit precession along eccentric orbits for extreme mass ratio black hole binaries and its effective-one-body transcription
Chris Kavanagh, Donato Bini, Thibault Damour +3
In this work we present an analytical gravitational self-force calculation of the spin-orbit precession along an eccentric orbit around a Schwarzschild black hole, following closel…
Isotropic finite-difference discretization of stochastic conservation laws preserving detailed balance
Mahan Raj Banerjee, Sauro Succi, Santosh Ansumali +1
The dynamics of thermally fluctuating conserved order parameters are described by stochastic conservation laws. Thermal equilibrium in such systems requires the dissipative and sto…
Deviation and precession effects in the field of a weak gravitational wave
Donato Bini, Andrea Geralico, Antonello Ortolan
Deviation and precession effects of a bunch of spinning particles in the field of a weak gravitational plane wave are studied according to the Mathisson-Papapetrou-Dixon (MPD) mode…
Kinetic approach to relativistic dissipation
A. Gabbana, M. Mendoza, S. Succi +1
Despite a long record of intense efforts, the basic mechanisms by which dissipation emerges from the microscopic dynamics of a relativistic fluid still elude a complete understandi…
Microscopic and macroscopic models for the onset and progression of Alzheimer's disease
Michiel Bertsch, Bruno Franchi, Maria Carla Tesi +1
In the first part of this paper we review a mathematical model for the onset and progression of Alzheimer's disease (AD) that was developed in subsequent steps over several years.…
Gyroscope precession along general timelike geodesics in a Kerr black hole spacetime
Donato Bini, Andrea Geralico, Robert T. Jantzen
The precession angular velocity of a gyroscope moving along a general geodesic in the Kerr spacetime is analyzed using the geometric properties of the spacetime. Natural frames alo…
Partitioning a macroscopic system into independent subsystems
Luigi Delle Site, Giovanni Ciccotti, Carsten Hartmann
We discuss the problem of partitioning a macroscopic system into a collection of independent subsystems. The partitioning of a system into replica-like subsystems is nowadays a sub…
Relativistic Tidal Acceleration of Astrophysical Jets
Donato Bini, Carmen Chicone, Bahram Mashhoon
Within the framework of general relativity, we investigate the tidal acceleration of astrophysical jets relative to the central collapsed configuration ("Kerr source"). We neglect…

A. Gabbana, M. Mendoza, S. Succi +1
We present a systematic derivation of relativistic lattice kinetic equations for finite-mass particles, reaching close to the zero-mass ultra-relativistic regime treated in the pre…
Copepods encounter rates from a model of escape jump behaviour in turbulence
H. Ardeshiri, F. G. Schmitt, S. Souissi +2
A key ecological parameter for planktonic copepods studies is their interspecies encounter rate which is driven by their behaviour and is strongly influenced by turbulence of the s…
