Particles under radiation thrust in Schwarzschild space-time from a flux perpendicular to the equatorial plane
Donato Bini, Andrea Geralico, Robert T. Jantzen +1
Motivated by the picture of a thin accretion disc around a black hole, radiating mainly in the direction perpendicular to its plane, we study the motion of test particles interacti…
Effect of an arbitrary spin orientation on the quadrupolar structure of an extended body in a Schwarzschild spacetime
Donato Bini, Andrea Geralico
The influence of an arbitrary spin orientation on the quadrupolar structure of an extended body moving in a Schwarzschild spacetime is investigated. The body dynamics is described…
Rheological properties of sheared vesicle and cell suspensions
A. Lamura, G. Gompper
Numerical simulations of vesicle suspensions are performed in two dimensions to study their dynamical and rheological properties. An hybrid method is adopted, which combines a meso…
Mesoscopic simulation study of wall roughness effects in micro-channel flows of dense emulsions
Andrea Scagliarini, Mauro Sbragaglia, Massimo Bernaschi
We study the Poiseuille flow of a soft-glassy material above the jamming point, where the material flows like a complex fluid with Herschel- Bulkley rheology. Microscopic plastic r…
Fundamental diagrams in traffic flow: the case of heterogeneous kinetic models
Gabriella Puppo, Matteo Semplice, Andrea Tosin +1
Experimental studies on vehicular traffic provide data on quantities like density, flux, and mean speed of the vehicles. However, the diagrams relating these variables (the fundame…
Highly optimized simulations on single- and multi-GPU systems of 3D Ising spin glass
Matteo Lulli, Massimo Bernaschi, Giorgio Parisi
We present a highly optimized implementation of a Monte Carlo (MC) simulator for the three-dimensional Ising spin-glass model with bimodal disorder, i.e., the 3D Edwards-Anderson m…
Radiation drag in the field of a non-spherical source
Donato Bini, Andrea Geralico, Andrea Passamonti
The motion of a test particle in the gravitational field of a non-spherical source endowed with both mass and mass quadrupole moment is investigated when a test radiation field is…
Rayleigh-Bénard Instability in Graphene
Oliver Furtmaier, Miller Mendoza, Ilya Karlin +2
Motivated by the observation that electrons in graphene, in the hydrodynamic regime of transport, can be treated as a two-dimensional ultra-relativistic gas with very low shear vis…
Tailoring boundary geometry to optimize heat transport in turbulent convection
Srikanth Toppaladoddi, Sauro Succi, John S. Wettlaufer
By tailoring the geometry of the upper boundary in turbulent Rayleigh-Bénard convection we manipulate the boundary layer -- interior flow interaction, and examine the heat transpor…
Gravitational self-force corrections to two-body tidal interactions and the effective one-body formalism
Donato Bini, Thibault Damour
Tidal interactions have a significant influence on the late dynamics of compact binary systems, which constitute the prime targets of the upcoming network of gravitational-wave det…
A level set based method for fixing overhangs in 3D printing
Simone Cacace, Emiliano Cristiani, Leonardo Rocchi
3D printers based on the Fused Decomposition Modeling create objects layer-by-layer dropping fused material. As a consequence, strong overhangs cannot be printed because the new-co…
A destination-preserving model for simulating Wardrop equilibria in traffic flow on networks
Emiliano Cristiani, Fabio S. Priuli
In this paper we propose a LWR-like model for traffic flow on networks which allows one to track several groups of drivers, each of them being characterized only by their destinati…
Refraction index analysis of light propagation in a colliding gravitational wave spacetime
Donato Bini, Andrea Geralico, Maria Haney
The optical medium analogy of a given spacetime was developed decades ago and has since then been widely applied to different gravitational contexts. Here we consider the case of a…

The equatorial motion of extended bodies in a Kerr spacetime is investigated in the framework of the Mathisson-Papapetrou-Dixon model, including the full set of effective component…
Dark energy from cosmological fluids obeying a Shan-Chen non-ideal equation of state
Donato Bini, Andrea Geralico, Daniele Gregoris +1
We consider a Friedmann-Robertson-Walker universe with a fluid source obeying a non-ideal equation of state with "asymptotic freedom," namely ideal gas behavior (pressure changes d…
