Gravitational scattering at the seventh order in : nonlocal contribution at the sixth post-Newtonian accuracy
Donato Bini, Thibault Damour, Andrea Geralico +2
A recently introduced approach to the classical gravitational dynamics of binary systems involves intricate integrals (linked to a combination of nonlocal-in-time interactions with…
Topological singularities in periodic media: Ginzburg-Landau and core-radius approaches
Roberto Alicandro, Andrea Braides, Marco Cicalese +2
We describe the emergence of topological singularities in periodic media within the Ginzburg-Landau model and the core-radius approach. The energy functionals of both models are de…
Concentrated phase emulsion with multi-core morphology under shear: A numerical study
A. Tiribocchi, A. Montessori, F. Bonaccorso +2
We numerically study the dynamic behavior under a symmetric shear flow of selected examples of concentrated phase emulsions with multi-core morphology confined within a microfluidi…
Inferring urban social networks from publicly available data
Stefano Guarino, Enrico Mastrostefano, Massimo Bernaschi +4
The emergence of social networks and the definition of suitable generative models for synthetic yet realistic social graphs are widely studied problems in the literature. By not be…
Einstein, Planck and Vera Rubin: relevant encounters between the Cosmological and the Quantum Worlds
Paolo Salucci, Giampiero Esposito, Gaetano Lambiase +38
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?, th…
A Lattice Boltzmann Method for Relativistic Rarefied Flows in (2 + 1) Dimensions
Lorenzo Bazzanini, Alessandro Gabbana, Daniele Simeoni +2
We propose an extension to recently developed Relativistic Lattice Boltzmann solvers (RLBM), which allows the simulation of flows close to the free streaming limit. Following previ…
An all-leader agent-based model for turning and flocking birds
Emiliano Cristiani, Marta Menci, Marco Papi +1
Starting from recent experimental observations of starlings and jackdaws, we propose a minimal agent-based mathematical model for bird flocks based on a system of second-order dela…
Chaotic and periodical dynamics of active chiral droplets
Livio Nicola Carenza, Giuseppe Gonnella, Davide Marenduzzo +1
The interplay between the chirality of many biological molecules and the energy injected at small length-scales as the result of biological processes is at the base of the life of…
Discontinuous solutions of Hamilton-Jacobi equations versus Radon measure-valued solutions of scalar conservation laws: Disappearance of singularities
M. Bertsch, F. Smarrazzo, A. Terracina +1
Let be a bounded and Lipschitz continuous function. We consider discontinuous viscosity solutions of the Hamilton-Jacobi equation and signed Radon measure valu…
A Langevin dynamics approach for multi-layer mass transfer problems
Oded Farago, Giuseppe Pontrelli
We use Langevin dynamics simulations to study the mass diffusion problem across two adjacent porous layers of different transport property. At the interface between the layers, we…
Sixth post-Newtonian nonlocal-in-time dynamics of binary systems
Donato Bini, Thibault Damour, Andrea Geralico
We complete our previous derivation, at the sixth post-Newtonian (6PN) accuracy, of the local-in-time dynamics of a gravitationally interacting two-body system by giving two gauge-…
How the growth of ice depends on the fluid dynamics underneath
Ziqi Wang, Enrico Calzavarini, Chao Sun +1
Convective flows coupled with solidification or melting in water bodies play a major role in shaping geophysical landscapes. Particularly in relation to the global climate warming…
