Test particle motion in a gravitational plane wave collision background
Donato Bini, Gianluca Cruciani, Andrea Lunari
Test particle geodesic motion is analysed in detail for the background spacetimes of the degenerate Ferrari-Ibanez colliding gravitational wave solutions. Killing vectors have been…
The ultimate state of thermal convection
Detlef Lohse, Federico Toschi
The ultimate regime of thermal convection, the so called Kraichnan regime (R. H. Kraichnan, Phys. Fluids 5, 1374 (1962)), hitherto has been elusive. Here, numerical evidence for th…
Intermittency in Turbulence: Multiplicative random process in space and time
Roberto Benzi, Luca Biferale, Federico Toschi
We present a simple stochastic algorithm for generating multiplicative processes with multiscaling both in space and in time. With this algorithm we are able to reproduce a synthet…
Galilean-Invariant Lattice-Boltzmann Models with H-Theorem
Bruce M. Boghosian, Peter J. Love, Peter V. Coveney +3
We demonstrate that the requirement of galilean invariance determines the choice of H function for a wide class of entropic lattice Boltzmann models for the incompressible Navier-S…
Dynamics of trapped two-component Fermi gas: temperature dependence of the transition from collisionless to collisional regime
F. Toschi, P. Vignolo, S. Succi +1
We develop a numerical method to study the dynamics of a two-component atomic Fermi gas trapped inside a harmonic potential at temperature T well below the Fermi temperature Tf. We…
Circular holonomy in the Taub-NUT spacetime
Donato Bini, Christian Cherubini, Robert T. Jantzen
Parallel transport around closed circular orbits in the equatorial plane of the Taub-NUT spacetime is analyzed to reveal the effect of the gravitomagnetic monopole parameter on cir…
Regularity Properties of Constrained Set-Valued Mappings
M. Papi, S. Sbaraglia
In these notes, we present a general result concerning the Lipschitz regularity of a certain type of set-valued maps often found in constrained optimization and control problems. T…
Role of the H theorem in lattice Boltzmann hydrodynamic simulations
Sauro Succi, Iliya V. Karlin, Hudong Chen
In the last decade, minimal kinetic models, and primarily the Lattice Boltmann equation, have met with significant success in the simulation of complex hydrodynamic phenomena, rang…
Intermittent permeation of cylindrical nanopores by water
Rosalind Allen, Simone Melchionna, Jean-Pierre Hansen
Molecular Dynamics simulations of water molecules in nanometre sized cylindrical channels connecting two reservoirs show that the permeation of water is very sensitive to the chann…
Teukolsky Master Equation: De Rham wave equation for the gravitational and electromagnetic fields in vacuum
Donato Bini, Christian Cherubini, Robert T Jantzen +1
A new version of the Teukolksy Master Equation, describing any massless field of different spin in the Kerr black hole, is presented here in the form of a wave equa…
Anomalous and dimensional scaling in anisotropic turbulence
L. Biferale, I. Daumont, A. Lanotte +1
We present a numerical study of anisotropic statistical fluctuations in homogeneous turbulent flows. We give an argument to predict the dimensional scaling exponents, (p+j)/3, for…
Explicit finite-difference and direct-simulation-MonteCarlo method for the dynamics of mixed Bose-condensate and cold-atom clouds
P. Vignolo, M. L. Chiofalo, S. Succi +1
We present a new numerical method for studying the dynamics of quantum fluids composed of a Bose-Einstein condensate and a cloud of bosonic or fermionic atoms in a mean-field appro…
