Neutrino current in a gravitational plane wave collision background
Donato Bini, Christian Cherubini, Gianluca Cruciani +1
The behaviour of a massless Dirac field on a general spacetime background representing two colliding gravitational plane waves is discussed in the Newman-Penrose formalism. The geo…
Transition to hydrodynamics in colliding fermion clouds
F. Toschi, P. Capuzzi, S. Succi +2
We study the transition from the collisionless to the hydrodynamic regime in a two-component spin-polarized mixture of 40K atoms by exciting its dipolar oscillation modes inside ha…
Effects of forcing in three dimensional turbulent flows
Luca Biferale, Alessandra Lanotte, Federico Toschi
We present the results of a numerical investigation of three-dimensional homogeneous and isotropic turbulence, stirred by a random forcing with a power law spectrum, $E_f(k)\sim k^…
Kinetic Theory of Turbulence Modeling: Smallness Parameter, Scaling and Microscopic Derivation of Smagorinsky Model
Santosh Ansumali, Iliya V. Karlin, Sauro Succi
A mean-field approach (filtering out subgrid scales) is applied to the Boltzmann equation in order to derive a subgrid turbulence model based on kinetic theory. It is demonstrated…
Intermittency in Turbulence: computing the scaling exponents in shell models
Roberto Benzi, Luca Biferale, Mauro Sbragaglia +1
We discuss a stochastic closure for the equation of motion satisfied by multi-scale correlation functions in the framework of shell models of turbulence. We give a systematic proce…
The decay of homogeneous anisotropic turbulence
L. Biferale, G. Boffetta, A. Celani +3
We present the results of a numerical investigation of three-dimensional decaying turbulence with statistically homogeneous and anisotropic initial conditions. We show that at larg…
Massless field perturbations and gravitomagnetism in the Kerr-Taub-NUT spacetime
Donato Bini, Christian Cherubini, Robert T. Jantzen +1
A single master equation is given describing spin test fields that are gauge- and tetrad-invariant perturbations of the Kerr-Taub-NUT spacetime representing a source with m…
Gravitomagnetism in the Kerr-Newman-Taub-NUT spacetime
Donato Bini, Christian Cherubini, Robert T. Jantzen +1
We study the motion of test particles and electromagnetic waves in the Kerr-Newman-Taub-NUT spacetime in order to elucidate some of the effects associated with the gravitomagnetic…
