Tricritical point in the quantum Hamiltonian mean-field model
Harald Schmid, Johannes Dieplinger, Andrea Solfanelli +2
Engineering long-range interactions in experimental platforms has been achieved with great success in a large variety of quantum systems in recent years. Inspired by this progress,…
Nonlinearity accelerates the thermalization of the quartic FPUT model with stochastic baths
Harald Schmid, Sauro Succi, Stefano Ruffo
We investigate the equilibration process of the strongly coupled quartic Fermi-Pasta-Ulam-Tsingou (FPUT) model by adding Langevin baths to the ends of the chain. The time evolution…
Relativistic antifragility
Sauro Succi
It is shown that the barbell distribution of a gas of relativistic molecules above its critical temperature, can be interpreted as an antifragile response to the relativistic const…
Entropy production in thermal phase separation: a kinetic-theory approach
Yudong Zhang, Aiguo Xu, Guangcai Zhang +3
Entropy production during the process of thermal phase-separation of multiphase flows is investigated by means of a discrete Boltzmann kinetic model. The entropy production rate is…
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…
Ultrarelativistic Transport Coefficients in Two Dimensions
M. Mendoza, I. Karlin, S. Succi +1
We compute the shear and bulk viscosities, as well as the thermal conductivity of an ultrarelativistic fluid obeying the relativistic Boltzmann equation in 2+1 space-time dimension…
Comment on the paper Li-Shi Luo, Wei Liao, Xingwang Chen, Yan Peng and Wei Zhang, Numerics of the lattice Boltzmann method: Effects of collision models on the lattice Boltzmann simulations, Physical Review E 83, 056710 (2011)
I. V. Karlin, S. Succi
Critical comments on the entropic lattice Boltzmann equation (ELBE), by Li-Shi Luo, Wei Liao, Xingwang Chen, Yan Peng and Wei Zhang, Physical Review E 83, 056710 (2011), are based…
Duality in matrix lattice Boltzmann models
R. Adhikari, S. Succi
The notion of duality between the hydrodynamic and kinetic (ghost) variables of lattice kinetic formulations of the Boltzmann equation is introduced. It is suggested that this noti…
Solving the Fokker-Planck kinetic equation on a lattice
Daniele Moroni, Benjamin Rotenberg, Jean-Pierre Hansen +2
We propose a discrete lattice version of the Fokker-Planck kinetic equation along lines similar to the Lattice-Boltzmann scheme. Our work extends an earlier one-dimensional formula…
A note on the lattice Boltzmann method beyond the Chapman Enskog limits
Mauro Sbragaglia, Sauro Succi
A non-perturbative analysis of the Bhatnagar-Gross-Krook (BGK) model kinetic equation for finite values of the Knudsen number is presented. This analysis indicates why discrete kin…
Lattice formulation of the Fokker-Planck equation
S. Melchionna, S. Succi, J. -P. Hansen
A lattice version of the Fokker-Planck equation (FPE), accounting for dissipative interactions, not resolved on the molecular scale, is introduced. The lattice FPE is applied to th…
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…
Entropic Lattice Boltzmann Method for Large Scale Turbulence Simulation
I. V. Karlin, S. Ansumali, E. DE Angelis +2
Recently, a minimal kinetic model for fluid flow, known as entropic lattice Boltzmann method, has been proposed for the simulation of isothermal hydrodynamic flows. At variance wit…
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…
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…
Statistical characterization of the fixed income market efficiency
M. Bernaschi, L. Grilli, L. Marangio +2
We present cross and time series analysis of price fluctuations in the U.S. Treasury fixed income market. By means of techniques borrowed from statistical physics we show that the…
