Coupling strength in Coulomb and Yukawa one-component plasmas

Driven one-component plasmas.

A statistical theory is presented that allows the calculation of the stationary state achieved by a driven one-component plasma after a process of collisionless relaxation. The stationary Vlasov equation with appropriate boundary conditions is reduced to an ordinary differential equation, which is then solved numerically. The solution is then compared with the molecular-dynamics simulation. A p...

Practical model for the self-diffusion coefficient in Yukawa one-component plasmas.

A practical physically motivated interpolation formula is presented for the self-diffusion coefficient in Yukawa one-component plasmas that is valid for a wide range of inverse screening lengths and over the entire fluid region.

Caging of particles in one-component plasmas.

Strongly coupled Coulomb systems are characterized by localization ("caging") of particles trapped and oscillating in slowly fluctuating local potential wells. This observation constitutes the basic assumption underlying the quasilocalized charge approximation. Using molecular dynamics simulation we study the changes in the particles' surroundings (cages) in a classical three-dimensional one-co...

Transport coefficients of the Yukawa one-component plasma.

We present equilibrium molecular-dynamics computations of the thermal conductivity and the two viscosities of the Yukawa one-component plasma. The simulations were performed within periodic boundary conditions, and Ewald sums were implemented for the potentials, the forces, and for all the currents which enter the Kubo formulas. For large values of the screening parameter, our estimates of the ...
