The energy loss of a heavy ion moving in a magnetized strongly coupled electron plasma is considered within the linear response treatment and in high-velocity regime. The analytical expressions for the stopping power have been found for the arbitrary ion incidence angle. The obtained general expression for the stopping power is analyzed for the ion which moves parallel or perpendicular to the magnetic field. It is found that in general the magnetic field and the Coulomb coupling reduce the stopping power as well as the dynamical screening length at high velocities. The influence of the magnetic field and the Coulomb coupling on the high-velocity stopping power is discussed.

“…The approach we use here to construct the dynamic longitudinal conductivity was initiated in the papers [3,4], see also [5] and [1] for a recent review 3 . It was later applied to the investigation of dynamic properties and modes in real one-and two-component plasmas [9,10], binary ionic mixtures [11], binary electronic layers [12], model Coulomb systems [13][14][15][16][17], magnetized plasmas [18][19][20], and the plasma stopping power [21][22][23][24]. In all these applications the Nevanlinna formula (10) (for r = 1) was employed with the parameter function q (k,z) substituted by its static value q (k,0) = ih (k), with the positive parameter h (k) found from an asymptotic value of the distribution density under investigation (the static conductivity, the zero-frequency value of the dynamic structure factor, etc.)…”

A dynamic longitudinal internal conductivity model, derived from the classical method of moments, is applied to the analysis of recent simulation data and reflectivity measurements of shock-compressed dense xenon plasmas. This model satisfies both the non-zero f −sum rule and the second non-zero sum rule, and reproduces the non-monotonicity of the conductivity of dense plasmas beyond the domain of applicability of the Drude-Lorentz model. The Drude-Lorentz model from the point of view of the theory of momentsThe classical model for the (internal) conductivity of dense plasmas and metals,is characterized by two static parameters, the static conductivity σ 0 = σ (ω = 0) = n e e 2 τm −1 = (4π) −1 ω 2 p τ and the relaxation time τ . Here n e is the number density of electrons in the system, −e and m are the electronic charge and mass, and ω p is the plasma frequency.In addition to direct measurements, the static conductivity value can be obtained as [1]Here σ ext (ω) is the external dynamic conductivity of the Coulomb system related to the internal conductivity through the well-known formula 1 [2]:Mathematically, the DL function, σ DL (z), is a simple Nevanlinna (response) function 2 with a single simple pole in the lower half-plane. In addition, the real part of σ DL (z) possesses a single finite frequency moment, which is known also as the f -sum rule:
