Coulomb divergence of the high-frequency expansion of the dielectric permittivity

Based on accurate results of the linear response theory and the Kramers-Kronig relations, the permittivity ɛ ( ω ) of the non-relativistic Coulomb system is analyzed at arbitrary thermodynamic parameters in the high-frequency limit ω → ∞ . It is shown that the expansion of the real part of the permi...

Description
Summary:Based on accurate results of the linear response theory and the Kramers-Kronig relations, the permittivity ɛ ( ω ) of the non-relativistic Coulomb system is analyzed at arbitrary thermodynamic parameters in the high-frequency limit ω → ∞ . It is shown that the expansion of the real part of the permittivity Re ɛ ( ω ) in powers of 1 / ω 2 is limited to only three terms. Limit constraints on the power-law behavior of the imaginary part of the permittivity Im ɛ ( ω ) are determined.
