Relativistic saturation of Coulomb-induced electron decoherence: from eikonal phase noise to Bethe--Salpeter kinetic theory
Yury A. Budkov
We develop a microscopic theory of the mutual coherence and small-angle scattering of relativistic electron matter waves propagating through a Coulomb-fluctuating medium. Starting…
Localization of a quantum particle in a classical one-component plasma.III. Mutual coherence and coherence degradation in Coulomb-disordered media
Yury A. Budkov
We derive the mutual coherence function of an electron beam propagating through a static or dynamic Coulomb-disordered medium and show that its decay introduces an intrinsic cohere…
Dynamic Coulomb disorder and eikonal attenuation of a quantum particle in a classical one-component plasma
Yury A. Budkov
We extend the static theory of disorder-induced exponential decay of the averaged Green function of a quantum charged particle in a classical one-component plasma to the dynamic re…
Localization of a quantum particle in a classical one-component plasma: fluctuation-induced random potential, localization length and mutual decoherence
Yury A. Budkov
We develop a microscopic theory of disorder-induced attenuation and mutual coherence degradation for a quantum particle in a classical one-component plasma. The random potential or…
Possible Topological Decoherence Transition in Relativistic Electron Beams Propagating through Coulomb-Disordered Media
Yury A. Budkov
We show that the mutual coherence of a relativistic electron beam in a Coulomb-disordered medium is governed by an effective two-dimensional compact phase field with a logarithmic…
