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…
