On the Mechanism of Charge Transfer and Electrostatic Field Fluctuations in Disordered Metals

Explore a minimal working model describing disorder-driven fluctuations of electronic charge distributions and electrostatic "Madelung" fields in disordered metals in this 51-minute talk. Delve into the standard perturbative scheme capturing leading contributions from dominant electronic processes, including electrostatic screening and impurity scattering events. Discover how a modest first-order treatment incorporating these effects reproduces linear charge transfer trends in high-entropy and other multicomponent alloys. Gain insights into the microscopic origins of these statistical features. Examine the nature of electronic and Madelung field fluctuations, understanding how they emerge from underlying disorder statistics and can be described using the developed linear response formulation.
