Charge densities for conducting ellipsoids [PDF]
European Journal of Physics, 2020 Abstract The volume charge density for a conducting ellipsoid is expressed in simple geometrical terms, and then used to obtain the known surface charge density as well as the uniform charge per length along any principal axis. Corresponding results are presented for conducting hyperellipsoids in any number of spatial dimensions.

Physical Review, 1956 The recent experiments on electron-proton scattering (1) carried out at Stanford have begun to give some insight into the structure of the charge distribution in a physical proton. This distribution of charge is, in the outer regions, probably produced by the cloud of virtual π mesons surrounding the proton.

Raman 2D Peak Line Shape in Epigraphene on SiC
Applied Sciences, 2020 We measured a 2D peak line shape of epitaxial graphene grown on SiC in high vacuum, argon and graphene prepared by hydrogen intercalation from the so called buffer layer on a silicon face of SiC. We fitted the 2D peaks by Lorentzian and Voigt line shapes.

Clinical Case Reports, 2021 Ablation procedures using classical sequential mapping systems may fail to eliminate IAST. The AcQMap dipole charge density mapping technique may offer improved accuracy and has a potential added value for the ultimate success of eliminating IAST.

Charge density wave ratchet [PDF]
Applied Physics Letters, 1999 We propose to operate a locally gated charge density wave as an electron pump. Applying an oscillating gate potential with frequency f causes equally spaced plateaus in the sliding charge density wave current separated by ΔI=2eNf, where N is the number of parallel chains. The effects of thermal noise are investigated.
