متن کاملProton spin polarizabilities from polarized Compton scattering
Polarized Compton scattering off the proton is studied within the framework of subtracted dispersion relations for photon energies up to 300 MeV. As a guideline for forthcoming experiments, we focus the attention on the role of the proton’s spin polarizabilities and investigate the most favorable conditions to extract them with a minimum of model dependence. We conclude that a complete separati...
متن کاملQuasilinear spin-voltage profiles in spin thermoelectrics
Recent experiments show that spin thermoelectrics is a promising approach to generate spin voltages. While spin chemical potentials are often limited to a surface layer of the order of the spin-diffusion length, we show that thermoelectrically induced spin chemical potentials can extend much further in itinerant ferromagnets with paramagnetic impurities. In some cases, conservation laws, e.g., ...
متن کاملAtomic Compton Profiles within different exchange-only theories
The Impulse Compton Profiles (CP’s) J(q) and the 〈pn〉− expectation values for some inert gas atoms(He-Kr) are computed and compared within the Harbola-Sahni (HS), Hartree-Fock (HF) theories and a Self Interaction Corrected (SIC) density functional model. The Compton profiles for excited states of Helium atom are also calculated. While the calculated CP’s are found to generally agree, they diffe...
متن کاملQuantum Monte Carlo calculation of Compton profiles of solid lithium
Recent high-resolution Compton scattering experiments in lithium have shown significant discrepancies with conventional band theoretical results. We present a pseudopotential quantum Monte Carlo study of electronelectron and electron-ion correlation effects on the momentum distribution of lithium. We compute the correlation correction to the valence Compton profiles obtained within Kohn-Sham de...
