What Does COHSEX Stand For?

COHSEX stands for Coulomb Hole Plus Screened Exchange Approxn In Band Structure Calcns

COHSEX, which stands for Coulomb Hole Plus Screened Exchange Approximation in Band Structure Calculations, is a method used in computational materials science and condensed matter physics. It enhances the accuracy of electronic structure calculations by effectively addressing the correlations between electrons. By incorporating both the effects of the Coulomb hole and screened exchange interactions, COHSEX provides a more refined description of the electron dynamics in materials, leading to improved predictions of properties such as band gaps and optical responses. This approach is particularly valuable in the study of semiconductors and other correlated materials.
