Comparison of numerical methods for computing the repeated Compton scattering of photons in isotropic media
Sandeep Kumar Acharya, Jens Chluba, Abir Sarkar
Repeated Compton scattering of photons with thermal electrons is one of the fundamental processes at work in many astrophysical plasma. Solving the exact evolution equations is har…

Dissecting the Compton scattering kernel I: Isotropic media
Abir Sarkar, Jens Chluba, Elizabeth Lee
Compton scattering between electrons and photons plays a crucial role in astrophysical plasmas. Many important aspects of this process can be captured by using the so-called Compto…

Comparison of the full-potential and frozen-core approximation approaches to density-functional calculations of surfaces
Adam Kiejna, Georg Kresse, Jutta Rogal +3
We scrutinize the accuracy of the pseudopotential approximation in density-functional theory (DFT) calculations of surfaces by systematically comparing to results obtained within a…
