Testing of two-dimensional local approximations in the current-spin and spin-density-functional theories
H. Saarikoski, E. Räsänen, S. Siljamäki +3
We study a model quantum dot system in an external magnetic field by using both the spin-density-functional theory and the current-spin-density-functional theory. The theories are…

First-Principles Calculations of Positron Annihilation in Solids
B. Barbiellini, M. Hakala, R. M. Nieminen +1
We present first-principles approaches based on density functional theory for calculating positron states and annihilation characteristics in condensed matter. The treatment of the…
