Orbital-free energy functional for electrons in two dimensions
S. Pittalis, E. Rasanen
We derive a non-empirical, orbital-free density functional for the total energy of interacting electrons in two dimensions. The functional consists of a local formula for the inter…

Exact Coulomb cutoff technique for supercell calculations in two dimensions
Alberto Castro, Esa Rasanen, Carlo Andrea Rozzi
We present a reciprocal space technique for the calculation of the Coulomb integral in two dimensions in systems with reduced periodicity, i.e., finite systems, or systems that are…
