From Branched Flow to Superwires in Periodic Potentials

Alvar Daza, Eric J. Heller, Anton M. Graf +1

We report unexpected classical and quantum dynamics of a wave propagating in a periodic potential in high Brilloiun zones. Branched flow appears at wavelengths shorter than the typ…

Fundamental gaps of quantum dots on the cheap

Alberto Guandalini, Carlo Andrea Rozzi, Esa Räsänen +1

We show that the fundamental gaps of quantum dots can be accurately estimated at the computational effort of a standard ground-state calculation supplemented with a non self-consis…

Fiend -- Finite Element Quantum Dynamics

Janne Solanpää, Esa Räsänen

We present Fiend - a simulation package for three-dimensional single-particle time-dependent Schrödinger equation for cylindrically symmetric systems. Fiend has been designed for t…

Strictly correlated uniform electron droplets

E. Rasanen, M. Seidl, P. Gori-Giorgi

We study the energetic properties of finite but internally homogeneous D-dimensional electron droplets in the strict-correlation limit. The indirect Coulomb interaction is found to…

Toward an all-round semi-local potential for the electronic exchange

Micael J. T. Oliveira, Esa Räsänen, Stefano Pittalis +1

We test local and semi-local density functionals for the electronic exchange for a variety of systems including atoms, molecules, and atomic chains. In particular, we focus on a re…

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…
