Phase separation of a repulsive two-component Fermi gas at the two- to three-dimensional crossover
Piotr T. Grochowski, Martin-Isbjörn Trappe, Tomasz Karpiuk +1
We present a theoretical analysis of phase separations between two repulsively interacting components in an ultracold fermionic gas, occurring at the dimensional crossover in a har…
Single-particle-exact density functional theory
Martin-Isbjörn Trappe, Jun Hao Hue, Jonah Huang Zi Chao +4
We introduce 'single-particle-exact density functional theory' (1pEx-DFT), a novel density functional approach that represents all single-particle contributions to the energy with…
Atoms, dimers, and nanoparticles from orbital-free density-potential functional theory
Martin-Isbjörn Trappe, William C. Witt, Sergei Manzhos
Density-potential functional theory (DPFT) is an alternative formulation of orbital-free density functional theory that may be suitable for modeling the electronic structure of lar…
Contactium: A strongly correlated model system
Jerzy Cioslowski, Berthold-Georg Englert, Martin-Isbjörn Trappe +1
At the limit of an infinite confinement strength , the ground state of a system that comprises two fermions or bosons in a harmonic confinement interacting through the Fermi--Hu…
