A passive atomtronics filter for Fermi gases
Jun Hao Hue, Martin-Isbjörn Trappe, Piotr T. Grochowski +2
We design an atomtronic filter device that spatially separates the components of a two-component Fermi gas with repulsive contact interactions in a two-dimensional geometry. With t…
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…
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…
Energy functionals of single-particle densities: A unified view
Berthold-Georg Englert, Jun Hao Hue, Zi Chao Huang +2
Density functional theory is usually formulated in terms of the density in configuration space. Functionals of the momentum-space density have also been studied, and yet other dens…
Density-potential functional theory for fermions in one dimension
Martin-Isbjörn Trappe, Jun Hao Hue, Berthold-Georg Englert
We showcase the advantages of orbital-free density-potential functional theory (DPFT), a more flexible variant of Hohenberg-Kohn density functional theory. DPFT resolves the usual…
Phase Transitions of Repulsive Two-Component Fermi Gases in Two Dimensions
Martin-Isbjörn Trappe, Piotr T. Grochowski, Jun Hao Hue +2
We predict the phase separations of two-dimensional Fermi gases with repulsive contact-type interactions between two spin components. Using density-potential functional theory with…
Fourth-order leapfrog algorithms for numerical time evolution of classical and quantum systems
Jun Hao Hue, Ege Eren, Shao Hen Chiew +5
Chau et al. [New J. Phys. 20, 073003 (2018)] presented a new and straight-forward derivation of a fourth-order approximation '' of the time-evolution operator and hinted at it…
Systematic corrections to the Thomas-Fermi approximation without a gradient expansion
Thanh Tri Chau, Jun Hao Hue, Martin-Isbjörn Trappe +1
We improve on the Thomas-Fermi approximation for the single-particle density of fermions by introducing inhomogeneity corrections. Rather than invoking a gradient expansion, we rel…
