Many interacting fermions in a one-dimensional harmonic trap: a quantum-chemical treatment
Tomasz Grining, Michał Tomza, Michał Lesiuk +5
We employ \textit{ab initio} methods of quantum chemistry to investigate spin-1/2 fermions interacting via a two-body contact potential in a one-dimensional harmonic trap. The conv…

Calculation of STOs electron repulsion integrals by ellipsoidal expansion and large-order approximations
Michal Lesiuk
For general two-electron two-centre integrals over Slater-type orbitals (STOs), the use of the Neumann expansion for the Coulomb interaction potential yields infinite series in ter…

Crossover between few and many fermions in a harmonic trap
Tomasz Grining, Michał Tomza, Michał Lesiuk +5
The properties of a balanced two-component Fermi gas in a one-dimensional harmonic trap are studied by means of the coupled cluster method. For few fermions we recover the results…
