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…
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…
Magnetism in strongly interacting one-dimensional quantum mixtures
Pietro Massignan, Jesper Levinsen, Meera M. Parish
We consider two species of bosons in one dimension near the Tonks-Girardeau limit of infinite interactions. For the case of equal masses and equal intraspecies interactions, the sy…
