A BCS state formulation for the fermionic Tonks-Girardeau gas

F Sabater, A Rojo-Francàs, GE Astrakharchik… - arXiv preprint arXiv …, 2024 - arxiv.org
We introduce an alternative expression for the ground state wave function of the fermionic
Tonks-Girardeau gas. Our wave function is constructed based on the occupation numbers …

Radial and angular correlations in a confined system of two atoms in two-dimensional geometry

P Kościk - Quantum Information Processing, 2024 - Springer
We study the ground-state entanglement between two atoms in a two-dimensional isotropic
harmonic trap. We consider a finite-range soft-core interaction that can be applied to …

The fermionic Tonks-Girardeau gas: composite boson formation and a novel formulation of the ground state wave function

F Sabater Garcia - 2024 - diposit.ub.edu
Attractive p-wave one-dimensional fermions are studied in the fermionic Tonks-Girardeau
regime, in which the diagonal properties are shared with those of an ideal Bose gas. We …
