Quantum correlations and degeneracy of identical bosons in a two-dimensional harmonic trap
Quantum correlations and degeneracy of identical bosons in a two-dimensional harmonic trap
We consider a few number of identical bosons trapped in a 2D isotropic harmonic potential and also the $N$-boson system when it is feasible. The atom-atom interaction is modelled by means of a finite-range Gaussian interaction. The spectral properties of the system are scrutinized, in particular, we derive analytic expressions …
