Ground-state correlation properties of charged bosons trapped in strongly anisotropic harmonic potentials

TL;DR

This paper investigates the ground-state correlation properties of a few charged bosons in strongly anisotropic harmonic traps, analyzing how anisotropy influences correlations and comparing quasi-1D systems with strictly 1D limits.

Contribution

It provides a detailed analysis of correlation properties in few-body charged boson systems under anisotropic confinement using the single-mode approximation.

Findings

Correlation entropy varies with anisotropy and interaction strength.

Weak interactions show strong dependence on anisotropy.

Comparison between quasi-1D and strictly 1D systems reveals differences in correlation behavior.

Abstract

We study systems of a few charged bosons contained within a strongly anisotropic harmonic trap. A detailed examination of the ground-state correlation properties of two-, three-, and four-particle systems is carried out within the framework of the single-mode approximation of the transverse components. The linear correlation entropy of the quasi-1D systems is discussed in dependence on the confinement anisotropy and compared with a strictly 1D limit. Only at weak interaction the correlation properties depend strongly on the anisotropy parameter.
