Charged bosons in a quasi-one-dimensional system

The ground-stare properties of a system of charged bosons in a quasi-one-di mensional model with a neutralizing background are investigated within the hypernetted-chain approximation. Strong correlation effects drive the syste m from a homogeneous fluid phase toward a more ordered structure akin to Wi gner crystallization in higher-dimensional charged quantum systems. The ord ered phase of charged bosons is signaled by the development of a peak in th e static structure factor, which is analyzed as a function of the density a nd the lateral width of the one-dimensional structure. We also calculate th e pair-distribution function, the ground-state energy, and the local-field correction, and compare our results with other theoretical approaches.
