Bipartite correlations in quantum resonance states
arXiv:1508.02698 · doi:10.1016/j.physleta.2016.01.048
Abstract
We discuss a diagonal representation of a reduced density matrix determined within the framework of the complex scaling method. We also discuss a possible measure of bipartite correlations in quantum resonance states. As an example, we consider a one-dimensional system of two bosons with a contact interaction subjected to an open potential well. The correlation properties of the lowest-energy resonance state of the system are explored over a wide range of the inter-boson interaction strength, including the Tonks-Girardeau regime.
