The von Neumann entanglement entropy for Wigner-crystal states in one dimensional N-particle systems
Przemyslaw Koscik
We study one-dimensional systems of particles in a one-dimensional harmonic trap with an inverse power law interaction . Within the framework of the harmonic appr…

Bipartite correlations in quantum resonance states
Przemyslaw Koscik
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 corr…

Entanglement in helium atom confined in an impenetrable cavity
Przemyslaw Koscik, Jayanta K. Saha
We explore ground-state entanglement properties of helium atom confined at the center of an impenetrable spherical cavity of varying radius by using explicitly correlated Hylleraas…
