Pinning effect and QPT-like behavior for two particles confined by a core-shell potential
Pier Paolo Marchisio, Jeremy P. Coe, Irene D'Amico
We study the ground state entanglement, energy and fidelities of a two-electron system bounded by a core-shell potential, where the core width is varied continuously until it event…
The entanglement of few-particle systems when using the local-density approximation
J. P. Coe, I. D'Amico
In this chapter we discuss methods to calculate the entanglement of a system using density-functional theory. We firstly introduce density-functional theory and the local-density a…
Exact and LDA entanglement of tailored densities in an interacting one-dimensional electron system
J. P. Coe, I. D'Amico
We calculate the `exact' potential corresponding to a one-dimensional interacting system of two electrons with a specific, tailored density. We use one-dimensional density-function…
Reverse engineering in many-body quantum physics: What many-body system corresponds to an effective single-particle equation?
J. P. Coe, K. Capelle, I. D'Amico
The mapping, exact or approximate, of a many-body problem onto an effective single-body problem is one of the most widely used conceptual and computational tools of physics. Here,…
