Contribution

It introduces a novel interpretation of charge pairing as quantum entanglement and analyzes the impact of superposition states and entropic Coulomb forces in these systems.

Findings

Charge pairing is driven by quantum entanglement.

Superposition states induce entanglement between particles.

Entropic Coulomb force correction influences charge pairing.

Abstract

Various charge pairings in strongly correlated electron systems are interpreted as quantum entanglement of a composite system. Particles in the intermediate phase have a tendency to form the coherent superposition state of the localized state and the itinerant state, which induces the entanglement of both particles in the bipartite subsystems for increasing the entropy of the system. The correction to the entropic Coulomb force becomes an immediate cause of charge pairing.
