Spin multiplicity and entanglement swapping in radical ion recombinations

TL;DR

This paper investigates how spin correlations and their nonlocal swapping affect the relative frequencies of singlet and triplet recombinations in radical ion pairs, concluding that swapping does not influence these frequencies without spin evolution.

Contribution

It introduces a theoretical analysis of spin correlation swapping effects on recombination frequencies, highlighting conditions where swapping has no impact.

Findings

Swapping of spin correlations does not affect recombination frequencies without spin evolution.

The study clarifies the role of nonlocal spin correlation swapping in radical ion recombinations.

Provides a theoretical framework for understanding spin-dependent recombination processes.

Abstract

We address the problem of relative frequencies of singlet and triplet recombinations in a multiparticle system, which consists of spin-correlated radical ion pairs. The nonlocal swapping of spin correlations due to cross-recombinations is taken into account. It is shown that this swapping does not contribute to singlet and triplet recombination frequencies in the absence of spin evolution in the correlated pairs.
