Dopant pairing in a disordered magnetic spin ladder
Year: 2025
Type: article
Abstract: I demonstrate a pairing mechanism of dopants in a magnetic lattice, emerging from the underlying of the spins. The effect is demonstrated in a mixed-dimensional model, where dopants travel along a two-leg ladder, while the spins feature Ising interactions along the rungs and the legs of the ladder. The dynamics following the sudden immersion of two nearest neighbor dopants in an infinite temperature spin lattice shows that thermal spin disorder frustrates the relative motion of the dopants and enforces them to copropagate. The predictions are shown to be realistically testable in quantum simulation experiments.
