Long-lived excitonic beatings in finite chains under adiabatic motion

Published on 2026-05-08 by Ritesh Pant, Sebastian Wster and Alexander Eisfeld @IOP SCIENCE

Abstract: We investigate transport of a Frenkel exciton in finite one-dimensional chains, where temperature induced interparticle vibrations dynamically modulate the electronic couplings between neighboring particles. In the adiabatic regime, where vibrational motion is slower than excitation transfer between sites, this modulation gives rise to long-lived oscillations in the exciton populations. These oscillations, which we refer to as adiabatic beatings, are most pronounced at the boundaries of the chai[...]


Our summary: This study explores the transport of a Frenkel exciton in finite one-dimensional chains under adiabatic conditions. Long-lived oscillations, termed adiabatic beatings, emerge due to temperature-induced interparticle vibrations modulating electronic couplings. The amplitude of these beatings varies with chain length and particle parity, and they persist even in the presence of disorder.
