Vibrational coherence in electron spin resonance in nanoscale oscillators

TL;DR

This paper explores how electron spin resonance can be used to electrically detect coherent vibrations in nanoscale molecular systems, revealing vibrational modes through inelastic side-band features in the ESR spectrum.

Contribution

It introduces a scheme for electrical detection of vibrational coherence in molecular systems using ESR, highlighting the appearance of vibrational modes as inelastic side-bands.

Findings

Vibrational modes produce inelastic side-band anti-resonances in ESR spectra.

Both equilibrium and non-equilibrium spin- and charge currents are analyzed.

The scheme enables detection of vibrational coherence electrically.

Abstract

We study a scheme for electrical detection, using electron spin resonance, of coherent vibrations in a molecular single electron level trapped near a conduction channel. Both equilibrium spin-currents and non-equilibrium spin- and charge currents are investigated. Inelastic side-band anti-resonances corresponding to the vibrational modes appear in the electron spin resonance spectrum.
