Real-time quantum dynamics of interacting electrons: self-organized nanoscale structure in a spin-electron coupled system.
We investigate the quantum evolution of the excited electronic states combined with the classical dynamics of the order parameter field in a spin-electron coupled system. It is found that the nanoscale spatial structure of the spins evolves spontaneously accompanied by the localization of the electronic wave functions, and the nonadiabatic quantum transitions through a resonant mutual precession analogous to the electron spin resonance (ESR) process.
