Abstract
Thomas Honeychurch studied the effects of periodic driving of voltages for molecules coupled to electrodes. Utilising nonequilibrium Green functions and self-consistent perturbation theory, he analysed the impact of periodic driving on the vibrational modes of the molecules and the current noise, finding increases in both due to driving.
