Role of Berry Forces in Nonadiabatic Dynamics and Implications for Spintronics
Joe SubotnikUniversity of Pennsylvania - Department of Chemistry
Chemists and physicists have studied electron transfer for a long time, thinking about how molecules and materials dissipate electronic energy through vibrational channels, how phonon modes can both provide and accept quanta to enhance relaxation, and how entropy is produced until equilibrium is eventually reached. Recently, the suggestion has been made that nonadiabatic effects may also be responsible for a host of cutting-edge experiments involving spin separation at room temperature in the condensed phase. Here, I will address our fundamental understanding of coupled nuclear-electronic motion in the presence of spin-orbit coupling, I will discuss the role played by large voltages and Berry force, and I will highlight a set of very exciting questions that are emerging at the intersection of spintronics and molecular dynamics.
