We recently extended electronic dynamics to include relativistic effects, such as spin-orbit coupling. These effects are critical when investigating heavy elements and spin phenomena in chemistry. Using our new method, we showed how you can easily obtain the full absorption spectrum for molecules and atoms that includes otherwise spin-forbidden processes. Non-relativistic theories cannot capture these […]

A detailed understanding, with atomistic resolution, of the formation and dynamics of quasiparticles in semiconducting organic polymers is necessary in order to improve their performances. In this context a theoretical-computational approach based on the non-adiabatic excited state Ehrenfest dynamics is appropriate to describe both the formation and the evolution of such quasiparticles. In particular, in […]

Congratulations to David Lingerfelt on passing his general exam and graduating to candidacy. He presented some of his recent work resolving vibronically broadened absorption spectra using Ehrenfest nuclear dynamics (coming soon to a peer-reviewed journal near you).

Einstein’s special relativity in known to measurably affect the time read by clocks on high speed jets, but it influences atomic clocks as well. Indeed, relativistic effects are ubiquitous in chemistry, bringing about the lustrous coloration of gold and the low melting point of mercury. Even more interestingly, relativity produces new magnetic interactions between the […]
