The Bravaya research group investigates challenging electronic structure phenomena in biomolecules and systems relevant for materials, which include photoinduced processes, autoionizing electronic states, and magnetic field effects. To this end, we use and develop high-level electronic structure methods targeting processes involving multiple electronic states, chemistry of open-shell species in magnetic fields, and electronically excited and metastable systems.

Autoionizing electronic states – Electronic states metastable with respect to electron detachment are Scientific Image -2ubiquitous in highly energetic environment, are common as excited states of anions, and play important role in condensed phases processes, e.g. DNA damage by secondary electrons. We develop methods combining accurate electronic structure techniques (for example EOM-CC) and theories for description of resonances position and lifetimes (complex scaling and complex-absorbing potential).

Avian birds magnetoreception (electronic structure of cryptochromes) – Cryptochromes are a diverse class of flavoproteins involved in a variety of biological processes, e.g. circadian clock regulation, Scientific Image -1phototropism. An intriguing question concerning these protoreceptors is their possible involvement in a light-dependent magnetoreception in insects and animals. Using computational chemistry tools we will explore the mechanism of cryptochromes photoactivation and analyze the effect of the Earth’s magnetic field on their photophysics. To this aim, we are interested in developing ab initio techniques for perturbative treatment of spin-spin, spin-orbit, and hyperfine interactions based on the EOM-CC family of methods.
