About the Research
The research project initiated by Prof. Golubev aims to shed light on the fascinating physics behind the interaction of molecules with light. Photoinduced molecular processes play a key role in physics, chemistry, and biology. In nature, light triggers a large variety of chemical reactions such as photosynthesis, vision, and the formation of vitamin D, but also can cause the radiation damage of biomolecules and photolysis. Furthermore, the interaction of light with matter forms the basis of important technological applications such as solar cells in which photoinduced charge transfer and light harvesting are essential.
What all these processes have in common is capturing the energy of light and its transformation into other forms of energy like heat, electricity, or chemical energy. On a microscopic level, this energy conversion process is the result of a correlated motion of electrons and nuclei after photoexcitation or photoionization of a molecule. Although much had been achieved in the understanding of fundamental physics lying behind the electron-nuclear interactions and dynamics, the accurate numerical simulations of light-induced processes taking place in realistic polyatomic molecules remain an unsolved problem.
The objective of this research is to develop both exact and approximate computationally efficient quantum dynamics methods capable of simulating the light-driven electron-nuclear dynamics in polyatomic molecules that take into account non-adiabatic effects and proceeds on the multitude of electronic states. While the main focus will be method development, all new methods will be applied to describe properties and behavior of systems of physical, chemical, and biological interest, interpret recent experimental measurements and guide future experimental efforts.
The proposed research program has the potential to make several scientific breakthroughs that address fundamental questions in atomic and molecular physics and chemistry. The ability to simulate the electronic and nuclear dynamics can provide new insights for understanding properties of matter and is of crucial importance to comprehend the diversity of the world or even life.
