The Brorsen group is a computational/theoretical group that seeks to apply and develop new quantum mechanical methods. Our current focus is on multicomponent methods that include nuclear quantum effects in quantum chemistry calculations by not assuming the Born-Oppenheimer approximation for these nuclei. Presently, we are interested in both multireference and many-body multicomponent methods. Other research interests include the development of machine learning-based nonadiabatic dynamics methods, novel applications of selected configuration interaction methods, and the accurate computation of the properties of small molecules relevant to astrochemistry. Please visit our group website for more information.
