Jonathan’s paper has been published in JCP! In it we show that in multicomponent OOMP2 the electron-electron correlation can be included after the orbital-optimization procedure with essentially no loss in accuracy for protonic properties relative to the original multicomponent OOMP2 method. Using the results in this paper, we hypothesize that in all multicomponent orbital-optimized methods, it is sufficient to perform the orbital-optimization procedure solely in the presence of electron-proton correlation.

Congratulations to Jonathan for receiving a Barry Goldwater Scholarship!
Jonathan has been named a Barry Goldwater fellow for 2020. Way to go!
New paper in JCTC
Our study on using the heat-bath flavor of selected CI to compute protonic densities of multicomponent systems has been published in JCTC. We are pretty pleased with the results from this study and learned a lot that we hope to follow up on with regards to the need for non HF-orbitals for multicomponent calculations.

New Group Member
A new student, Ethan Lesko, has joined us for the summer. He will be working on benchmarking vibrational configuration interaction techniques that we have been developing over the past year. Welcome Ethan!
