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!

Group Update
It has been a while since we have updated the group website. The most important news to report is that we have welcomed a new graduate student, Muhammad Ardiansyah, into the group! M, as he is known, will be working on improving the generation of training data for fitting quantum neural network potentials and designing new quantum neural network potentials using continuous-filter convolutional neural networks. Welcome, M!
First Post
Thanks to advice from my former postdoc colleague Yang Yang, we now have a website and hosting. As this is my first website since 8th grade (I believe we used Dreamweaver 2.0 and wrote pure HTML back then), website development has changed significantly since my last go at this. I still need to figure out how WordPress works and get the various pages up to date. More updates to come…
