Identifying transition states often requires hundreds/thousands of ab initio calculations. We report a more efficient route by finding the shortest path (“geodesic”) between reactant and product on a machine-learned potential energy surface, without any ab initio calculations.

Excited to share @mtzlab 's venture into periodic quantum chemistry. All-electron hybrid DFT on unit cells with hundreds (or few thousands) of atoms in the timescale of hours, with quadratic scaling vs system size. GPUs Gaussian orbitals ftw. #compchem arxiv.org/abs/2410.22278

Our contribution to the cyclobutanone photochemistry prediction challenge has been published @JChemPhys. Using EOM-CCSD & TDDFT with ab-initio multiple spawning, we estimate a few ps lifetime for the S2 state, leading to relatively slow photodissociation. doi.org/10.1063/5.0203800

Our new article in @JCIM_JCTC, led by Andreas Hillers-Bendtsen, presents a new strategy for achieving quartic computational scaling of coupled cluster ground-state energies, by using tensor hypercontraction (THC) in cluster perturbation theory. doi.org/10.1021/acs.jctc.3c0…

Tensor Hypercontraction of Cluster Perturbation Theory: Quartic Scaling Perturbation Series for the...

Even though cluster perturbation theory has been shown to be a robust noniterative alternative to coupled cluster theory, it is still plagued by high order polynomial computational scaling and the...

My first paper as a postdoc in @mtzlab just came out in @JCIM_JCTC. We wondered how well standard quantum chemistry can compute the XAS of ozone (prototypical biradicaloid) and found that orbital optimized DFT (i.e. ROKS) gives excellent results. #compchem pubs.acs.org/doi/10.1021/acs…
