Permutationally Invariant Fourier Series for Molecular Modeling Research Talk at #APSSummit25

Talk on latest work on permutationally invariant Fourier series (PIFSs) and their role in eliminating unphysical energy “holes” in #datadriven #manybody potentials. PIFSs enhance stability and accuracy, pushing the boundaries of what’s possible in CCSD(T)-level #compchem simulations!
