Gausslets, Molecular Hamiltonians, and Tensor Network Methods
Casey Dowdle
We present a demonstration of applying tensor network methods with gausslets as a basis set. The locality of gausslets promotes sparsity in the molecular Hamiltonian, which is important for numerical scaling. We first use Quiqbox.jl to discretize molecular Hamiltonians with gausslets, then use iTensor.jl to approximate the ground-state energies. This pipeline demonstrates the potential of studying the application of novel basis sets for tensor network methods in electronic structure problems.
