Direct comparison of many-body methods for realistic electronic Hamiltonians

Kiel T. Williams, Yuan Yao, Jia Li +22

A large collaboration carefully benchmarks 20 first principles many-body electronic structure methods on a test set of 7 transition metal atoms, and their ions and monoxides. Good…

Accurate many-body electronic structure near the basis set limit: application to the chromium dimer

Junhao Li, Yuan Yao, Adam A. Holmes +4

We describe a method for computing near-exact energies for correlated systems with large Hilbert spaces. The method efficiently identifies the most important basis states (Slater d…

Multireference configuration interaction and perturbation theory without reduced density matrices

Ankit Mahajan, Nick S. Blunt, Iliya Sabzevari +1

The computationally expensive evaluation and storage of high-rank reduced density matrices (RDMs) has been the bottleneck in the calculation of dynamic correlation for multireferen…

An accelerated linear method for optimizing non-linear wavefunctions in variational Monte Carlo

Iliya Sabzevari, Ankit Mahajan, Sandeep Sharma

Although the linear method is one of the most robust algorithms for optimizing non-linearly parametrized wavefunctions in variational Monte Carlo, it suffers from a memory bottlene…

Symmetry projected Jastrow mean field wavefunction in variational Monte Carlo

Ankit Mahajan, Sandeep Sharma

We extend our low-scaling variational Monte Carlo (VMC) algorithm to optimize the symmetry projected Jastrow mean field (SJMF) wavefunctions. These wavefunctions consist of a symme…
