The Adaptive Shift Method in Full Configuration Interaction Quantum Monte Carlo: Development and Applications
Khaldoon Ghanem, Kai Guther, Ali Alavi
In a recent paper, we proposed the adaptive shift method for correcting the undersampling bias of the initiator-FCIQMC. The method allows faster convergence with the number of walk…

Similarity transformation of the electronic Schrödinger equation via Jastrow factorisation
Aron J. Cohen, Hongjun Luo, Kai Guther +3
By expressing the electronic wavefunction in an explicitly-correlated (Jastrow-factorised) form, a similarity-transformed effective Hamiltonian can be derived. The effective Hamilt…
