Annihilation rate in positronic systems by quantum Monte Carlo. eLiH as test case
Massimo Mella, Simone Chiesa, Gabriele Morosi
An accurate method to compute the annihilation rate in positronic systems by means of quantum Monte Carlo simulations is tested and compared with previously proposed methods using…
