Stochastic Tensor Contraction for Efficient MP2 Exchange
Jiace Sun, Garnet Kin-Lic Chan
Second-order Moller--Plesset perturbation theory (MP2) is one of the simplest correlated wave-function methods, but its conventional cost limits its application to large s…
Stochastic tensor contraction for quantum chemistry
Jiace Sun, Garnet Kin-Lic Chan
Many computational methods in ab initio quantum chemistry are formulated in terms of high-order tensor contractions, whose cost determines the size of system that can be studied. W…
Systematic improvement of trial states in phaseless auxiliary-field quantum Monte Carlo
Eirik F. Kjønstad, Yann Damour, Sandeep Sharma +1
We extend the use of coupled cluster (CC) trial states in the phaseless auxiliary-field quantum Monte Carlo (AFQMC) method beyond single and double excitations to include both trip…
Convergence Analysis of the Stochastic Resolution of Identity: Comparing Hutchinson to Hutch++ for the Second-Order Green's Function
Leopoldo Mejía, Sandeep Sharma, Roi Baer +2
Stochastic orbital techniques offer reduced computational scaling and memory requirements to describe ground and excited states at the cost of introducing controlled statistical er…
