摘要
Density functional theory is the workhorse of materials simulations.Unfortunately,the quality of results often varies depending on the specific choice of the exchange-correlation functional,which significantly limits the predictive power of this approach.Coupled cluster theory,including single,double,and perturbative triple particle-hole excitation operators,is widely considered the‘gold standard'of quantum chemistry as it can achieve chemical accuracy for non-strongly correlated applications.Because of the high computational cost,the application of coupled cluster theory in materials simulations is rare,and this is particularly true if finite-temperature properties are of interest for which molecular dynamics simulations have to be performed.
