Random phase approximation with exchange for an accurate description of crystalline polymorphism

We determine the correlation energy of BN, SiO_{2}, and ice polymorphs employing a recently developed random phase approximation with exchange (RPAx) approach. The RPAx provides larger and more accurate polarizabilities as compared to the random phase approximation (RPA), and captures the effects of...
