New method enables advanced quantum chemistry calculations on consumer GPUs

Researchers have developed a new method for calculating excited-state gradients and nonadiabatic coupling matrix elements (NACMEs) for double-hybrid functionals, achieving higher accuracy than previous methods. This advancement significantly reduces the mean absolute deviation in excitation energies and corrects over-excitation biases. The entire computation, including gradients and NACMEs, can be performed on a consumer-grade GPU like the GeForce RTX 4060, making advanced computational chemistry accessible on commodity hardware.
