520 | a We present the derivation and implementation of an efficient matrix-folded formalism for the evaluation of complex response functions at the level of the second-order algebraic-diagrammatic construction ADC(2) scheme. The adopted hybrid MPI/OpenMP parallelization strategy enables the utilization of vast computational resources without significant performance losses as demonstrated by consistent size-scalings for the computationally most demanding steps obtained from calculations of the UV/vis spectra of a guanine oligomer series ranging up to 1,032 contracted basis functions. Further analysis of the convergence behavior of the involved iterative subspace algorithm revealed the superiority of a frequency-separated treatment of response equations even for a large spectral window including 101 frequencies. We demonstrate the applicability to general quantum mechanical operators by the first reported electric circular dichroism spectrum calculated with the complex polarization propagator approach at the ADC(2) level of theory. | |
