reading code i wrote 4 weeks ago and slowly coming to the conclusion i should be given the death penalty

Un evento raro e inimmaginabile per chi segue da anni la vita del vulcano #Etna. Anche gli addetti ai lavori sono rimasti sbalorditi dagli innumerevoli e continui anelli di vapore che si sono sprigionati dal SEC (cratere di sud est) della "signora degli anelli" (foto dal web)

Congratulations to @DavideCianchino for defending his master thesis (woth honors) on the implementation of Cholesky Decomposition for a spin-free Dirac Coulomb relativistic hamiltonian! @MolecolabPisa

CCSD + Cholesky Decomposition + point-group symmetry = CCSD on C60! Check out our new communication on @JChemPhys #compchem #CoupledCluster @T_Nottoli @MolecolabPisa @ChemUniPi pubs.aip.org/aip/jcp/articl…

Can we improve at how we solve linear response equations? After a few decades from the seminal work of Olsen et al., and then Stratmann et al. for DFT, turns out that the answer is yes! @r_alessandro2 @fedepse @T_Nottoli doi.org/10.1021/acs.jc…
