Announcements of conferences, workshops, schools…
Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

Energy functionals of the Green's function can provide simultaneously spectral and thermodynamic properties of interacting electrons' systems. In this work, exploiting a localized-GW approach, we introduce an approximation to the exchange-correlation part of the Klein functional that generalizes the energy functional of DFT+U to host a dynamical screened potential U(ω). Furthermore, we solve exactly the resulting Dyson equation extending to crystals the algorithmic-inversion method. To demonstrate the approach we compute the spectral, thermodynamic, and vibrational properties of SrVO3, finding results in excellent agreement with experiments and state-of-the-art computational methods, and overall at a negligible computational cost.
