An adaptive patching method exploits block-sparse QTT structures to reduce computational costs for tensor contractions and enables efficient evaluation of bubble diagrams and Bethe-Salpeter equations.
Parquet theory is formalized for molecules with a static kernel approximation that treats all scattering channels equally and is tested on ionization potentials of small systems.
A CAP-GW method is developed for approximating positions and lifetimes of shape resonances in small molecular anions, validated on N2^-, CO^-, and others with accuracy comparable to wavefunction-based approaches.
NESSi 2.0 reduces nonequilibrium Green's function simulation cost from O(N_t^3) to O(N_t N_c^2) via memory cutoff and adds tools for nonequilibrium steady states relevant to transport and prethermal dynamics.
