Density Matrix Renormalization Group Pair-Density Functional Theory (DMRG-PDFT): Singlet-Triplet Gaps in Polyacenes and Polyacetylenes
Prachi Sharma, Varinia Bernales, Stefan Knecht +2
The density matrix renormalization group (DMRG) is a powerful method to treat static correlation. Here we present an inexpensive way to add additional dynamic correlation energy to…

Dynamical susceptibility of a Fermi liquid
Vladimir A. Zyuzin, Prachi Sharma, Dmitrii L. Maslov
We study the dynamic response of a Fermi liquid in the spin, charge and nematic channels beyond the random phase approximation for the dynamically screened Coulomb potential. In al…
