A variational method for integrability-breaking Richardson-Gaudin models
Pieter W. Claeys, Jean-Sébastien Caux, Dimitri Van Neck +1
We present a variational method for approximating the ground state of spin models close to (Richardson-Gaudin) integrability. This is done by variationally optimizing eigenstates o…
Method For Making 2-Electron Response Reduced Density Matrices Approximately N-representable
Caitlin Lanssens, Paul W. Ayers, Dimitri Van Neck +3
In methods like geminal-based approaches or coupled cluster that are solved using the projected Schrödinger equation, direct computation of the 2-electron reduced density matrix (2…
Block product density matrix embedding theory for strongly correlated spin systems
Klaas Gunst, Sebastian Wouters, Stijn De Baerdemacker +1
Density matrix embedding theory (DMET) is a relatively new technique for the calculation of strongly correlated systems. Recently, block product DMET (BPDMET) was introduced for th…
