Determining Factors for the Accuracy of DMRG in Chemistry
Keywords:Density matrix renormalization group (dmrg), Electron correlation, Quantum chemistry
AbstractThe Density Matrix Renormalization Group (DMRG) algorithm has been a rising star for the accurate ab initio exploration of Born-Oppenheimer potential energy surfaces in theoretical chemistry. However, owing to its iterative numerical nature, pitfalls that can affect the accuracy of DMRG energies need to be circumvented. Here, after a brief introduction into this quantum chemical method, we discuss criteria that determine the accuracy of DMRG calculations.
