In the past two decades, the density matrix renormalization group (DMRG) has emerged as
an innovative new method in quantum chemistry relying on a theoretical framework very …

Thanks to the high compression of the matrix product state (MPS) form of the wave function
and the efficient site-by-site iterative swee** optimization algorithm, the density matrix …

The implementation of multireference configuration interaction (MRCI) methods in quantum
systems with large active spaces is hindered by the expansion of configuration bases or the …

The quantum chemical version of the density matrix renormalization group (DMRG) method
has established itself as one of the methods of choice for calculations of strongly correlated …

Quantum Monte Carlo (QMC) methods are powerful approaches for solving electronic
structure problems. Although they often provide high-accuracy solutions, the precision of …

Over the last decade, the second-order N-electron valence state perturbation theory
(NEVPT2) has developed into a widely used multireference perturbation method. To apply …

Strong electron correlation can be captured with multireference wave function methods, but
an accurate description of the electronic structure requires accounting for the dynamic …

We report a new implementation of multireference algebraic diagrammatic construction
theory (MR-ADC) for simulations of electron attachment and ionization in strongly correlated …

We introduce the transcorrelated Density Matrix Renormalization Group (tcDMRG) theory for
the efficient approximation of the energy for strongly correlated systems. tcDMRG encodes …

We present a stochastic approach to perform strongly contracted n-electron valence state
perturbation theory (SC-NEVPT), which only requires one-and two-body reduced density …
