BAGEL (Brilliantly Advanced General Electronicstructure Library) is a
computational chemistry package aimed at largescale parallel
computations. It specializes on highgly accurate methods and includes
densityfitting and relativistic effects for most of the methods it
implements.
It can compute energies and gradients for the following methods:
 HartreeFock (HF)
 DensityFunctional Theory (DFT)
 Secondorder MoellerPlesset perturbation theory (MP2)
 Complete active space SCF (CASSCF)
 Complete active space second order perturbation theory (CASPT2)
 Extended multistate CASPT2 (XMSCASPT2)
Additionally, it can compute energies for the following methods:
 Configurationinteraction singles (CIS)
 Full configurationinteraction (FCI)
 Multistate internally contracted multireference configurationinteraction
(icMRCI)
 Nelectron valencestate second order perturbation theory (NEVPT2)
 Activespace decomposition (ASD) for dimers and for multiple sites via
density matrix renormalization group (ASDDMRG)
BAGEL is able to optimize stationary geometries and conical intersections and
to compute vibrational frequencies.
BAGEL does not include a disk interface, so computations need to fit in
memory.

chemps2 is a scientific library which contains a spinadapted
implementation of the density matrix renormalization group (DMRG)
for ab initio quantum chemistry. This wavefunction method allows one
to obtain numerical accuracy in active spaces beyond the capabilities
of full configuration interaction (FCI), and allows one to extract
the 2, 3, and 4particle reduced density matrices (2, 3 and 4RDM)
of the active space.
For general active spaces up to 40 electrons in 40 orbitals can be
handled with DMRG, and for onedimensional active spaces up to 100
electrons in 100 orbitals. The 2RDM of these active spaces can
also be easily extracted, while the 3 and 4RDM are limited to
about 28 orbitals.
When the active space size becomes prohibitively expensive for FCI,
DMRG can be used to replace the FCI solver in the complete active
space self consistent field (CASSCF) method and the corresponding
complete active space second order perturbation theory (CASPT2).
The corresponding methods are called DMRGSCF and DMRGCASPT2,
respectively. For DMRGSCF the active space 2RDM is required, and
for DMRGCASPT2 the active space 4RDM.
This package installs the executable which parses Hamiltonians in
fcidump format, performs DMRGSCF and DMRGCASPT2 calculations as
specified by the user.
