- chemps2: Executable to call libchemps2-2 from the command line
chemps2 is a scientific library which contains a spin-adapted

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 4-particle reduced density matrices (2-, 3- and 4-RDM)

of the active space.

.

For general active spaces up to 40 electrons in 40 orbitals can be

handled with DMRG, and for one-dimensional active spaces up to 100

electrons in 100 orbitals. The 2-RDM of these active spaces can

also be easily extracted, while the 3- and 4-RDM 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 DMRG-SCF and DMRG-CASPT2,

respectively. For DMRG-SCF the active space 2-RDM is required, and

for DMRG-CASPT2 the active space 4-RDM.

.

This package installs the executable which parses Hamiltonians in

fcidump format, performs DMRG-SCF and DMRG-CASPT2 calculations as

specified by the user.
