icmpspt — Internal-contracted MPS perturbation method¶
icmpspt module is an interface to a multi-reference perturbation method that uses DMRG (MPS) wavefunctions as the zeroth order wavefunction. The DMRG wavefunction needs to be generated using the
dmrgscf solver. The ic-MPSPT solver can be obtained from Sandeep Sharma (firstname.lastname@example.org).
