An algorithm for obtaining an optimalized projected Hamiltonian and its groundstate

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

An algorithm is proposed for solving the problem of projecting the Hamiltonian onto a finite dimensional subspace in such a way that the groundstate of the projected Hamiltonian represents an optimalized approximation to the groundstate of the full (unprojected) Hamiltonian and simultaneously for obtaining the groundstate of the projected Hamiltonian.
