Matrix elements of the Breit Hamiltonian

Physical Review A, 1986
A formulation has been developed for the evaluation of the matrix representation, in sets of \ensuremath{\Vert}${\mathrm{SM}}_{S}$${\mathrm{LM}}_{L}$), \ensuremath{\Vert}${\mathrm{SLJM}}_{J}$), or \ensuremath{\Vert}${\mathrm{JIFM}}_{F}$) functions (as required), of the complete atomic Hamiltonian operator consisting of the electronic, the SL ...

Matrix elements of spin-adapted reduced Hamiltonians

Physical Review A, 1991
General formulas for matrix elements of the pth-order spin-adapted reduced Hamiltonian (p-SRH) are derived based on the theory of generalized reduced density operators. The method is illustrated by a diagrammatic technique developed in detail for p=4.

Generalized Finite Matrix Hamiltonians

American Journal of Physics, 1971
A Fermion representation is developed for truncated Bose operators. The eigenvalue analysis of finite matrix Hamiltonians becomes transparent by using this representation. Renormalization is discussed independent of of infinities for simple separable cases.
