Extension of Kohn-Sham theory to excited states by means of an off-diagonal density array
Abraham Klein, Reiner M. Dreizler
Early work extending the Kohn-Sham theory to excited states utilized an ensemble average of the Hamiltonian considered as a functional of the corresponding average density. We prop…
Foundations of self-consistent particle-rotor models and of self-consistent cranking models
Abraham Klein
The Kerman-Klein formulation of the equations of motion for a nuclear shell model and its associated variational principle are reviewed briefly. It is then applied to the derivatio…
Application of the Kerman-Klein method to the solution of a spherical shell model for a deformed rare-earth nucleus
Pavlos Protopapas, Abraham Klein
Core-particle coupling models are made viable by assuming that core properties such as matrix elements of multipole and pairing operators and excitation spectra are known independe…
Possible solution of the Coriolis attenuation problem
Pavlos Protopapas, Abraham Klein
The most consistently useful simple model for the study of odd deformed nuclei, the particle-rotor model (strong coupling limit of the core-particle coupling model) has nevertheles…
Derivation and assessment of strong coupling core-particle model from the Kerman-Klein-Dönau-Frauendorf theory
Pavlos Protopapas, Abraham Klein
We review briefly the fundamental equations of a semi-microscopic core-particle coupling method that makes no reference to an intrinsic system of coordinates. We then demonstrate h…
From Heisenberg matrix mechanics to EBK quantization: theory and first applications
Wm. R. Greenberg, Abraham Klein, Ivalyo Zlatev +1
Despite the seminal connection between classical multiply-periodic motion and Heisenberg matrix mechanics and the massive amount of work done on the associated problem of semiclass…
