Local field effects on the radiative lifetimes of Ce in different hosts
Chang-Kui Duan, Michael F. Reid
For emitters embedded in media of various refractive indices, different theoretical models predicted substantially different dependencies of the spontaneous emission lifetime on re…
Simplified diagrammatic expansion for effective operator
Chang-Kui Duan, Yungui Gong, Hui-Ning Dong +1
For a quantum many-body problem, effective Hamiltonians that give exact eigenvalues in reduced model space usually have different expressions, diagrams and evaluation rules from ef…
Dependence of spontaneous emission rates of emitters on the refractive index of the surrounding medial
Chang-Kui Duan, Michael F. Reid
For emitters in a medium, different macroscopic or microscopic theoretical models predict substantially different dependencies of the spontaneous emission lifetime on refractive in…
Conservation of connectivity of model-space effective interactions under a class of similarity transformation
Chang-Kui Duan, Yungui Gong, Hui-Ning Dong +1
Effective interaction operators usually act on a restricted model space and give the same energies (for Hamiltonian) and matrix elements (for transition operators etc.) as those of…
Calculation of single-beam two-photon absorption transition rate of rare-earth ions using effective operator and diagrammatic representation
Chang-Kui Duan, Michael F. Reid, Gang Ruan +1
Effective operators needed in single-beam two-photon transition calculations have been represented with modified Goldstone diagrams similar to the type suggested by Duan and co-wor…
Calculation of single-beam two-photon absorption rate of lanthanides: effective operator method and perturbative expansion
Chang-Kui Duan, Gang Ruan, Michael F. Reid
Perturbative contributions to single-beam two-photon transition rates may be divided into two types. The first, involving low-energy intermediate states, require a high-order pertu…
