Incommensurate Phase of a Triangular Frustrated Heisenberg Model Studied via Schwinger-Boson Mean-Field Theory
Peng Li, Haibin Su, Hui-Ning Dong +1
We study a triangular frustrated antiferromagnetic Heisenberg model with nearest-neighbor interaction and third-nearest-neighbor interactions by means of Schwinger-…
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…
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…
