Simultaneous Spin and Point-Group Adaptation in Exact Diagonalization of Spin Clusters
Shadan Ghassemi Tabrizi, Thomas D. Kühne
While either spin or point-group adaptation is straightforward when considered independently, the standard technique for factoring isotropic spin Hamiltonians by the total spin S a…

Projective spin adaptation for the exact diagonalization of isotropic spin clusters
Shadan Ghassemi Tabrizi, Thomas D. Kühne
Spin Hamiltonians, like the Heisenberg model, are used to describe magnetic properties of exchange-coupled molecules and solids. For finite clusters, physical quantities such as he…
