Scalable implementations of mean-field and correlation methods based on Lie-algebraic similarity transformation of spin Hamiltonians in the Jordan-Wigner representation
Shadan Ghassemi Tabrizi, Thomas M. Henderson, Thomas D. Kühne +1
Recent work has highlighted that the strong correlation inherent in spin Hamiltonians can be effectively reduced by mapping spins to fermions via the Jordan-Wigner transformation (…

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…
