Kramers pseudospin and the quantum number proposed for the many-electron Dirac?Coulomb Hamiltonian
Shadan Ghassemi Tabrizi
The square of a sum of single-electron time reversals has been proposed as a conserved quantity with an integer eigenvalue spectrum for the many-electron Dirac-Coulomb Hamiltonian…
Systematic extinctions in inelastic neutron scattering from molecular spin clusters
Shadan Ghassemi Tabrizi
Inelastic neutron scattering on a single crystal resolves how the intensity of a magnetic transition of a molecular spin cluster varies with the momentum-transfer vector $\mathbf{Q…
Hidden symmetry at the diabolical points of a biaxial spin
Shadan Ghassemi Tabrizi
In a rotated frame the biaxial spin Hamiltonian is a finite tight-binding chain whose hopping amplitudes are tuned by the applied fiel…
GPU-accelerated finite-temperature Lanczos method for Heisenberg spin systems with non-Abelian permutation symmetries
Shadan Ghassemi Tabrizi, Thomas D. Kühne
We extend a recent GPU implementation of the finite-temperature Lanczos method (FTLM) for Heisenberg spin Hamiltonians, which uses only total-magnetization symmetry, to the full pe…
GPU-accelerated finite-temperature Lanczos method for spin Hamiltonians
Shadan Ghassemi Tabrizi, Thomas D. Kühne
We present a GPU implementation of the finite-temperature Lanczos method (FTLM) for Heisenberg spin Hamiltonians that targets workstation hardware rather than distributed-memory cl…
SCF framework, HF stability and RPA correlation for Jordan-Wigner-transformed spin Hamiltonians on arbitrary coupling topologies
Shadan Ghassemi Tabrizi, Thomas M. Henderson, Thomas D. Kühne +1
Mapping spins to fermions via the Jordan-Wigner (JW) transformation can render mean-field (Hartree-Fock, HF) descriptions effective for strongly correlated spin systems. As establi…
