Electron correlation effects and spin-liquid state in the Herbertsmithite Kagome lattice
Sam Azadi, Kühne
We employ real-space variational quantum Monte Carlo methods with resonating valence bond many-body wave functions to investigate electron correlation effects in the Kagome system…
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…
Analytical solutions of symmetric isotropic spin clusters
Shadan Ghassemi Tabrizi, Thomas D. Kühne
Spin models like the Heisenberg Hamiltonian effectively describe the interactions of open-shell transition-metal ions on a lattice and can account for various properties of magneti…
Fourier-Matsubara series expansion for imaginary-time correlation functions
Panagiotis Tolias, Fotios Kalkavouras, Tobias Dornheim
A Fourier-Matsubara series expansion is derived for imaginary-time correlation functions that constitutes the imaginary-time generalization of the infinite Matsubara series for equ…
