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…

Quantifying Gibbs measures of disordered crystals up to the solid-liquid phase transition
Vladislav Efremkin, Julian Heske, Thomas D. Kühne +1
Quantifying the configuration space and the Gibbs measure of thermally disordered condensed matter systems has been a long standing problem. The challenge is to avoid the Gibbs par…
