This research aims to enhance mean-field descriptions of strongly correlated spin systems using the Jordan-Wigner transformation.
Developed a self-consistent field scheme to express mean-field energy as a functional of the single-particle density matrix.
Derived the analytical orbital Hessian for diagnosing Hartree-Fock stability.
Calculated ground-state correlation energy using the random-phase approximation.
RPA improved mean-field accuracy, with benchmark results for the XXZ and J1-J2 models on one- and two-dimensional lattices.
Mean-field energy expressed effectively through the new SCF scheme.
