Direct minimization versus iterative embedding in the ghost-Gutzwiller method: a comparative study of magnetism in Mott insulators
Antonio Maria Tagliente, Ivan Pasqua, Michele Fabrizio
The paper compares two ways of solving the ghost‑Gutzwiller method—iterative embedding and direct energy minimization—showing that the iterative approach is efficient but can fail…
Band structure picture for topology in strongly correlated systems with the ghost Gutzwiller ansatz
Ivan Pasqua, Antonio Maria Tagliente, Gabriele Bellomia +3
Understanding the interplay between electronic correlations and band topology remains a central challenge in condensed matter physics, primarily hindered by a language mismatch pro…
Revealing spinons by proximity effect
Antonio Maria Tagliente, Carlos Mejuto-Zaera, Michele Fabrizio
The ghost-Gutzwiller variational wavefunction within the Gutzwiller approximation is shown to stabilize a genuine paramagnetic Mott insulator in the half-filled single-band Hubbard…
