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…
Fractionalized Fermi liquids with the ghost-Gutzwiller Ansatz
Ivan Pasqua, Carlos Mejuto-Zaera, Michele Fabrizio
The paper demonstrates that a fractionalized Fermi liquid (FL*) phase can arise in the single‑band t‑J model using a simple ghost‑Gutzwiller variational Ansatz, producing a tempera…
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…
Ghost Embedding Bridging Chemistry and One-Body Theories
Carlos Mejuto-Zaera, Michele Fabrizio
Phenomenological rules play a central role in the design of chemical reactions and materials with targeted properties. Typically, these are formulated heuristically in terms of non…
Signatures of the Fermi surface reconstruction of a doped Mott insulator in a slab geometry
Gregorio Staffieri, Michele Fabrizio
We investigate a hole-doped Mott insulator in a slab geometry using the dynamical cluster approximation. We show that the enhancement of the correlation strength at the surface res…
How chiral vibrations drive molecular rotation
Ivan Pasqua, Gregorio Staffieri, Michele Fabrizio
We analyze two simple model planar molecules: an ionic molecule with D3 symmetry and a covalent molecule with D6 symmetry. Both symmetries allow the existence of chiral molecular o…
