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…
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…
