Microscopic Emergence of Ancilla Lattice Physics in the Emery Model
MikoÅaj Walicki, Johannes Knolle, Krzysztof Wohlfeld
The paper derives a low‑energy effective theory for the three‑band Emery model on a Lieb lattice, showing how an ancillary lattice emerges and identifying the microscopic condition…

Superconductivity from emergent dipolar interactions in a fractionalized Fermi liquid
Mina-Lou Schleith, Arthur Bril, Nick Bultinck
The paper develops a theory showing how electrons doped into a fractionalized Fermi liquid form spinon‑chargon bound states that interact via a dipolar potential, leading to robust…

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…
