GEM: An implementation of the ghost-Gutzwiller approximation for simulating interacting quantum systems
Samuele Giuli, Tsung-Han Lee, Yong-Xin Yao +6
We present GEM (Ghost Embedding Method), an open-source software package written in Python for computing equilibrium properties of strongly correlated electronic systems within the…
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
Accurately describing a hypothetical symmetry-invariant Mott insulator presents a long-standing ing challenge in iterative quantum embedding methods. We address this issue within t…
Fractionalized Fermi liquids with the ghost-Gutzwiller Ansatz
Ivan Pasqua, Carlos Mejuto-Zaera, Michele Fabrizio
Fractionalized Fermi liquids (), elusive metallic states characterized by fractionalized quasiparticles alongside conventional ones and defying Luttinger's theor…
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…
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…
Fermi-liquid corrections to the intrinsic anomalous Hall conductivity of topological metals
Ivan Pasqua, Michele Fabrizio
We show that topological metals lacking time-reversal symmetry have an intrinsic non-quantized component of the anomalous Hall conductivity which is contributed not only by the Ber…
Exciton condensation driven by bound states of Green's functions zeros
Ivan Pasqua, Andrea Blason, Michele Fabrizio
The interaction driven transition between quantum spin-Hall and Mott insulators in the Bernevig, Hughes and Zhang model is studied by dynamical cluster approximation, and found to…
Luttinger surface dominance and Fermi liquid behaviour of topological Kondo insulators SmB and YbB
Andrea Blason, Ivan Pasqua, Michel Ferrero +1
Defying the traditional classification into metals and insulators, several materials simultaneously display metallic thermal properties and insulating electric behaviour, as if the…
