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…
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…
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…
