Magnetic phases of the anisotropic triangular Hubbard model from the ghost-Gutzwiller approximation in the rotating spin-frame
Azin Kazemi-Moridani, Samuele Giuli, Tsung-Han Lee +4
We investigate the magnetic phase diagram of the half-filled Hubbard model on the anisotropic triangular lattice using the Gutzwiller approximation (GA) and its ghost generalizatio…
Unifying Variational and Dynamical Quantum Embedding: From Ghost Gutzwiller Approximation to Dynamical Mean-Field Theory
Samuele Giuli, Tsung-Han Lee, Yong-Xin Yao +4
Dynamical and variational frameworks have long been viewed as distinct paradigms. In particular, in quantum embedding (QE) frameworks, dynamical mean-field theory (DMFT) captures n…
More is uncorrelated: Tuning the local correlations of SU() Fermi-Hubbard systems via controlled symmetry breaking
Edoardo Zavatti, Gabriele Bellomia, Matteo Ferraretto +2
Cold-atom experiments based on alkali-like atoms provide us with a tool to experimentally realize Hubbard models with a large number of components. The value of can be seen…
Enhanced coherence and layer-selective charge order in a trilayer cuprate superconductor
S. Smit, M. Bluschke, P. Moen +25
Trilayer cuprates hold the record for the highest superconducting critical temperatures (), yet the underlying mechanism remains elusive. Using time- and angle-resolv…
Next-generation EDIpack: A Lanczos-based package for quantum impurity models featuring general broken-symmetry phases, flexible bath topologies and multi-platform interoperability
Lorenzo Crippa, Igor Krivenko, Samuele Giuli +10
We present a next-generation version of EDIpack, a flexible, high-performance numerical library using Lanczos-based exact diagonalization to solve generic quantum impurity problems…
Altermagnetism from interaction-driven itinerant magnetism
Samuele Giuli, Carlos Mejuto-Zaera, Massimo Capone
Altermagnetism, a new phase of collinear spin-order sharing similarities with antiferromagnets and ferromagnets, has introduced a new guiding principle for spintronic/thermoelectri…
