Pinwheel valence-bond-crystal ground state of the spin- Heisenberg antiferromagnet on the lattice
Nikita Astrakhantsev, Francesco Ferrari, Nils Niggemann +9
We investigate the nature of the ground-state of the spin- Heisenberg antiferromagnet on the lattice by complementary state-of-the-art numerical techniques,…
Dimerization tendencies of the pyrochlore Heisenberg antiferromagnet: A functional renormalization group perspective
Max Hering, Vincent Noculak, Francesco Ferrari +2
We investigate the ground state properties of the spin- pyrochlore Heisenberg antiferromagnet using pseudofermion functional renormalization group techniques. The first part o…
Statistical learning of engineered topological phases in the kagome superlattice of AVSb
Thomas Mertz, Paul Wunderlich, Shinibali Bhattacharyya +2
Recent experimental findings have reported the presence of unconventional charge orders in the enlarged () unit-cell of kagome metals AVSb (A=K,Rb,Cs) and hinte…
Gutzwiller-projected states for the - Heisenberg model on the kagome lattice: achievements and pitfalls
Yasir Iqbal, Francesco Ferrari, Aishwarya Chauhan +3
We assess the ground-state phase diagram of the - Heisenberg model on the kagome lattice by employing Gutzwiller-projected fermionic wave functions. Within this framework…
Novel strategies of Ensemble Model Output Statistics (EMOS) for calibrating wind speed/power forecasts
Gabriele Casciaro, Francesco Ferrari, Mattia Cavaiola +1
The issue of the accuracy of wind speed/power forecasts is becoming more and more important as wind power production continues to increase year after year. Having accurate forecast…
Phase diagram of a distorted kagome antiferromagnet and application to Y-kapellasite
Max Hering, Francesco Ferrari, Aleksandar Razpopov +4
We investigate the magnetism of a previously unexplored distorted spin-1/2 kagome model consisting of three symmetry-inequivalent nearest-neighbor antiferromagnetic Heisenberg coup…
Effects of spin-phonon coupling in frustrated Heisenberg models
Francesco Ferrari, Roser Valenti, Federico Becca
The existence and stability of spin-liquid phases represent a central topic in the field of frustrated magnetism. While a few examples of spin-liquid ground states are well establi…
Gapless spin liquids in disguise
Francesco Ferrari, Alberto Parola, Federico Becca
We show that gapless spin liquids, which are potential candidates to describe the ground state of frustrated Heisenberg models in two dimensions, become trivial insulators on cylin…
Towards a Topological Quantum Chemistry description of correlated systems: the case of the Hubbard diamond chain
Mikel Iraola, Niclas Heinsdorf, Apoorv Tiwari +9
The recently introduced topological quantum chemistry (TQC) framework has provided a description of universal topological properties of all possible band insulators in all space gr…
