Influence of the inter-orbital interaction and kinetic terms on superconductivity: a simple two-orbital Hubbard model
Vito Marino, Diego Florez-Ablan, Luca F. Tocchio +2
We investigate a minimal two-orbital Hubbard model with intra- and inter-orbital nearest-neighbor hopping and , as well as intra- and inter-orbital density-density i…
Emergence of a monopole phase in the Heisenberg model on the triangular lattice for small magnetic fields
Sasank Budaraju, Shi Feng, Josef Willsher +3
The authors use variational Monte Carlo to map the ground‑state phase diagram of the J1‑J2 Heisenberg model on a triangular lattice under small Zeeman fields, revealing a monopole‑…
Triangular - Heisenberg Antiferromagnet in a Magnetic Field
Thomas Bader, Shi Feng, Sasank Budaraju +3
The behavior of the paradigmatic triangular lattice Heisenberg antiferromagnet in a magnetic field remains unsettled despite decades of study. We map out the phase diagra…
A many-body marker for three-dimensional topological insulators with inversion symmetry
Federico Becca, Alberto Parola
We extend the previously defined many-body marker for two-dimensional topological insulators [I. Gilardoni {\it et al.}, Phys. Rev. B {\bf 106}, L161106 (2022)] to d…
Intertwined superconductivity and orbital selectivity in a three-orbital Hubbard model for the iron pnictides
Vito Marino, Alberto Scazzola, Federico Becca +2
We study a three-orbital Hubbard-Kanamori model relevant for iron-based superconductors using variational wave functions explicitly including spatial correlations and electron pair…
Transformer Wave Function for two dimensional frustrated magnets: emergence of a Spin-Liquid Phase in the Shastry-Sutherland Model
Luciano Loris Viteritti, Riccardo Rende, Alberto Parola +2
Understanding quantum magnetism in two-dimensional systems represents a lively branch in modern condensed-matter physics. In the presence of competing super-exchange couplings, mag…
