Dynamical resilience to disorder: The dilute Hubbard model on the Lieb lattice
In this recent article published in Phys. Rev. B, we investigate dilute magnetism in flat band systems, namely in the Hubbard model on a ‘Lieb’ lattice. Interestingly, we show that magnetic order persists to dilutions almost twice as large as the classical percolation threshold for the lattice, thus emphasizing the central role of electron itinerancy to the magnetic response.
Transverse field XY model
We consider the transverse field model on the frustrated diamond chain, considering anisotropic exchange parameters between nearest-neighbor spins. As our key results, we present phase diagrams anisotropy magnetic field at zero temperature, discussing the emergence of phases and their quantum critical points.
