In itinerant systems, electron-electron interactions may lead to the formation of local magnetic moments and their effective exchange coupling, which in turn gives rise to long-range magnetic order. Therefore, when moment formation is weakened, such as in the single-band Hubbard model on a square lattice with the on-site repulsion being randomly switched off on a fraction $x$ of sites, magnetic order is suppressed beyond some critical $x_c$, which was found to lie below the classical… 

Magnetic impurities in a charge-ordered background

We investigate how magnetic impurities may affect a system exhibiting charge-density wave (CDW) in its ground state. We consider a disordered Hubbard-Holstein model with a homogeneous electron-phonon

Ag2S monolayer: an ultrasoft inorganic Lieb lattice.

A silver sulfide (Ag2S) monolayer is reported as a long-sought-after inorganic electronic Lieb lattice, found to be ultrasoft, which enables its electronic properties and topological states near the Fermi level to be finely tuned, as evidenced by the strain-induced topologically non-trivial edge states close to the valence band edge.

Snakes on Lieb lattice

We consider the discrete Allen–Cahn equation with cubic and quintic nonlinearity on the Lieb lattice. We study localized nonlinear solutions of the system that have linear multistability and

The two-dimensional Hubbard model on a square lattice with nearest-neighbor hopping is studied and it is suggested that the system is always paramagnetic, in contradiction with Hartree-Fock predictions.
