Electron--electron repulsion, on the one hand, can result in bound pair, which has heavy effective mass. On the other hand, it is also the cause of Mott insulator. We study the effect of a staggered magnetic field on a Hubbard model. We…

Mott insulators can be portrayed as "unsuccessful metals": systems in which a strong Coulomb repulsion prevents charge conduction notwithstanding the metal-like density of conduction electrons. The possibility to unlock such large density…
