Momentum-resolved fingerprint of Mottness in layer-dimerized Nb3Br8

Momentum-resolved fingerprint of Mottness in layer-dimerized Nb3Br8

Abstract Crystalline solids can become band insulators due to fully filled bands, or Mott insulators due to strong electronic correlations. While Mott insulators can theoretically occur in systems with an even number of electrons per unit cell, distinguishing them from band insulators experimentally...
