Italiano: Figura schematica del modello di Hubbard bidimensionale, dove t è il parametro di salto tra siti del reticolo e U è l'energia repulsiva dovuta alla doppia occupazione di un sito. Le frecce in alto e in basso corrispondono rispettivamente agli elettroni up-spin e down-spin.
English: A schematic figure of the 2-dimensional Hubbard model, where t is the hopping parameter and U is the repulsive energy for double occupation of a site. Up arrows and down arrows correspond to up-spin and down-spin electrons, respectively.
