In questo libro si espongono in dettaglio le basi matematiche per la meccanica quantistica. Gli argomenti principali sono: spazio dei ket e dei bra e loro proprietà e operazioni, prodotto interno tra ket e bra, norma, ortogonalità , operatori e loro operazioni, operazioni degli operatori sui ket come misura di un'osservabile per uno stato fisico, operatore aggiunto, operatori hermitiani, operatori unitari, prodotto esterno, basi di autoket. Autore: dott. Alessio Mangoni, fisico teorico.

Un operatore X è detto hermitiano (o autoaggiunto) se coincide con il suo aggiunto, ovvero se

Un operatore hermitiano ha importanti proprietà e sono il tipo di operatori usati in meccanica quantistica. Innanzitutto gli autovalori di un operatore hermitiano sono numeri reali e gli autoket corrispondenti a distinti autovalori sono ortogonali. Infatti dato un operatore hermitiano X, se

sono gli autovalori e

gli autoket possiamo scrivere
