Symmetry transformations in quantum mechanics

Пребразования симметрии в квантовой механике

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

We introduce a new definition of symmetry transformations in quantum mechanics which contains the textbook definition as a special case. We findseveral conserved quantities associated with one (nonunitary) symmetry transformation. We present two examples.

Riassunto

Si introduce una nuova definizione delle trasformazioni di simmetria in meccanica quantistica che contiene la definizione da manuale come caso speciale. Si trovanodiverse quantità conservate associate a una (non unitaria) trasformazione di simmetria. Si presentano 2 esempi.

Резюме

Мы вводим новое определение преобразований симметрии в квантовой механике, которое содержит обычное определение как частный случай. Мы получаемнесколько сохраняющихся величин, связанных с одним (неунитарным) преобразованием симметрии. В работе рассматриваются два примера.
