Interaction picture in the algebraic quantum theory

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

It is shown that in the purely algebraic frame for quantum theory there is a possibility to define the Heisenberg, Schrödinger and interaction picture on the algebra of quasi-local observables. In the different pictures the equations of motion are derived. Some remarks are made concerning the quantum mechanics where the « algebraic frame » can be given explicitly and also checked directly by the usual « Hilbert space approach ».

Riassunto

Si dimostra che nello schema puramente algebrico della teoria quantistica c’è la possibilità di definire le rappresentazioni di Heisenberg, Schrödinger e dell’interazione nell’algebra degli osservabili quasi locali. Si deducono le equazioni del moto nelle diverse rappresentazioni. Si fanno alcuni rilievi sulla meccanica quantistica in cui lo « schema algebrico » può essere dato esplicitamente ed anche verificato direttamente dal solito « accostamento dello spazio hilbertiano ».
