Coupled oscillators and negative probabilities

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Two Lee-type oscillators are coupled for the purpose of studying, in as elementary a manner as possible, the negative-probability problems occuring in a theory with more than one renormalization constant which may be less than zero. These constants are expressed in terms of variable renormalization parameters and the negative-probability implications for the two lowest, nontrivial subspaces are then analysed.

Riassunto

Si accoppiano due oscillatori del tipo di Lee allo scopo di studiare, nel modo più elementare possibile, i problemi di probabilità negativa che si présentano in una teoria con più di una costante di rinormalizzazione che può essere inferiore a zero. Si esprimono queste costanti in funzione dei parametri di rinormalizzazione variabili e si studiano poi le implicazioni délla probabilità negativa per i due sottospazi inferiori, non banali.
