Bound, unbound operators and the squeezing effect

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

Summary

In this paper we report the difference between the squeezing effect for quadrature operators (describing a photon field or harmonic oscillator) and for spin variables (describing a two-level system), the distinctions coming from the bound and unbound character of the operators involved in the definition of squeezing for each system.
