Abstract
The vacuum excitation and squeezing of two harmonic oscillators with delta kicked interactions for four types of elementary coupling are studied. The exact quantum motion for the Heisenberg operators and the explicit form of squeezing operators are found. The variances are calculated to study the sq ueezing properties for position, momentum and generalized quadrature operat ors.
