Article

Summary

The coupled parametric quantum oscillators are discussed. The ground, coherent states and integrals of motion for the parametric chain with time-dependent frequencies are constructed. The possibility of controlling in principle the dispersions of coordinates and momenta is suggested. The squeezing coefficients in coherent states are found.
