    "abstract": "We study the peculiarities of the nonstationary Casimir effect (creation of\nphotons in cavities with moving boundaries) in the special case of two\nresonantly coupled modes with frequencies $\\omega_0$ and $(3\\Delta)\\omega_0$,\nparametrically excited due to small amplitude oscillations of the ideal cavity\nwall at the frequency $2\\omega_0(1\\delta)$ (with $|\\delta|,|\\Delta|\\ll 1$). The\neffects of thermally induced oscillations in time dependences of the mean\nnumbers of created photons and the exchange of quantum purities between the\nmodes are discovered. Squeezing and photon distributions in each modes are\ncalculated for initial vacuum and thermal states. A possibility of compensation\nof detunings is shown.",
