Abstract: We present an analytical approach to solve the wave function and reconstruct the density matrix for a linear x-x coupled oscillator system. The method is available both for weak and strong coupling systems. Employing our method, we analyse the probability distribution function, dynamical recurrence and non-Gaussian entanglement. Including the dissipation, we reconstruct the density matrix in the Liouville-space. Supplying both analytical and numerical treatment, we obtain the steady-state solution of the density matrix and discuss the effect of resonant excitation.
