Nonlinear electron-lattice (vibronic) dynamics of solids and molecular systems belongs to important unsolved problems in the physics of condensed matter. This work provides an innovative treatment of the vibronic coupling. A theory of electronic transitions with taking into account the quadratic vibronic interaction in multimode systems is developed. An efficient algorithm for calculating the absorption line shapes is presented for the case of strong nonlinear vibronic coupling and arbitrary number of vibrations. Applying the path integral method, the calculation of the spectrum is carried out by means of the eigenvalue problem, where elements of matrices are given by the time-dependent causal pair-correlation functions of configurational c...
