Quantum Lyapunov Exponents

Sensitivity to initial conditions in quantum systems is discussed by means of the quantum Lyapunov exponents.As an example, a derivation of the quantum Lyapunov exponent is presented for a Hamiltonian containing a squeezing type nonlinearity. It is argued that quantum exponents can be a suitable tool for studying complicated nonlinear operator equations.
