Non-Relativistic Quantum Dynamics

The bulk of known results in spectral and scattering theory for Schrodinger operators has been derived by time-independent (also called stationary) methods, which make extensive use of re­ solvent estimates and the spectral theorem. In very recent years there has been a partial shift of emphasis from the time-indepen­ dent to the time-dependent theory, due to the discovery of new, essentially time...
