Energy and Quantum Dynamics
Gennaro Auletta, Shang-Yung Wang
Abstract
In this chapter we shall deal with quantum dynamics and in particular with the basic equation that governs quantum dynamics, the Schro¨dinger equation. We shall consider two of the most important model systems in quantum mechanics: the free particle and the harmonic oscillator. Moreover, we shall deal with the density matrix formalism and composite systems. Another crucial concept that will be introduced here is that of entanglement, a particular manifestation of quantum features.
