Quantum mechanics in one dimension - TCM Group
www.tcm.phy.cam.ac.ukQuantum mechanics in one dimension Following the rules of quantum mechanics, we have seen that the state of a quantum particle, subject to a scalar potential V(r), is described by the time-dependent Schr¨odinger equation, i!∂tΨ(r,t)=HˆΨ(r,t), (2.1) where Hˆ = −!2∇2 2m + V(r) denotes the Hamiltonian. To explore its proper-
Operator methods in quantum mechanics
www.tcm.phy.cam.ac.ukthe quantum mechanics of bound and unbound particles, some properties can not be represented through a wave-like description. For example, the electron spin degree of freedom does not translate to the action of a gradient operator. It is therefore useful to reformulate quantum mechanics in a framework that involves only operators.
