Scattering in 1D,th pictures are in conflict with classical experience and difficult to comprehend. Therefore, one aims for another representation of a free particle that attempts to be in accord with classical experience, namely to have a localization both in position and momentum with the classical position — momentum relationship of a free particle.

Problems in One Dimension,reference books is extremely helpful. In this introductory chapter I discuss the one-dimensional Schrödinger equation in the coordinate space representation. I begin with this topic to permit the non-expert of Maple to make some first steps.

Bound States in 1D,ional (ID) problems even though their usefulness becomes more evident in multi-dimensional many-body problems. To provide some insight into what it takes for a wavefunction to be an eigenfunction of a differential operator I discuss the idea of a local energy density in some detail.

Alternatively, one can define free position eigenstates .(.) = .(. — ..) that describe a free particle located at .., but whose momentum is completely undetermined. Bo

Problems in 3D,he eigenvalues for some examples. Angular momentum plays an important role in QM. In classical mechanics the angular momentum vector 1 = r × p of a point particle moving in a central potential .(.) is conserved, which implies that the motion is confined to a plane. In QM the angular momentum operato

Spin and Time-Dependent Processes,pin degree of freedom is added for spin-1/2 particles. A fully satisfying description of fermions is only possible in the context of relativistic QM. Nevertheless, if one accepts the construction of the Pauli equation, many relevant results can be calculated with it.
