Lecture 8 Relevant sections in text: §1.6 Momentum
... How shall we view momentum in quantum mechanics? Should it be “mass times velocity”, or what? Our approach to the definition of momentum in quantum mechanics will rely on a rather fundamental understanding of what is “momentum”. To motivate our definition, let me remind you that the principal utilit ...

How close can we get waves to wavefunctions, including potential?
... energy of the particle still penetrates the 'wall' to a degree, and why it is necessary to make infinitely strong springs (an infinite potential well), if we want the wavefunction to become zero at the 'wall'. With this, it is a natural question why do typical courses in quantum mechanics still talk ...

... The primeval case of 1 dimensional domain walls, which we are about to discuss in depth, requires a special comment. A domain wall of the type A → B, going from the A to the B ground state, can only be followed (always reading left to right) by an anti-domain wall of the type B → A, and vice versa; ...
