Quantum mechanics
... For time-independent Hamiltonians, the time dependence of the wave functions is known as soon as the eigenenergies En and eigenfunctions φn have been determined. With time dependence taken care of, it makes sense to focus on the Green’s function, which is the Laplace transform of the propagator Z ∞ ...

... effective charge they feel is less than Ze which we can write as Zeffe. If one electron is well outside of the other Z−1 electrons it feels a charge of just 1e (i.e. Zeff = 1). This screening is basically just an application of Gauss’ law The innermost electrons feel nearly the full charge of Ze so ...

Two-particle systems
... This state means that if the spin of one particle is up, then the spin of the other particle must be down. Such state can not be separated into the product state as neither particle is in definite state of being spin up or spin down. Equation (1) above assumes that we can tell which particle is part ...

Linear momentum and the impulse
... Next, we contemplate how to change the value of p for a particle. Obviously, the mass can not change and therefore to change p we must do it by changing v, i.e we must accelerate the particle. Newton’s second law gives Fnet = m dv/dt = d [mv]/dt = dp/dt. This becomes for a system of particles, Fextn ...

4.Operator representations and double phase space
... Are the reflection operators true observables? The parity, +1, or -1, around the origin is an observable wave property. This is currently measured in quantum optics. There, the natural basis are the even and odd states of the Harmonic Oscillator. For reflections around other centres, x, translate t ...

They are ingredients of the models that physicists invent to describe observations. Rather than being restrictions on the behavior of matter, the laws of physics are restrict ...
