Orbital angular momentum
Orbital angular momentum

... We construct the operators and the eigenfunctions of orbital angular momentum, L = r × p, in the Hilbert space of position eigenstates. Then the usual differential operator for p can be used. Under the scaling r → ξr, one has p → p/ξ, so that L is independent of the scale of the radius, ξ. Hence in ...

... Dialectical symmetry of polar properties of the Universe is a result of the formation of the Universe as Being from Non-Being with the zero measure. From the metaphysical point of view Non-Being is merely a mathematical emptiness, whereas from dialectical point of view Non-Being is another existence ...

... This projection is a fibration with fiber π −1 (z) = Yz . We define a vector bundle H1twist (Y /X) over X whose fiber at z is the twisted homology group H1twist (Yz ). An element Cz0 ∈ H1twist (Yz0 ) naturally defines a twisted cycle in every fiber H1twist (Yz ) if z is sufficiently close to z0 . Such local ...


... appendix. By choosing different elementary functions in the identity (4), we are led to a large class of interesting new identities involving higher-order derivatives of scalar functions. Moreover, specializing the resulting derivative identities to various elementary types of functions u(x), leads ...

... identify N̂ with Jz , â with J+ and â with J− . In the oscillator case we learned from these that, acting on states, ↠raises the N̂ eigenvalue by one unit while â decreases it by one unit. As we will see, Jˆ+ adds ~ to the Jˆz eigenvalue and Jˆ− subtracts ~ to the Jˆz eigenvalue. Since J2 and ...

... In these lecture notes I will discuss the solution of the time-independent Schrödinger equation for the hydrogen atom. The hydrogen atom is the simplest atom and can be solved exactly. It is a useful model for all other atoms. The S.E. for the hydrogen atom can be reduced to a ony-body problem in th ...

... lifting a degeneracy. The idea is closely related to the discussion at the end of example 3–33. If you comprehend the idea behind that discussion, you have the basic principle of this discussion. Also, “complete” here means all possiblities are clear, i.e., that any degeneracy is removed. This is th ...

We assume that the wave functions of nuclei are eigenstates of a Schréodinger equation for bound systems of identical fermions. The starting point of a mathematicall ...

... This means that it is possible to obtain solutions to Schrödinger equation (Equation 60) which are common eigenfunctions of Ĥ, L2 and Lz . We already know simultaneous eigenfunctions of L2 and Lz : these are of course the spherical harmonics, Ylm (θ, φ). Thus, a full solution to Schrödinger equat ...

We evaluate the time-dependent frequency of each harmonic by windowing its spectrum and transforming to the time domain [12]. We find that each harmonic exhibits a sing ...
