Principles of Quantum Mechanics, 2nd ed. - Welcome to SCIPP
scipp.ucsc.edu1 Mathematical Introduction The aim of this book is to provide you with an introduction to quantum mechanics, starting from its axioms. It is the aim of this chapter to equip you with the necessary
The complex logarithm, exponential and power functions
scipp.ucsc.eduwhere the integer Nn is given by: Nn = 1 2 − n 2π Arg z , (16) and [ ] is the greatest integer bracket function introduced in eq. (4). 2. Properties of the real-valued logarithm, exponential and power func-
The SphericalHarmonics - Welcome to SCIPP
scipp.ucsc.edu2. The spherical harmonics In obtaining the solutions to Laplace’s equation in spherical coordinates, it is traditional to introduce the spherical harmonics, Ym ℓ (θ,φ), Ym ℓ (θ,φ) = (−1)m s
Three-Dimensional Rotation Matrices

Eigenvalues and eigenvectors of rotation matrices
scipp.ucsc.eduλ2 − 1 = 0, (12) which yields the eigenvalues, λ = ±1. The interpretation of this result is immediate. The matrix R(θ) when operating on a vector ~v represents a reflection of that vector through a line of reflection that passes through the origin. In the case of λ = 1 we have R(θ)~v = ~v, which means that ~v is a
Regular points and singular points of second-order linear ...
scipp.ucsc.edusecond-order linear differential equation in the case where the origin is an ordinary point of eq. (1). 2. A Frobenius series solution about a regular singular point Consider the homogeneous second-order linear differential equation, x2y′′ +xA(x)y′ +B(x) = 0. (3) We can convert this into the form of eq. (1) by dividing by x2 and identifying
Taylor Series Expansions
scipp.ucsc.eduOf course, if p is a non-negative integer, then the sum in eq. (5) is finite (containing precisely p+1 nonzero terms) and therefore converges trivially for all real values of x, as expected. ∗ Otherwise, the radius of convergence of the binomial series is
Solving the Simple Harmonic Oscillator
scipp.ucsc.eduSolving the Simple Harmonic Oscillator 1. The harmonic oscillator solution: displacement as a function of time We wish to solve the equation of motion for the simple harmonic oscillator: d2x dt2 = − k m x, (1) where k is the spring constant and m is the mass of the oscillating body that is attached to the spring.
