Notebooks explaining the VQM packages
In order to use these notebooks, download and install the VQM packages
Plotting complex-valued functions of a real variable. Explains how to fill the space between x-axis and the graph of the absolute value with a color corresponding to the phase. Introduction to the package VQM`ArgColorPlot`. This package was needed to plot all the one-dimensional wave functions in Visual Quantum Mechanics and the spinor-wave functions in Advanced Visual Quantum Mechanics.
Plotting complex-valued functions in two dimensions. Short description of the package VQM`ComplexPlot`. In Visual Quantum Mechanics, this package was used to generate phase-colored density plots of wave functions in two dimensions. Examples are also given in the Mathematica Graphics Gallery and in the Gallery of Complex Functions.
Shows how the package VQM`FastFourier` can be used to compute a numerical approximation of the Fourier transform of a complex function. Explains the ideas and the implementation details of that package in great detail.
Describes the package VQM`Spinors that performs basic operations with two-dimensional complex vectors and Pauli matrices
Shows how to compute a numerical solution of the one-dimensional Schrödinger equation using the package VQM`QuantumKernel`.
Numerical solution of the Schrödinger equation in two dimensions. Introduction to the package VQM`QuantumKernel`. The computations are done using a special application, written in C++ by M. Liebmann. The results are transferred to Mathematica using the MathLink protocol. In Visual Quantum Mechanics, the numerical computations of solutions of the two-dimensional Schrödinger equation have been performed with the help of the package VQM`QuantumKernel`.
