Typing mathematical expressionsNode id: 225pageRemember: We are using MathJax for mathematical expressions. Text formatting commands of TeX/LaTeX are not supported in MathJax.
Mathematical expressions can be inserted within HTML text of all content types (e.g., page, book page, blog, forum) edited using the available online WYSIWYG HTML editor. The mathematical expressions must be typed using the syntax of TeX/LaTeX.
The easiest way to start is to author a page with some LaTeX code for mathematical expressions given here (based on the code snippets from an online cookbook).
[For a more comprehensive documentation of the TeX commands supported in MathJax, see this document.] |

[NOTES/QM-13006] Boundary condition at a rigid wallNode id: 4750page$\newcommand{\DD}[2][]{\frac{d^2 #1}{d^2 #2}}\newcommand{\matrixelement}[3]{\langle#1|#2|#3\rangle}\newcommand{\PP}[2][]{\frac{\partial^2 #1}{\partial #2^2}}\newcommand{\dd}[2][]{\frac{d#1}{d#2}}\newcommand{\pp}[2][]{\frac{\partial#1}{\partial #2}}\newcommand{\average}[2]{\langle#1|#2|#1\rangle}$
We derive the boundary condition on a rigid wall as a limit of the boundary condition on a the wave function at a point where the potential has a finite jump discontinuity. It is shown that there is no restriction on the derivative of the energy eigenfunction. The only boundary condition is that the eigenfunction must vanish. |

[NOTES/QM-13005] Reflection and Transmission from a PotentialNode id: 6328pageThe reflection and transmission coefficients for a potential problem in one dimension are defined. For this purpose it is sufficient to know the behavior of the wave function at large distances. To set up the problem one needs to impose a suitable boundary condition on the wave function at large distances. It is shown that, for real potentials, the probability conservation implies that the reflection and transmission coefficients add to unity.
