Quantum Theory for Chemical Applications (QTCA)


Quantum Theory for Chemical Applications (QTCA), published by Oxford University Press, New York, NY (2020), is a comprehensive quantum theory textbook. QTCA was written for beginners as well as for more experienced students and also for practicing researchers who are working in fields related to chemistry. See this URL for a table of contents and other information about the text, and for ordering information. The book is also available from other sellers.

Please view this errata sheet (PDF) for corrections relative to the first print run of QTCA (late 2020/early 2021). The list will be updated whenever a typographic error or another mistake is found.

Supplementary Material for QTCA

Below, there is a slowly growing list of notebooks in the Wolfram computational language (aka Mathematica syntax) for download. I (Jochen) used Mathematica extensively to create visualizations of quantum mechanics concepts, to illustrate them in QTCA and other publications. I plan to make a range of notebooks available here, covering material across the chapters of QTCA, so that students and course instructors can explore some of the visualizations interactively.

The notebooks (file extension .nb) can be viewed with Mathematica, of course, but also with the free Wolfram Player. Mathematica is not free software, but many colleges have campus licenses, which means that students and instructors can use it without having to pay for an individual license. The Wolfram Player is free for download, runs on Windows, Mac, and Linux operating systems, and it will faithfully reproduce the visualizations and their interactive features. The main drawback of using the Player is that you won’t be able to modify the underlying code easily.

Note: Visualization functionality was confirmed to work with Mathematica and Wolfram Player versions 13.0 and 13.3, and very likely the software works also with any of the release 12 and 14+ versions. Mathematica and Wolfram Player version 13.1 have a bug and will not produce correct images. Versions 13.2 might produce images that appear as if they were based on low-resolution data.
