Atomic Physics for Everyone: An Introduction to Atomic Physics, Quantum Mechanics, and Precision Spectroscopy with No College-Level Prerequisites
Will Raven · Springer · 2025
This open access textbook introduces beginning undergraduate students and high school students to the world of quantum mechanics and atomic spectroscopy. Requiring no previous knowledge of physics and no math beyond basic algebra and sines and cosines, this book focuses on concepts to make the excitement of atomic physics more accessible for learners than ever before. It comes replete with learning goals, exercises and solutions, and an optional experimental component, making this text readily adoptable for both the classroom and the undergraduate lab. The book takes the reader on a lively and engaging tour through topics at the forefront of current science, including photons, quantum numbers, atomic energy levels, some different spectroscopy techniques, electronic structure, atomic notation, angular momentum, hyperfine structure, isotope shifts, the strong force, an introduction to the Standard Model of Particle Physics, and more.

Physical Chemistry
Yingbin Ge · Central Washington University · 2026
This Physical Chemistry textbook by Yingbin Ge is an open-access resource meticulously crafted for undergraduate students in chemistry, biochemistry, and related STEM fields. The text strikes a precise balance between conceptual clarity and mathematical rigor, ensuring students build a deep understanding of thermodynamics, kinetics, quantum chemistry, and statistical mechanics. What sets this text apart is its student-centered pedagogy. Rather than focusing on formalism alone, Ge guides learners through step-by-step derivations that prioritize physical meaning. By explicitly addressing common misconceptions and integrating worked examples, the book transforms complex theory into manageable insights. Its modular structure offers instructors the flexibility to adapt the material to various course sequences, while the accompanying suite of lecture and tutorial videos makes it a comprehensive, accessible solution for the modern classroom.

Semiconductor Physics: Theory and Experiments. With applications to Diode, Light Emitting Diode, Transistor, and Solar Cell
Sven Tougaard · Zenodo · 2023
In 2005, I was asked to give a course in semiconductor physics for physics and engineering students that includes both theory and experiments. I could not find a textbook that met the constraints for the course which was a 4th semester course in semiconductor physics for physics and engineering students some of them with no knowledge of statistical mechanics. Existing textbooks are either too simplistic and do not include a comprehensive physical model description of semiconductors which must include a basic amount of both statistical mechanics, quantum mechanics, and solid-state physics. Alternative textbooks are way too lengthy to fit in a 4th semester course of maximum 5 ECTS length and don’t include experiments. I therefore started to develop a course where only the essential elements of the underlying theory is included. But still keeping the basic physical description of the phenomena at a sober level. So, this is a comprehensive short introductory course and includes both theory and experiments, but it does not substitute for an advanced semiconductor physics course. It is also noted that this course does not include the MOSFET transistor.

COMPUTATIONAL PHYSICS: A Practical Introduction to Computational Physics and Scientific Computing (using C++)
Konstantinosn Anagnostopoulos · National Technical University of Athens · 2016
This book is an introduction to the computational methods used in physics, but also in other scientific fields. It is addressed to an audience that has already been exposed to the introductory level of college physics, usually taught during the first two years of an undergraduate program in science and engineering. It assumes no prior knowledge of numerical analysis, programming or computers and teaches whatever is necessary for the solution of the problems addressed in the text. It can be used as a textbook in introductory computational physics or scientific computing classes. The book starts with very simple problems in particle motion and ends with an in-depth discussion of advanced techniques used in Monte Carlo simulations in statistical mechanics. The level of instruction rises slowly, while discussing problems like the diffusion equation, electrostatics on the plane, quantum mechanics and random walks. All the material can be taught in two semesters, but a selection of topics can form the material of a one semester course. The book aims to provide the students with the background and the experience needed in order to advance to high performance computing projects in science and engineering. It puts emphasis on hands--on programming of numerical code but also on the production, analysis and interpretation of data. But it also tries to keep the students motivated by considering interesting applications in physics, like chaos, quantum mechanics, special relativity and the physics of phase transitions. There is a C++ and a Fortran edition for the core programming. Data analysis is performed using the powerful tools of the GNU/Linux environment. All the necessary software is open source and freely available. The book and the accompanying software are given under a Creative Commons License/GNU public License as a service to the community. It can be used freely as a whole, or any part of it, in any form, by anyone. There is no official distribution of hard copies, b
