Group Theory & Physics: Physicist's Textbook

In summary, the physicists' must-have textbook on group theory and its applications to physics includes Wigner's "Group theory and Its Applications to Quantum Mechanics," Tinkham's "Group Theory and Quantum Mechanics," Lax's "Symmetry Principles and Solid State Physics," Joshua's "Symmetry Principles and Magnetic Symmetry in Solid State Physics," and Tung's "Group Theory in Physics." For those interested in high energy physics and relativity theory, Tung's book is recommended, while Lax's book is suitable for solid state physics. The suggested reading order is Joshua, Tinkham, and then Wigner. Other recommended books for particle physicists include Cahn's "Semi-Simple Lie Algebras and their Representations

What is the physicists must have textbook on group theory and its applications to physics?

These books come to mind:

Group theory and Its Applications to Quantum Mechanics, Wigner

Group Theory and Quantum Mechanics, Tinkham

Symmetry Principles and Solid State Physics, Lax

Symmetry Principles and Magnetic Symmetry in Solid State Physics, Joshua

Group Theory in Physics, Tung

Wigner is a classic, hard to read without any prior knowledge. Tungs' book is written in terms of continuous groups which is really helpful for high energy physics and relativity theory. Lax is for solid state and very terse, but readable if you have time.

I would read in this order for Joshua, Tinkham then Wigner. If you understand everything in those unless you are a high energy theorist, you'll know more group theory than you will ever need.

Depending on your background, you might also like:

Cahn, Semi-Simple Lie Algebras and their Representations. It's available free online. http://www-physics.lbl.gov/~rncahn/book.html"

Also Howard Georgi's book of a similar title.

These are oriented towards particle physicists.

FAQ: Group Theory & Physics: Physicist's Textbook

What is group theory?

Group theory is a branch of mathematics that deals with the study of symmetry and structure of objects. It is used to describe the properties and behavior of physical systems, such as particles and waves, and is essential in the field of theoretical physics.

How is group theory applied in physics?

Group theory has a wide range of applications in physics, particularly in quantum mechanics, relativity, and particle physics. It is used to classify elementary particles, describe the symmetries of physical systems, and predict the behavior of complex systems.

What are the fundamental concepts of group theory used in physics?

The fundamental concepts of group theory used in physics include group operations, group representations, and group invariants. Group operations describe how elements of a group interact with each other, while group representations represent these elements as matrices or vectors. Group invariants are quantities that remain unchanged under group transformations.

How does group theory help in understanding the fundamental forces of nature?

Group theory plays a crucial role in understanding the fundamental forces of nature, such as the strong, weak, and electromagnetic forces. It helps in classifying and predicting the properties of elementary particles, which are the building blocks of matter, and in describing the symmetries that govern the interactions between them.

What are some real-life applications of group theory?

Apart from its use in physics, group theory has many real-life applications, including chemistry, crystallography, coding theory, and cryptography. It is also used in computer graphics, robotics, and image processing to recognize patterns and symmetries in data.
