An Introduction to Spontaneous Symmetry Breaking
by Aron J. Beekman, et al.
Publisher: arXiv.org 2019
Number of pages: 149
In these lecture notes, starting from a careful definition of symmetry in physics, we introduce symmetry breaking and its consequences. Emphasis is placed on the physics of singular limits, showing the reality of symmetry breaking even in small-sized systems. Topics covered include Nambu-Goldstone modes, quantum corrections, phase transitions, topological defects and gauge fields. We provide many examples from both high energy and condensed matter physics. These notes are suitable for graduate students.

Modern cosmology has created a tight link between particle physics / field theory and a wealth of new observational data on the structure of the Universe. These notes focus on some aspects concerning the connection between theory and observations.

In these lecture notes the author shall discuss nuclear and particle physics on a somewhat phenomenological level. The mathematical sophistication shall be rather limited, with an emphasis on the physics and on symmetry aspects.

The following notes are the basis for a graduate course. They are oriented towards the application of group theory to particle physics, although some of it can be used for general quantum mechanics. They have no pretense of mathematical rigor.
