Symmetries and symmetry breaking

2017
Abstract The spontaneous breaking of symmetries (SSB) is discussed for global symmetries and Goldstones theorem is derived. The renormalisation of theories with SSB is studied using the effective potential. Then SSB is applied to the Abelian Higgs model, both on the classical and quantum level.

Symmetry and symmetry breaking

2023
This entry begins with a brief description of the historical roots and emergence of the concept of symmetry that is at work in modern science. It then turns to the application of this concept to physics, distinguishing between two different uses of symmetry: symmetry principles versus symmetry arguments.

Symmetries and Breaking of Symmetries

2016
Symmetries help to reduce complexity of calculations. A familiar example is the use of spherical polar coordinates in calculating integrals of quantities which are spherical symmetric. If one manages to find coordinates fitting to symmetries, some of them disappear from the invariant functions and this reduces the calculation task drastically. The same

Skew-Symmetry and Symmetry in the Tensor Algebra

1967
Let E be a vector space and let ⊗ p E be a p-th tensorial power of E, p ≧ 2. Then every permutation σ∈SP*) determines a linear automorphism (also denoted by σ) of ⊗ p E given by $$ \sigma ({x_1} \otimes \cdot \cdot \cdot \otimes {x_p}) = {x_{\sigma {}^{ - 1}(1)}} \otimes \cdot \cdot \cdot \otimes {x_{\sigma {}^{ - 1}(p)}}. $$
