Symmetries and symmetry breaking
2017Abstract 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.

AbstractFor the quartic tensor models, the critical point at which the continuum limit is reached corresponds to a phase transition accompanied by a symmetry breaking. This chapter analyzes a simplified quartic tensor model for which the vacuum state in the broken phase can be identified.

Symmetry occurs in many problems in aritifical intelligence. For example, in the n-queens problem, the chessboard can be rotated 90°. As a second example, several machines in a factory might have the same capacity. In a production schedule, we might therefore be able to swap the jobs on machines with the same capacity.
