In quantum theory, symmetries are represented by transformations on states and operators.

Symmetry also organizes particle multiplets, selection rules, degeneracies, spontaneous symmetry breaking, and the classification of phases of matter.

'''Symmetry''' is a property of a physical system that remains unchanged under certain transformations. In quantum theory, symmetry principles play a central role in determining the behavior of [[Physics:Quantum fields/field|fields]] and the nature of interactions.

<div style="font-size:90%;">A system exhibits symmetry if it remains unchanged under specific transformations.</div>
</div>

== Description ==
Symmetries describe invariances such as rotations, translations, or internal transformations. In modern physics, they are deeply connected to conservation laws and the structure of interactions.

Gauge theories are based on symmetry principles, where requiring invariance under certain transformations leads to the introduction of [[Physics:Quantum fields/gauge field|gauge fields]].

== Properties ==

* invariance under transformations
* linked to conservation laws
* determines structure of interactions
