About this document

Note by 吳東駿 is a document available to read on EtoBox.

The document discusses symmetries and conservation laws in quantum physics, particularly focusing on conservation of expectation values and the role of the parity operator. It explains the transformation of operators under parity and rotation, as well as the implications of inversion symmetry and selection rules for quantum states. Additionally, it covers the conservation of angular momentum and the conditions for degeneracy in quantum systems.
