What is the role of parity in quantum mechanics?

Click For Summary
SUMMARY

Parity in quantum mechanics refers to the symmetry of physical systems under spatial inversion, where coordinates transform as x -> -x, y -> -y, z -> -z. If an object or equation remains unchanged after this transformation, parity is conserved; if it changes, parity is violated. This concept is fundamental in understanding the behavior of quantum systems and their interactions. The discussion emphasizes the simplicity of parity while highlighting its critical role in quantum mechanics.

I'm unsure about how parity is used or indeed what it actually is in quantum mechanics. If someone could shed some light on this it'd be a great help.

parity is something very simple.

If you have an object (or curve, equation..) in x, y, z, let x-> -x, y-> -y, z-> -z.
If the body (or equation or curve) looks exactly the same as before, then parity is conserved.
Otherwise, it is violated.R.
