koppelingconstanten
Koppelingconstanten, often translated as coupling constants, are fundamental parameters in physics that quantify the strength of interactions between particles or fields. In quantum field theory, these constants determine how strongly fundamental forces, such as electromagnetism, the strong nuclear force, and the weak nuclear force, couple to matter particles.
For instance, in quantum electrodynamics (QED), the electromagnetic coupling constant, also known as the fine-structure constant
The value of a coupling constant is not always fixed; in some theories, they can vary with
In condensed matter physics, coupling constants also describe the strength of interactions within a material, such
