Electron repulsion in QFT (Quantum Field Theory) refers to the phenomenon where two electrons, due to their negative charges, experience a force of repulsion when they come into close proximity with each other.
In QFT, electron repulsion is explained through the exchange of virtual photons between the two electrons. These virtual photons carry the electromagnetic force, causing the electrons to repel each other.
Electron repulsion plays a crucial role in determining the behavior and interactions of electrons in atoms and molecules. It is responsible for the stability of matter and the formation of chemical bonds between atoms.
In QFT, electron repulsion cannot be completely cancelled out, but it can be counteracted by the attractive forces between the electrons and the positively charged protons in an atom. This results in the formation of stable atoms and molecules.
In quantum mechanics, the concept of electron repulsion is closely related to the phenomenon of quantum entanglement, where the properties of two or more particles become correlated and cannot be described independently. In the case of electron repulsion, the spin and charge of the electrons become entangled, affecting their behavior and interactions.
