I don't understand why you need quantum effects to explain the tribo electric effect. ( Unless the cat you are rubbing belongs to Shroedinger :wink:)

https://en.m.wikipedia.org/wiki/Triboelectric_effect said:
Although the part 'tribo-' comes from the Greek for "rubbing", τρίβω (τριβή: friction), the two materials only need to come into contact for electrons to be exchanged. After coming into contact, a chemical bond is formed between parts of the two surfaces, called adhesion, and charges move from one material to the other to equalize their electrochemical potential. This is what creates the net charge imbalance between the objects. When separated, some of the bonded atoms have a tendency to keep extra electrons, and some a tendency to give them away, though the imbalance will be partially destroyed by tunneling or electrical breakdown (usually corona discharge). In addition, some materials may exchange ions of differing mobility, or exchange charged fragments of larger molecules.

The triboelectric effect is related to friction only because they both involve adhesion. However, the effect is greatly enhanced by rubbing the materials together, as they touch and separate many times.[4] For surfaces with differing geometry, rubbing may also lead to heating of protrusions, causing pyroelectriccharge separation which may add to the existing contact electrification, or which may oppose the existing polarity. Surface nano-effects are not well understood, and the atomic force microscope has enabled rapid progress in this field of physics.

I just wanted to learn in quantum field theory, electrons also move from one object to another object, for example, when there is an electrical discharge when I touch another person or the door handle?

No. The things you mention are not quantum physics. Quantum field theory is a very advanced subject. It takes years of study to get to QFT.

What is your educational background?

Did you understand that stuff I posted from Wikipedia?

Are you looking for ways to learn more physics?

I apologize for the stupid question. I recently heard about Quantum Field Theory.
I do not need any math, I just want to know how these processes are happening.

You might want to answer these questions.
I have a school education.
I understood the information from Wikipedia.
I want to clarify how this works in Quantum Field Theory.
Is it also the transfer of electrons?
Thank you

Your question can't be answered on an Internet forum. The answer would be longer than a thick book.

For an introduction to QFT, try this video.

thanks for the video, very interesting. Once again I apologize. I just want to understand in quantum field theory that electrons are also transferred from one object to another, as in the classical theory? Thank you

Sorry, the answer is no. But a full explanation would be too long.
