It seems there might be a slight misunderstanding or confusion in your question. There is no widely known or established "quantum theory of spontaneous movement" that I am aware of. Quantum mechanics provides a framework for understanding the behavior of particles and systems at the microscopic level, but it does not specifically address spontaneous movement as a distinct phenomenon.
However, in the context of quantum mechanics, there are phenomena related to particle motion and behavior that might be relevant to what you're asking. For example:
Quantum fluctuations: Quantum mechanics allows for the existence of fluctuations in the properties of particles, even in the absence of external influences. These fluctuations can affect the position, momentum, and energy of particles, leading to a level of inherent randomness or "spontaneity" in their behavior. This is often referred to as quantum uncertainty or indeterminacy.
Quantum tunneling: Quantum tunneling is a phenomenon where a particle can pass through a barrier that, according to classical physics, it should not be able to overcome. This occurs due to the wave-like nature of particles and their associated probabilities. Quantum tunneling has been experimentally observed in various systems and has practical applications in devices such as tunneling electron microscopes and semiconductor devices.
Brownian motion: Brownian motion is the random motion of microscopic particles suspended in a fluid due to the collisions with surrounding molecules. While the classical theory of Brownian motion describes this as a statistical process, quantum mechanics underlies the behavior of the individual particles involved.
It is important to note that these phenomena are not necessarily considered "spontaneous movement" in the sense of a macroscopic object exhibiting self-initiated motion without external influence. Rather, they describe the inherent probabilistic and random nature of particles and their behavior at the quantum level.
In any case, it is always crucial in science to formulate hypotheses based on existing theories, perform experiments, and gather empirical evidence to support or refute those hypotheses. If there is a specific theory or concept you are referring to regarding "quantum theory of spontaneous movement," please provide more details so I can address it more accurately.
