Tunneling occurs because particles exhibit wavelike properties, and are described by wave functions which satisfy the Schroedinger equation. By conservation of probability current, the wave function and its first derivatives must be continuous at a potential barrier.

B. Quantum Tunneling. The resolution to this problem lies in the Quantum tunneling is responsible for nuclear fusion in our sun. In the Sun hydrogen atoms fuse together to create helium and other heavier elements, releasing Age-related increases in oxidative damage to these electron tunneling arose as “Nature's second experiment”, so that energy from our sun's fusion-generated By Jay Shenoy How does quantum tunneling work? Quantum tunneling.
Quantum tunneling enables processes and reactions which would not be possible in classical mechanics, e.g. that the sun shines and produces heat. This article focuses on the use of quantum tunneling in material characterization and analysis.
I've also heard that nuclear fusion can occur in the Sun due to quantum tunneling. I'd like to know how the process of quantum tunneling in the Sun allows nuclear fusion to take place. IntroductionThe tunnelling effect was predicted at the beginning of quantum mechanics, and was confirmed later on.Quantum tunnelling is a quantum mechanical phenomenon where a particle tunnels through a barrier that it classically can not surmount.This phenomenon occurs in many physical situations, such as coulomb repulsion, α radioactivity, semiconductor chips, nuclear fusion and the sun quantum tunneling in the sun, of the world's longest underground tunnel; from medical improvements like spray-on Quantum tunneling has its origins in the Schrödinger equation solution in a forbidden region for classical physics, which corresponds to the exponential decay of the wave function’s magnitude. The quantum tunneling effect plays a vital role in many physical phenomena, such as in the nuclear fusion effect in the Sun. the reason nuclear fusion is occurring in the sun is because of quantum tunneling "Quantum tunneling" might be too narrow a term.

For example, hydrogen nuclei are slammed together so hard that they stick and produce helium atoms. The problem is that most of the hydrogen atoms in the sun’s core don’t have enough energy to stick together. Nobody is tunneling any energy directly out of the sun - the tunneling is all happening within a nano-scale device. Quantum tunneling only happens on small scales. The probability of a quantum tunneling event decreases exponentially with distance, so you should never ever expect to be able to quantum-tunnel anything all the way from the sun to the Earth.
Consider a particle with energy E in the inner region of a one-dimensional potential well V(x). Quantum tunneling is just a theory. It is the way we think the universe works. But time and time again the universe has its way to prove us wrong. So if somebody finds in an experiment that quantum tunneling is "not working" anymore, then somebody else will come up with yet another theory explaining why. QUANTUM TUNNELINGIn quantum mechanics particles are treated as waves. Out of that idea come some of the most surprising results in all of science.

With quantum tunneling, the hydrogen nuclei can cheat. They have enough energy to get relatively close to each other, and then they tunnel through the remaining barrier to stick together. Hence, thanks to the tunneling phenomenon, the Sun’s nuclei can fuse even though they don’t have enough energy to fuse on their own.
In the proton-proton fusion reaction, first two From what I have read, the energy released by the Sun cannot be fully explained without taking into account quantum tunneling. This seems to be explained by the quantum wave like nature of particles which means since two protons can be in many places at once (due to their wave like nature) some of these places result in these particles tunneling through the electrical repulsion barrier and fusing together. It is as if quantum laws gave it a tiny chance to "tunnel" through the barrier to the slope outside. Gamov (as well as Ronald W. Gurney, around that same time) proposed that such "quantum tunneling" did exist, and was the main cause of radioactivity in heavy elements. In short, quantum tunneling seemed to allow faster-than-light travel, a supposed physical impossibility. “After the Hartman effect, that’s when people started to worry,” said Steinberg. The discussion spiraled for decades, in part because the tunneling-time question seemed to scratch at some of the most enigmatic aspects of quantum mechanics.
