Klein tunneling has been noticed for the first time.

Klein tunneling means that the particle can pass the energy loss while the particle travels through the wall doesn't depend on the weight or width. The subatomic particles can pass the wall in the form of wave movement or they can jump between atoms but that is the normal tunneling.

In Klein tunneling also atoms can pass the barrier without losing their mass or energy. The Klein tunneling has been made by using the artificial photonic crystals by using the sound waves in the University of Hong Kong(2).

How to benefit Klein tunneling?

The Klein tunneling can be the key to extremely powerful loudspeakers. When the soundwave is traveling in the medium, there could be possible to impact more energy than it releases. One of the most interesting things is what if Klein tunneling could do by using solid materials like concrete and make it happen by using ions or electrons. That thing makes it possible to use the Klein tunneling also in the new type of communication.

The thing that makes Klein tunneling interesting is that it can make it possible to make the new type of data transmission possible where the data travels in the form of ions through walls. So how we would make Klein tunneling without special photonic crystals? The answer could be that the wall can just stress with electricity or some other type of energy.

When energy is pumping into the barrier it would transfer to the particles that are traveling in the barrier. That means that the energy can replace the energy that is transferring to the barrier but if the energy level crosses the energy loss, that causes that the particle would get a higher energy load. So by using this kind of system is possible to make as an example extremely loud sound by pumping energy to the soundwaves that are traveling in the medium.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low. The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away. When the box is filled with quantum gas and som

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies.

An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material.
