Hidden quantum mirrors trap light in 2D materials.

Do you know why rivers make the air cold? The reason for that is that the flowing river binds energy into it. The small waves that travel in the river in one direction pull air between them. And that’s the reason why a flowing river binds more energy than standing water. There is a possibility of making the layer. There is a wave movement that travels in one direction, making the layer invisible. In that case, the wave movement that travels in a certain direction moves energy fields with those waves. This is called harmonic movement. And theoretically, that thing can make it possible to create a system that has zero reflection in a certain direction. It's possible to aim the wave movement in one direction. 

“By miniaturizing THz spectroscopy to a chip-scale platform, James McIver’s lab has uncovered a promising new method for controlling quantum materials. Under certain conditions, two-dimensional (2D) materials can exhibit remarkable quantum states, including superconductivity and unusual types of magnetism. Scientists and engineers have long sought to understand why these phases appear and how they might be controlled.” (ScitechDaily, Physicists Find Hidden “Quantum Mirrors” That Trap Light in 2D Materials

That  can revolutionize things like electronics. And communication, as well as acoustics. The 2D material can control electromagnetic and acoustic waves. There is a possibility of using an arrowhead-shaped triangular graphene structure to make the phonons. When an energy impulse hits the bottom of the graphene triangle, it pushes electrons in a certain direction. That makes it possible to control acoustic waves. And that can be a new tool. To control objects in nanotechnology. 

2D materials are materials whose thickness is one atomic layer. Those materials. For example, graphene has incredible abilities. In graphene, energy impulses spread across the material without forming a minimum backward reflection. And that means there are no standing waves between the graphene layer’s carbon atoms. Or the backcoming energy wave can push those waves forward. If there is some kind of standing wave, that energy travels past those atoms. Graphene is homogeneous. Carbon atom layer. 

There is a possibility. To aim energy in graphene by putting low-energy points or energy potholes into the layer. If the edge of graphene is on a lower energy level, that aims energy to the edge and away from the graphene. That makes graphene hard, but it also allows researchers to create new systems that can control energy flows over graphene. Making energy hills and potholes is possible. To aim energy flows that follow certain routes on that layer. Those energy hills. That which has a certain form can also channel energy into the graphene material. 

When we think of the ability to control 2D materials. We must just inject energy into them. Researchers have found that 2D materials. These are stressed with terahertz radiation from structures called cavities. Those cavities are waves that form on the material. When energy travels to a material. It stays in it. And in that process, the reflection is impossible. We see material only if it reflects radiation. And if we create a material that absorbs all energy that impacts it, we can create a material. That looks like a shadow. The fact is that sooner or later, material sends an energy impulse. There is a possibility of creating a lower energy inner. But a separated layer. Where energy can travel. When energy travels away from the observer, the observer cannot see the layer. And that is one of the things that we must realize. The ability to control energy flow in materials opens incredible possibilities. In stealth and high-speed flying. 

The biggest problem with 2D materials is that they must be kept in 2D form. The 2D materials lose their abilities if there is more than one material layer. There is a possibility to pile 2D atom layers on top of each other. Then, nano-pillars can keep those layers separate. It’s possible to send some kind of wave movement between those layers. And in that case-. Those energy waves can act as a thermal pump. That transfers energy in a certain direction. The system can be based on the laser beam. That travel in the fullerene tubes. When the energy field falls between those laser impulses. Those laser impulses take energy with them. The system can also use electrons or some other particles to act as a thermal pump. that transports energy into the desired direction.
