Strange warping geometry helps to push scientific boundaries
Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality. All matter can exhibit wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. The concept that matter behaves like a wave was proposed by Louis de Broglie (/dəˈbrɔɪ/) in 1924. It is also referred to as the de Broglie hypothesis.[1] Matter waves are referred to as de Broglie...
Wave–particle duality - Wikipedia
Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be partly described in terms not only of particles, but also of waves. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behaviour of quantum-scale objects. As Albert Einstein wrote:[1]
This is what Einstein ACTUALLY won the Nobel Prize for, NOT relativity....
Photoelectric effect - Wikipedia
The photoelectric effect is the emission of electrons or other free carriers when light hits a material. Electrons emitted in this manner can be called photoelectrons. This phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry and electrochemistry.During the years 1886-1902, Wilhelm Hallwachs and Philipp Lenard investigated the phenomenon of photoelectric emission in detail....
This topic was pretty much wholly abandoned after lasers...being as the paper here is in a microwave context, I think it'd quite likely be highly relevant to the problem as given here....
A maser (/ˈmeɪzər/, an acronym for microwave amplification by stimulated emission of radiation) is a device that produces coherent electromagnetic waves through amplification by stimulated emission. The first maser was built by Charles H. Townes, James P. Gordon, and H. J. Zeiger at Columbia University in 1953. Townes, Nikolay Basov and Alexander Prokhorov were awarded the 1964 Nobel Prize in Physics for theoretical work leading to the maser....

Scientists Just Made The World's First Diamond Maser That Operates at Room Temperature
For the first time, researchers have used diamond to build a solid-state maser that can operate continuously at room temperature. This could burst open the technology for everyday use such as medical imaging and security scanners at airports.
