Photon-neutrino interactions open new views to those mysterious particles.
In some visions, the neutrino is very close to hypothetical WIMP (Weakly interacting massive particle) which are dark matter particles. There could be two ways how WIMP can be massive. One is that a single WIMP can have a higher energy level than visible material. And the second is that there are lots of WIMPs that are massive in entirety.
So the WIMP makes interaction between visible material as a group. In some models, there are two types of WIMPs. The high-energy WIMPs form the hot dark matter. And low-energy WIMPs could be particles of the cold dark matter. And in visible material. The energy level is between those hot and cold WIMPs or hot and cold dark matter.
Normally, think that the universe has three main parts. Those parts are dark energy, dark matter, and visible material. In some models, there is hot and cold dark matter. And visible material is between those dark matter types. The thing, that determines material visibility is the direction of energy flow. If energy travels from higher energy material into lower energy material.
And there is no echo from that material. The interaction is one-way. That means there is no energy flow back to higher energy particles, and that makes lower energy particles invisible. In that model, energy flows from visible matter into cold dark matter. And that makes cold dark matter invisible to us.
There is the possibility that there is also the fourth type of material, which we can call grey material. That grey material is something between dark and visible material.

We can think that "dark matter" is so-called hot dark matter. Which energy level is higher than the visible material's energy level?
When hot dark matter loses its energy it turns into visible material, and when visible material loses its energy. It turns into cold dark matter. In that model, dark energy is the last view of material before it falls into 2D form.
In that model, the neutrino could represent very old material that lost its energy. Because neutrino's energy level is very low it's hard to detect. And it loses its energy into the cold dark matter. This model is conducted from the model of the universe's ultimate fate. The fate of material is turned into wave movement. And maybe neutrino is the particle that is transforming from the visible material into dark matter.
Neutrinos are one of the most interesting. And at the same time very mysterious particles. Those particles have mass, but they do not have strong interactions. That makes neutrinos able to travel through planets. And kilometers-thick lead doesn't stop those particles. There is a possibility that neutrinos can travel through neutron stars, and if that thing is true, they can help us to understand the dense objects in the universe.
But in that case, researchers must confirm that those neutrinos traveled through the neutron stars. The photon-neutrino impacts open new views to those mysterious particles. If we think about the shape of the neutrino, they could be very interesting tools in quantum technology. Neutrinos could transport information over long distances.
So quantum computers could use neutrinos in long-distance quantum communication. The problem is that those neutrinos are hard to capture and manipulate. And that thing makes it hard to benefit them. But if researchers could someday capture neutrinos in photon traps, they can have the tool that can used in high-class quantum systems that can observe interactions inside atoms.
