There is movement in the place where nothing should move.

The zero kelvin or absolute zero is ( -273, 15 C). Liquid Helium freezes at that temperature.

At that temperature, all movement ends. That is also the energy minimum in the universe. Researchers reached absolute zero in the laboratory. 

The real universe is 3 degrees warmer. The cosmic background called 3K radiation rises its temperature. But there is the possibility that in these ultra-cold conditions is the movement. Ultra-cold quasiparticles called phases can keep moving even if everything else freezes. The phason forms energy flow on the lattice temperature is adore zero. The phason is like an energy droplet that flows on the layer. The reason why phason exists is in the Pauli exclusion principle. 

There are no two identical fermions in the system. So all particles in the system are a little bit different. And that causes energy flows in the system. Those energy flows can form things like small quasiparticles in the system. Normally those quasiparticles don't matter very much. But in absolute zero those particles have meaning. 

"A moiré pattern formed by two units of parallel lines, one unit rotated 5° clockwise relative to the other". (Wikipedia, Moiré pattern). Same way particles and their energy fields behave. That means there is always certain inaccuracy in all systems. That inaccuracy means that. No system can keep its energy forever. No object can move 100% of its energy to another. When energy travels from other particle to another it pushes the receiving particle. Even in the lowest energy levels, there is energy movement between particles. Energy travels between electrons and the atom's nucleus. Same way gluons between quarks transport energy inside the atom's core. 

The image above shows the Moiré potential. There are always energy peaks, and energy valleys even in the lowest energy materials. Those potential differences form when electrons orbit around the atom's core. And that means that all surfaces seem waving if we can see them using strong enough microscopes. 

Those things are important in the quantum technology. The ability to control those waves brings new tools for quantum technology. If those waves travel in one direction that allows them to move qubits like a ball that rides on those waves. 

The reason for that is that quarks and electrons that form material travel different distances through different quantum fields. So all those subatomic particles have a little bit different energy levels. And energy always travels to a lower energy point. Even if researchers try to remove energy from the system they are doomed to fail. 

One of the reasons for that is material is one energy form. When the shape of the universe changes that forms space between those particles. So the particle's energy field tries to fill that hole. Same way when electrons and other particles spin, that makes energy flow to the system. 

There is always movement in the material. Electrons orbit the atom's nucleus and that means they harness energy from the atom's core. At that temperature, the electron can impact another electron and from the energy flow between them. In the same way things like the universe's expansion cause material vaporization. And that causes energy flows even in absolute zero.
