Strange metals in the intermediate zone between dielectrics and conductors have free electrons that can carry an electric charge. but they do not meet full conductivity criteria.
The synthesis of quantum and classical physics has enabled the understanding of these materials. But recent discoveries have changed our understanding of electric current, the cornerstone of modern physics. It could be wrong.
The dominant theory of electric current is based on charge transfer by quasiparticles, which are a manifestation of the collective action of electrons. Discreteness of electric current usually manifests itself not in a consistent and smooth charge transfer, but in the form of shot noise characterized by bursts.
Scientists trying to solve the mystery of how current flows in strange metals have produced nanoconductors from this compound. ytterbium, rhodium and silicon (YbRh2Si2).
These nanoconductors, measuring 200 nm x 600 nm, belong to the category. strange metals and exhibit atypical properties close to absolute zero.
Purpose of the experiment. During the research, scientists carefully monitored the movement of electrons, assuming that they followed the expected behavior of different groups that behave like quasiparticles. But the unexpected result showed that the electric current flows smoothly, without the expected partial noise fluctuations, like water in a wide trough.
In essence, challenging conventional wisdom, the charge was found to be partially transferred as if the electrons were not present.
This raises the possibility that the charge carrier in metals could be something other than electrons, involving as yet undiscovered quantum effects.
Understanding this phenomenon could potentially unlock the secret to achieving superconductivity at normal temperatures. Resistance behavior in strange metals differs significantly from conventional metals near absolute zero; It increases gradually and linearly rather than a sudden jump from zero to high resistance.
If scientists can extend this behavior to higher temperatures, it could have significant impacts on energy. More effective and practical application of superconductivity. But the path to such discoveries remains hidden in the special and mysterious nature of strange metals.
