A team of researchers from Boston College has created a new metal sample in which movement
“Usually electrons are scattered by phonons, whichleads to the usual diffuse motion of electrons in metals. Our experiment showed that when electrons interact strongly with phonons, they form a single electron-phonon liquid. The new liquid will flow inside the metal in the same way as water flows in a pipe, ”the scientists noted. This discovery will spur further exploration of the material and its potential applications.

Using a special technique, “quantumvibrations ", to estimate the mass of electrons in the material, the researchers found that the mass of electrons in all trajectories was three times the expected value. Scientists point out that this is an unexpected result for such a material.
"It was really surprising becausewe did not expect such «heavy electrons» in seemingly simple metal,” the scientists noted. “We realized that the strong electron-phonon interaction is responsible for the behavior of heavy electrons. As electrons interact with lattice vibrations, or phonons, they are pulled behind the lattice and appear to have gained mass and become heavy.”
The next step of scientists will be to search for similarproperties of materials - for this they will use the electron-phonon interaction. The team will also focus on controlling the hydrodynamic fluid of electrons in such materials and developing new electronic devices.
