"Discovery of Exotic Charge Transport in Quantum Material Shocks Physicists"
Physicists at Rice University have conducted quantum noise experiments on a "strange metal" quantum material, providing evidence that electricity flows through these materials in an unusual liquid-like form that cannot be explained by quasiparticles. The experiments measured quantum charge fluctuations known as "shot noise" and found that the noise was greatly suppressed compared to ordinary wires. The researchers suggest that this may indicate that quasiparticles are not well-defined or that charge moves in more complex ways. The study's findings contribute to a better understanding of charge transport in quantum materials and raise questions about the nature of strange metals in various physical systems.
