Quantum Breakthrough Reveals Superconductor’s Hidden Nature.
Thermoelectric effect reveals full picture of fluctuations in superconductivity. Weak fluctuations in superconductivity,[1] a precursor phenomenon to superconductivity, have been successfully detected by a research group at Tokyo Institute of Technology (Tokyo Tech). This breakthrough was achieved
A research team led by Assistant Professor Koichiro Ienaga and Professor Satoshi Okuma of the Department of Physics, School of Science at Tokyo Tech reported in Physical Review Letters in 2020 that quantum motion of magnetic flux lines occurs in an anomalous metallic state by using the thermoelectric effect, in which voltage is generated with respect to heat flow (temperature gradient) rather than current. This result reveals that the anomalous metallic state in a magnetic field at absolute zero in two-dimensional superconductors, which has remained unresolved for 30 years, originates from the existence of the quantum critical point.
