Laser mastery narrows down sources of superconductivity

Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2-D materials, scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.
