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 2D materials, collaborating scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.
