Direct evidence of light-induced phase-fluctuations in cuprates via time-resolved ARPES Open
Phase fluctuations are widely accepted to play a primary role in the quench of the long-range superconducting order in cuprates. However, an experimental probe capable of unambiguously assessing their impact on the superconducting order pa…
