Brilliant source of 19.2 attosecond soft X-ray pulses below the atomic unit of time
Fernando Ardana-Lamas, Seth L. Cousin, Juliette Lignieres +1
Electronic correlations occur on attosecond timescales, dictating how chemical bonds form, energy flows, and materials respond to light. Capturing such many-body processes requires…
