Abstract
<p>Non-linear correlated charge motions driven by a 6-femtosecond nearly single-cycle strong electric field of >10 megavolts/cm are observed as a stimulated emission and an unconventional second harmonic generation (SHG) in a layered organic superconductor. These non-linear charge motions before an increase in the electron temperature are enhanced by critical fluctuations near the superconducting transition temperature. The stimulated emission is attributed to a synchronized petahertz charge oscillation. On the other hand, the unconventional SHG is induced by charge acceleration that is confirmed by carrier envelope phase dependence of the SHG. Quantum many-body analyses clarify the detailed mechanisms.</p>
