Outline of Final Research Achievements

Charge localizations (dynamical localization: decrease of transfer integral t) driven by strong light field are investigated by hand-made 6 fs, 1.3 cycle, 100 MV/cm infrared pulses in charge ordered (CO) and dimer-Mott (DM) type organic conductors. Optical freezing of charge motions - decrease of plasma frequency (proportional to the square root of t) in (TMTTF)2AsF6 (CO), photoinduced metal to insulator transitions in alpha-(ET)2I3 (CO) and kappa-(ET)2X salts (DM) - are realized by >10 MV/cm electric field of 1.3 cycle infrared pulses.
