摘要
The authors observed the superluminal propagation at negative group velocity in C-60 toluene solution firstly. The theoretical analysis was made based on density matrix model of superluminal propagation. The simulation result was well consistent with experimental measurement. The largest time advancement of 3.58 ms was got at 5.6x10(-4) mol/l of sample concentration; the corresponding group velocity is -0.28 m/s. (c) 2007 American Institute of Physics.
