The past decade has seen the rapid technological developments of attosecond (10^-18 s) light sources. These pulses have the timescale of the electron motion in atomic and molecular systems, and are able to probe or control many-electron interaction with the temporal resolution of attoseconds. We theoretically demonstrate that by dressing atoms with intense few-femtosecond lasers, the many-electron dynamics can be controlled, and the change can be probed by attosecond light pulses. This technique further enables the control of light, which is similar to electromagnetically induced transparency effect, in the attosecond time domain and in the XUV to soft X-ray energy region.
