Ultrafast Strong Field Phenomena in 2D materials: attosecond interferometry and lightwave induced current

Hamed Koochaki Kelardeh
Graphene interacting with a few-femtosecond intense optical pulse exhibits unique and rich electronic properties dramatically different from electron dynamics in insulators and metals. Here, we propose an attosecond strong optical field interferometry in 2D Dirac materials which reveals their chirality without employing a magnetic field. A circularly polarized optical pulse with strong amplitude and femtosecond time scale causes electron to circle in the reciprocal space accumulating the dynamic phase along this closed trajectory as well...
