Title: Sub-femtosecond electron pulses and sub-femtosecond measurements with conventional laser pulses
Since the inception of the laser it has been assumed that, to make faster measurements, shorter pulses were needed. In this talk I will show that this is not generally true. I will describe how conventional laser pulses can be used to resolve electronic and nuclear motions in a molecule with sub-femtosecond and sub-Angstrom precision. The secret lies in (i) creating and utilizing correlation between the electronic and nuclear motions and (ii) using the laser field to control one of these motions. I will describe both theory and experiments that demonstrate the concept.
