Abstract:
Modern light generation technology has now evolved to the point where a theorist may risk asking an experimentalist to generate light pulses where individual oscillations of the electric field are shaped almost at will, without fear of being immediately kicked out of the room. Control of the carrier-envelope phase of few-cycle pulses is now almost routine. One can also generate complex polarization states in two and three dimensions, sculpting the Lissajous figures drawn by the electric field vector during a single optical cycle. As these fields can be made strong enough to compete with the internal electric fields in a medium, coherent electronic motion can be excited and shaped almost at will, at the time-scale of a single light oscillation.
How can we use such opportunities? What happens to a crystal exposed to such light? How do we change its effective band structure and density of states? Can these changes be controlled?
To address these question, I will consider several examples where our ability to control light on the PHz time-scale leads to interesting results, starting with nearly PHz control over selective excitations and de-excitations of the desired valleys in a Brillouin zone, and going all the way to light-induced topology in solids and multi-dimensional spectroscopy of highly nonlinear optical response in strongly correlated solids.
