Abstract:

In this project, we investigated controlling the properties of materials by simply shining light ontothem. This is based on the fact that, if the energy of the incident light is below the absorption threshold, one will nothave direct absorption making it possible to observe coherent phenomenon. In this case, electrons and photonscan coherently hybridize forming so-called Floquet-Bloch states. Our goal is to use these Floquet-Bloch states toengineer materials with distinct properties. By tuning the properties of the incident light such as fluence, frequencyor polarization, one can change the resultant material properties.
