Abstract

Recent developments of table top laser sources have changed the way we study and control material properties, previously achieved through chemical substitutions or with static perturbations such as pressure, electric and magnetic fields. In this talk I will present few examples of how the emerging tool of time and angle resolved photoemission spectroscopy is changing the way we study the properties of a variety of 2D materials and how this tool will allow measurements of devices under working conditions; access to hidden states of matter, as well as design of new photo functional materials. The case of unconventional superconductors and graphene will be discussed in details illustrating the power of this unique time-resolved spectroscopy.
