Abstract :

With the tremendous technological advancement in recent years, it becomes possible to generate ultra-short and ultra-intense laser pulses. It is natural to envision imaging the electronic motion during physical processes using these pulses. In this talk, I will discuss how the technologies, originally developed for gaseous medium, have been extended to solids. Two examples will be discussed: how the presence of different kinds of defects in solid affects the generation of high harmonics and how these localized defects can be imaged using high-harmonic generation. The other one will be performing valleytronics in graphene, which is not considered feasible till date.
