Sri Bhavya Muvva will present her comprehensive exam topic, “Attosecond Electron Pulses: Their generation and applications” in person.

Abstract: Recent progress in ultrafast electron diffraction and microscopy techniques has made it possible to image dynamics of atomic motion in femtosecond timescales. However, capturing electronic motions in matter or ultrafast processes requires electron pulses of attosecond pulse durations. Recent studies demonstrated the generation of attosecond electron pulses using different methods. In this talk, I will discuss a few methods used for the generation of the attosecond electron pulses, along with their current state-of-the-art capabilities and challenges in their implementation in diffraction and/ microscopy experiments. I will also discuss an experimental set-up that uses attosecond electron pulses for imaging attosecond dynamics of a proposed study.
