Temporal Shaping of Free-Electron Wavefunctions: Probe of Quantum Coherence and Source of Quantum Light

CANCELLED!

(Because unexpected personal reasons!)

Abstract

The temporal modulation of free electrons can alter their quantum interaction with optical
fields and with excitations in materials. We present how this temporal shaping can be
utilized to probe and induce quantum coherence in materials and to create non-gaussian
states of light.
The coherent interaction between free electrons and optical nearfields scattered from
illuminated nanostructures provides an efficient way to modulate the temporal
distribution of free electrons. In this seminar, I will discuss how this new degree of
freedom allows us to perform tasks such as quantum measurements and coherent
control. Additionally, we show how the temporal modulation changes the radiation
pattern of the free electron, achieving optical cat states and GKP states with high
fidelity
