Controlling Coherence Using the Internal Structure of Hard Pi Pulses
(Monday, 25 August, 10:30-11:15)

Abstract:

Pulses are a fundamental tool used broadly throughout magnetic resonance (NMR, MRI, ESR), in atomic physics, and more recently in quantum information processing. In this talk, we show how the tiny difference between hard Pi pulses and their delta-function approximation can be exploited as a new resource to control coherence, enabling novel classes of spin echoes with promising applications in NMR, MRI of solids, and beyond.
