How to twist, turn and kick ions using structured light
- Speaker: Christian Schmiegelow
- Event Type: Seminar
- Date and Time: 06/25/2025 3:00 pm - 06/25/2025 4:00 pm
- Location: Willamette 110
Abstract: I will present four experiments which show striking properties of structured beams when interacting with a single well-localized atom. I will first show what happens when you place a single atom at the dark center of a vortex/doughnut beam. Surp… Read More
