Feedback Cooling and Thermometry of a Single Trapped Ion Using a Knife Edge
Hans Dang, Sebastian Luff, Martin Fischer +2
We report on a simple and easy to implement method of feedback cooling trapped ions to temperatures below those achievable using only Doppler cooling. Additionally, the feedback co…
Benchmarking quantum phase-space methods for near-resonant light propagation
Mojdeh S. Najafabadi, Joel F. Corney, Luis Sanchez Soto +1
We study the dynamics of light interacting with a near-resonant atomic medium using the truncated Wigner and positive P phase-space representations. The atomic degrees of freedom a…
Experimental Demonstration of Commutation Relations Using Intensity Correlations
Hans Dang, Sebastian Luff, Martin Fischer +4
The canonical commutation relation is a cornerstone of quantum theory and underlies the Heisenberg uncertainty principle. Although uncertainty relations have been extensively teste…
Wave Phenomena and Wave Equations
Gerd Leuchs, Mojdeh S. Najafabadi
For any kind of wave phenomenon one can find ways to derive the respective dispersion relation from experimental observations and measurements. This dispersion relation determines…
