Comment on Influence of non-conservative optical forces on the dynamics of optically trapped colloidal spheres: The fountain of probability, arXiv:0804.0730v1

TL;DR

This paper critiques a previous study by arguing that the data provided do not conclusively demonstrate the existence of circulation in a static optical trap of colloidal spheres.

Contribution

It provides a critical analysis challenging the interpretation of circulation in optical trapping experiments, emphasizing the need for more conclusive evidence.

Findings

The data are insufficient to confirm circulation in static optical traps.

The critique questions the interpretation of non-conservative optical forces.

Highlights the importance of rigorous data analysis in optical trapping studies.

Abstract

We demonstrate that the data presented in the manuscript by Y. Roichman et al. are not sufficient to show that the circulation of a trapped particle exists in a static optical trap.
