Spectroscopic measurement of the Casimir-Polder force in the intermediate regime
K. Ton, G. Kestler, D. A. Steck +1
The Casimir-Polder (CP) effect -- the force between a neutral atom and an uncharged conducting plate in empty space -- is an intriguing consequence of quantum vacuum fluctuations.…

Pathwise Differentiation of Worldline Path Integrals
Jonathan B. Mackrory, He Zheng, Daniel A. Steck
The worldline method is a powerful numerical path-integral framework for computing Casimir and Casimir-Polder energies. An important challenge arises when one desires derivatives o…
