Contribution

It provides a critical perspective by connecting recent experimental results with existing theoretical research on Casimir interactions.

Findings

Experimental observations of transverse forces in misaligned plates

Prior theoretical studies on liquid-separated Casimir effects

Emphasis on the theoretical background relevant to recent experiments

Abstract

K\"u\c{c}\"uk\"oz et al., Sci. Adv. 10, eadn1825 (2024) reported an experiment, which shows that conducting plates in the misaligned system separated by a liquid may experience transverse interactions at small separations. We point out that the effects might have been examined in detail in theoretical studies, New J. Phys. 24, 113036 (2022) and Phys. Lett. A 495, 129304 (2024).
