Finite bandwidth and surface roughness reduce measured Casimir forces compared to idealized models
Is it true that finite bandwidth and surface roughness reduce measured Casimir forces compared to idealized models?
Yes. Finite bandwidth (material conductivity properties) and surface roughness significantly decrease measured Casimir forces compared to idealized parallel plate models.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The claim addresses specific physical factors (finite bandwidth/conductivity and surface roughness) that alter the Casimir force relative to ideal models. Papers [0] and [2] explicitly confirm that real-world surface roughness and material properties (such as finite conductivity/bandwidth) reduce or suppress the Casimir force compared to idealized calculations. The remaining papers are tangential and do not discuss Casimir force corrections.
