Inverse design for Casimir-Lifshitz force near heterogeneous gapped metal surface
arXiv:2402.09031 · doi:10.1103/PhysRevB.110.045424
Abstract
The Casimir-Lifshitz force is calculated between a heterogeneous gapped metal surface and a silica sphere attached to an AFM cantilever tip. We demonstrate that heterogeneous surface patches with different off-stoichiometry surface properties lead to changes in the predicted distances for a specific force. This can incorrectly be interpreted as occurrences of surface roughness.
