Attractive and repulsive terms in multi-filament dispersion interactions
Subhojit Pal, John F. Dobson, Mathias Boström
Filamentary objects such as nano-wires, nanotubes and DNA are of current interest in physics, nanoscience, chemistry, biology and medicine. They can interact via strong, exceptiona…
Beyond Attraction: A Novel Approach to Repulsive Casimir-Lifshitz Forces using heterogeneous off-stoichiometry in gapped metals
S. Pal, S. Osella, O. I. Malyi +1
We uncover a novel physical mechanism that enables a switch between attractive and repulsive Casimir forces when a Teflon surface interacts with a new form of quantum material (i.e…
Inverse design for Casimir-Lifshitz force near heterogeneous gapped metal surface
M. Boström, S. Pal, H. R. Gopidi +4
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 surfa…
"Observations on the possible electromagnetic nature of nucleon interactions and pions" -- historical manuscript from 1969 by B. W. Ninham and C. Pask
Mathias Boström, Drew F. Parsons
This manuscript presents an historical perspective prepared by Barry Ninham and Colin Pask in 1969 on the connection between quantum electrodynamics theory and nucleon interactions…
Prediction of a measurable sign change in the Casimir force using a magnetic fluid
Long Ma, Larissa Inácio, Dai-Nam Le +2
We demonstrate quantum levitation controlled by Casimir forces acting between a polystyrene surface and a Teflon-coated metallic substrate immersed in a mixture of Toluene and magn…
Nanorod Pair Complexes Manipulated via Magnetic Casimir Forces
S Pal, L. M. Woods, C. Persson +3
Controlling nanoscale interactions to suppress aggregation from short-range attractive forces is a key problem in nanoengineering. Here, we demonstrate a route to modulate Casmir-L…
