Enhancing Optical Gradient Forces with Metamaterials
Physical Review Letters, 2013 We demonstrate how the optical gradient force between two waveguides can be enhanced using transformation optics. A thin layer of double-negative or single-negative metamaterial can shrink the interwaveguide distance perceived by light, resulting in a more than tenfold enhancement of the optical force.

Probing the Casimir force with optical tweezers [PDF]
EPL (Europhysics Letters), 2015 We propose to use optical tweezers to probe the Casimir interaction between microspheres inside a liquid medium for geometric aspect ratios far beyond the validity of the widely employed proximity force approximation. This setup has the potential for revealing unprecedented features associated to the non-trivial role of the spherical curvatures.

The zoo of nonconservative optical forces
Journal of Physics: Conference Series, 2018 Optical forces are usually described as conservative ones originating from intensity gradients in optical tweezers. However, the fundamental optical action on matter is nonconservative. In contrast to gradient forces, the spectrum of action of nonconservative forces is much wider: they can propel, pull, rotate objects or move objects along complicated ...

Optical Forces in Metal/Dielectric/Metal Fishnet Metamaterials in the Visible Wavelength Regime
IEEE Photonics Journal, 2012 The optical force is calculated on a nanoparticle in close proximity to the surface of a fishnet metamaterial based on a metal/dielectric/metal film when illuminated at visible wavelengths.
