Optical manipulations utilizing the mechanical effect of light have been indispensable in
various disciplines. Among those various manipulations, optical pulling has emerged …

Usually, an unfocused light beam, such as a paraxial Gaussian beam, can exert a force on
an object along the direction of light propagation, which is known as light pressure …

Optical tractor beams capable of pulling particles backward have garnered significant and
increasing interest. Traditional optical tractor beams are limited to free space beams with …

We propose a robust scheme to achieve optical pulling force using the guiding modes
supported in a hollow core double-mode photonic crystal waveguide instead of the …

Optical pulling provides a new degree of freedom in optical manipulation. It is generally
believed that long-range optical pulling forces cannot be generated by the gradient of the …

We propose a double-layer graphene sheets side coupling to a strip of graphene to obtain
the optical pulling or pushing force. Combined with coupled mode theory and finite …

For flexible tailoring of optical forces, as well as for extraordinary optomechanical effects,
additional degrees of freedom should be introduced into a system. Here, we demonstrate …

The behavior of Fano resonance and the reversal of near field optical binding force of
dimers over different substrates have not been studied so far. Notably, for particle clustering …

In the framework of the electric dipole approximation, this work demonstrates the generation
of a pulling/attractive longitudinal force and an axial spin torque sign reversal causing …
