The optical tweezer of skyrmions [PDF]
npj Computational Materials, 2020 AbstractIn a spin-driven multiferroic system, the magnetoelectric coupling has the form of effective dynamical Dzyaloshinskii–Moriya (DM) interaction. Experimentally, it is confirmed, for instance, for Cu2OSeO3, that the DM interaction has an essential role in the formation of skyrmions, which are topologically protected magnetic structures.

Thermophoretic tweezers for single nanoparticle manipulation
Beilstein Journal of Nanotechnology, 2020 We present the trapping and manipulation of a single nano-object in an aqueous medium by optically induced temporally varying temperature gradients. By real-time object tracking and control of the position of the heating laser focus, we can precisely ...

Interferometric Optical Tweezers [PDF]
Optics and Photonics News, 1996 Abstract We report the first experimental demonstration of an optical trap that uses interference fringes for the trapping and micro-manipulation of microscopic objects. The finges can be generated either by two-beam interference or by projecting a reduced image of a Ronchi ruling on the sample plane.
