The Instituto de Ciencia de Materiales de Madrid (ICMM) is an institute of the Consejo Superior de Investigaciones Cientificas (CSIC) (Spanish National Research Council) founded in December 1986, that belongs to the Area of Science and Technology of Materials, one of the eight Areas in which the CSIC divides its research activities.


Our mission is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge.

Momentum-Topology-Induced Optical Pulling Force

We report an ingenious mechanism to obtain robust optical pulling force by a single plane wave via engineering the topology of light momentum in the background. The underlying physics is found to be the topological transition of the light momentum from a usual convex shape to a starlike concave shape in the carefully designed background, such as a photonic crystal structure. The principle and results reported here shed insightful concepts concerning optical pulling, and pave the way for a new class of advanced optical manipulation technique, with potential applications of drug delivery and cell sorting.

(a) Changes of max[Fx(x, 0)] exerted on different elliptical objects (see the inset). The refractive index varies from 1.4 to 2.6, and the semiaxis rx changes from 0.1 to 1 μm, (ry = 0.1 μm is fixed for convenience). In the colored region, the objects experience continuous pulling forces when they shift along x axis. P1 and P2 are two representative objects analyzed in detail in (b) and (c). (b) Scattered field by the object P1. Because of the symmetry of the structure, only the half space of y > 0 is shown. Forward scattering occurs which generates a continuous pulling force. (c) Scattered field by the object P2. Backward scattering results in a pushing force and cancels the pulling force generated by the forward scattering.
