Tailoring bistability in optical tweezers with vortex beams and spherical aberration
Arthur Luna da Fonseca, Kainã Diniz, Paula Borges Monteiro +7
We demonstrate a bistable optical trap by tightly focusing a vortex laser beam. The optical potential has the form of a Mexican hat with an additional minimum at the center. The bi…

Probing the screening of the Casimir interaction with optical tweezers
L. B. Pires, D. S. Ether, B. Spreng +13
We measure the colloidal interaction between two silica microspheres in aqueous solution in the distance range from m to m with the help of optical tweezers. When e…
