    • Experimental investigation of critical Casimir forces in binary liquid mixtures by blinking optical tweezers 

      Magazzù A.; Schmidt F.; Callegari A.; Gambassi A.; Dietrich S.; Volpe G. (OSA - The Optical Society, 2017)
      We investigate, for the first time and by blinking optical tweezers, the effects of critical Casimir forces (CCFs) on the free dynamics of a pair of spherical colloidal particles, immersed in binary liquid mixtures upon ...
    • Nonadditivity of critical Casimir forces 

      Callegari A.; Paladugu S.; Tuna Y.; Barth L.; Dietrich S.; Gambassi A.; Volpe G. (OSA - The Optical Society, 2017)
      We provide the first experimental evidence of nonadditivity for critical Casimir forces: the force that two colloidal particles exert together on a third one differs from the sum of the forces they exert separately. © 2017 OSA.
