    • Controlling active brownian particles in complex settings 

      Velu S.K.P.; Pinçe E.; Callegari A.; Elahi P.; Gigan S.; Volp G.; Volp G. (OSA - The Optical Society, 2017)
      We show active Brownian particles (passive Brownian particles in a bacterial bath) switches between two long-term behaviors, i.e. gathering and dispersal of individuals, in response to the statistical properties of the ...
    • Engineering particle trajectories in microfluidic flows using speckle light fields 

      Volpe, G.; Volpe, G.; Gigan, S. (SPIE, 2014)
      Optical tweezers have been widely used in physics, chemistry and biology to manipulate and trap microscopic and nanoscopic objects. Current optical trapping techniques rely on carefully engineered setups to manipulate ...
    • Optical manipulation with random light fields: From fundamental physics to applications 

      Volpe G.; Gigan, S.; Volpe G. (OSA - The Optical Society, 2015)
      Speckles are random light fields that share some universal statistical properties. Because of this, they can be used to perform deterministic optical manipulation tasks on a Brownian particle as well as control its diffusion ...
    • Uncertainty and dissipation 

      Carcaterra, A.; Akay, Adnan (Katholieke Universiteit Leuven, 2012-09)
      This paper discusses the question of the energy confinement in mechanical structures in the light of the uncertainties affecting the natural frequencies of the system. More precisely, recent studies have shown that energy ...
