    • Active particles in complex and crowded environments 

      Bechinger, C.; Di Leonardo, R.; Löwen, H.; Reichhardt, C.; Volpe, G. (American Physical Society, 2016-11)
      Differently from passive Brownian particles, active particles, also known as self-propelled Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy from their environment and converting it ...
    • Brownian gyrator: an experimental realization 

      Soni, Jalpa; Argun, A.; Dabelow, L.; Bo, S.; Eichhorn, R.; Pesce, G.; Volpe, Giovanni (OSA, 2017)
      We present an experimental realization of a minimal heat engine in the form of a single Brownian particle, performing gyrating motion by systematic torque generation due to dissipation from two different heat baths in a ...
    • Controlling active brownian particles in complex settings 

      Velu, Sabareesh K. P.; Pinçe, Erçağ; Callegari, Agnese; Elahi, Parviz; Gigan, S.; Volpe, Giovanni; Volpe, G. (OSA, 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 ...
    • Long-term influence of fluid inertia on the diffusion of a Brownian particle 

      Pesce, G.; Volpe, G.; Volpe, G.; Sasso, A. (American Physical Society, 2014)
      We experimentally measure the effects of fluid inertia on the diffusion of a Brownian particle at very long time scales. In previous experiments, the use of standard optical tweezers introduced a cutoff in the free diffusion ...
    • Optical manipulation with random light fields: from fundamental physics to applications 

      Volpe, G.; Gigan, S.; Volpe, Giovanni (OSA, 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 ...
