    • 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 ...

    • 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 ...

    • Quantitative assessment of non-conservative radiation forces in an optical trap 

      Pesce, G.; Volpe, Giovanni; De Luca, A. C.; Rusciano, G.; Volpe, G. (Institute of Physics Publishing, 2009-05)
      The forces acting on an optically trapped particle are usually assumed to be conservative. However, the presence of a non-conservative component has recently been demonstrated. Here, we propose a technique that permits one ...

    • Step-by-step guide to the realization of advanced optical tweezers 

      Pesce, G.; Volpe, G.; Marago, M. O.; Jones, H. P.; Gigan, S.; Sasso, A.; Volpe, G. (Optical Society of America, 2015-05-05)
      ince the pioneering work of Arthur Ashkin, optical tweezers (OT) have become an indispensable tool for contactless manipulation of micro- and nanoparticles. Nowadays OT are employed in a myriad of applications demonstrating ...
