    • 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 ...
    • Engineering particle trajectories in microfluidic flows using speckle light fields 

      Volpe, G.; Volpe, Giovanni; 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 ...
    • Engineering sensorial delay to control phototaxis and emergent collective behaviors 

      Mijalkov, M.; McDaniel, A.; Wehr, J.; Volpe, G. (American Physical Society, 2016-01)
      Collective motions emerging from the interaction of autonomous mobile individuals play a key role in many phenomena, from the growth of bacterial colonies to the coordination of robotic swarms. For these collective behaviors ...
    • Non-Boltzmann stationary distributions and nonequilibrium relations in active baths 

      Argun, A.; Moradi A.-R.; Pinçe, E.; Bagci, G. B.; Imparato, A.; Volpe, G. (American Physical Society, 2016-12)
      Most natural and engineered processes, such as biomolecular reactions, protein folding, and population dynamics, occur far from equilibrium and therefore cannot be treated within the framework of classical equilibrium ...
    • Numerical simulation of optically trapped particles 

      Volpe, G.; Volpe, Giovanni (SPIE, 2014)
      Some randomness is present in most phenomena, ranging from biomolecules and nanodevices to financial markets and human organizations. However, it is not easy to gain an intuitive understanding of such stochastic phenomena, ...
    • On the modeling of CO2 EUA and CER prices of EU-ETS for the 2008–2012 period 

      Gürler, Ü.; Yenigün, D.; Çağlar, M.; Berk, E. (John Wiley and Sons, 2016)
      Increased consumption of fossil fuels in industrial production has led to a significant elevation in the emission of greenhouse gases and to global warming. The most effective international action against global warming ...
    • 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 ...
