Gubbio Scienza: Micro Energy 2017, NiPS Summer School 2017 & much more

During the last ten days, the town of Gubbio (Italy) has held a lot of activities on micro energies. For scientists from all over the world, but even for families and kids.  
The two main events were:   

  • NiPS Summer School 2017 - Energy Harvesting: models and applications, June 30 - July 3, 2017
  • Micro Energy 2017 Conference: 3 - 7 July, 2017

But Gubbio Scienza has been much more!
Please, visit the Gubbio Scienza Facebook page and the Gubbio Scienza website and discover all the activities of the last 10 days.

Adi Bulsara form SPAWAR System Center meets L. Gammaitoni to discuss future collaboration



April 22, 2017 - Tempe (AZ) USA

Dr. Adi Bulsara from SPAWAR System Center, San Diego, meets L. Gammaitoni from NiPS to discuss future collaboration.

NiPS Laboratory has a long collaboration record with SPAWAR on sensor devices and nonlinear stochastic dynamics. During the meeting were presented recent development on nonlinear energy harvesting for sensing applications at micro and nano scales. These results will be most probably presented at the next international conference to be held in Gubbio, Italy, on July 3-7 2017.

Igor Neri (right in the picture) and Luca Gammaitoni (left in the picture) represented NiPS at the kick off meeting of the new European project OPRECOMP.
OPRECOM is is a 4-year research project co-funded under the EU 7th Framework Horizon 2020 – Re Program Future and Emerging Technologies (FET) Proactive Initiative: emerging themes and communities. FET aims to go beyond the conventional boundaries of ICT and ventures into uncharted areas, often inspired by and in close collaboration with other scientific disciplines.
OPRECOMP aims to build an innovative, reliable foundation for computing based on transprecision analytics.

Seminar: Sergio Ciliberto, A protocol for reaching equilibrium arbitrary fast


Perugia, 6 Sept. 2016


NiPS Seminar: A protocol for reaching equilibrium arbitrary fast

Prof. Sergio Ciliberto
Laboratoire de Physique de ENSL

Universitè de Lyon


When  a control parameter of a system  is suddenly changed, the accessible phase space changes too and  the system needs its characteristic relaxation time to reach the final equilibrium distribution.  An important and relevant question is whether it is possible to travel from an equilibrium state to another in an arbitrary  time, much shorter  than the natural relaxation time.

Such strategies are reminiscent of those worked out in the recent field of Shortcut to Adiabaticity, that aims at developing protocols, both in quantum and in classical regimes, allowing the system to move as fast as possible from one equilibrium position to a new one, provided that there exist an adiabatic transformation relating the two. Proof of principle experiments have been carried out for isolated systems.

Instead  in  open system the reduction of the relaxation time, which is frequently desired and necessary, is often obtained by complex feedback processes. In this talk, we present  a protocol,named Engineered Swift Equilibration (ESE), that shortcuts time-consuming relaxations. We tested experimentally this protocol  on  a Brownian particle trapped in an optical potential first and then on an AFM cantilever. We show that applying a specific driving, one can reach equilibrium in an arbitrary short time.  We also estimate  the energetic cost to get such a time reduction.

Beyond its fundamental interest, the ESE method paves the way for applications in micro and nano devices, in high speed AFM, or in monitoring mesoscopic chemical or biological process.
