Seminar: the cost of remembering

Notre Dame University, IN (USA) - Oct. 2nd 2018

ICAND 2018 - NiPS presentation on "The cost of remembering"

 

 

Aug. 5-9, Maui (USA)

International Conference on Applications in Nonlinear Dynamics (www.icand2018.org).

Luca Gammaitoni presents recent work at NiPS on the Physics of Computing with an invited talk entitled: The Cost of Remembering.

In 1961, Rolf Landauer pointed out that resetting a binary memory requires a minimum energy of kBT ln(2). However, once written, any memory is doomed to loose its content if no action is taken. To avoid memory losses, a refresh procedure is periodically performed. In this talk we present a theoretical and experimental study of sub-kBT system to evaluate the minimum energy required to preserve one bit of information over time. Two main conclusions are drawn:

i) in principle the energetic cost to preserve information for a fixed time duration with a given error probability can be arbitrarily reduced if the refresh procedure is performed often enough;

ii) the Heisenberg uncertainty principle sets an upper bound on the memory lifetime: no memory can last forever.

Micro energy from bio cell at the Soft robotics conference

 

Livorno, April 24, 2018

L. Gammaitoni presents recent work done at NiPS Laboratory, in collaboration with L. Catacuzzeno and F. Franciolini, of the Biology depatment of the University of Perugia, on energy harvesting from biological cells.

The work, perfomed at NiPS by F. Orfei, A. Di Michele and L. Gammaitoni, deals with the possibility to use a biological cell as a source of electrical energy for powering micro robots embedded in living organism.

EnABLES Kick-off meeting, at the Bedford Hotel & Congress Centre, in Brussels

Brussels Jan 31st 2018

 

 

We just held the EnABLES Kick-off meeting, at the Bedford Hotel & Congress Centre, in Brussels.

At the meeting participated representatives from all the 9 partners.

NiPS Laboratory was represented by Francesco Orfei and Luca Gammaitoni.

EnABLES is a 4 year EC funded project EnABLES that will integrate key European research infrastructures (RIs) in powering the Internet of Things (IoT).

6 research institutes together with 5 knowledge hubs of excellence will address the long term needs of
energy management in self-powered smart sensor systems as required by IoT innovation. To enable truly
‘invisible’, unobtrusive and self-powered (autonomous) wireless devices a key challenge is to bridge the
gap between capturing ‘ambient’ energy supply from energy harvesting sources (EH), integrating new
devices for energy storage (ES) and taking into account the micro-power management (MPM)
requirements for miniaturised system operation.

NiPS celebrates the 2017 Physics Nobel Prize to gravitational wave detection

 

Perugia 6/10 2017

Virgo Perugia group, part of NiPS laboratory, celebrated the 2017 Nobel Prize in Physics awarded to three american scientists (Weiss, Thorne, Barish) for gravitational wave detection.
The Virgo Perugia group is part of the international scientific collaboration LIGO-Virgo that realized the first gravitational wave obesrvation, made on 14 September 2015 and  announced on 11 February 2016.

The Virgo Perugia group was founded in 1990 and has worked on the construction of the Virgo interferometer, test masses suspension system, since then. Specifically, the experise of the NiPS group is on thermal noise and associated implications for the functioning of the gravitational wave interferometer.
