Short CV of the speaker : Pierre Verlot is assistant professor in Quantum Science and Technology at the University of Nottingham. His main research focuses on developing new nano-optomechanical
and nano-electromechanical approaches with the aim to investigate the Fundamental Measurement Principles and their technological consequences.
Abstract : Nanomechanical systems generally denote mechanical resonators with one or several minute dimensions, below the micron scale. They have recently raised increased attention : they are now rapidly spreading in a growing number of scientific domains and are often cited as one of the major upcoming technological revolution.
This recent trend relies on two major aspects. First, on the fundamental side, decreasing the mass of a mechanical resonator enables to increase its sensitivity towards external interactions. On a technological side, besides an increased integrability, the miniaturization of mechanical probes gives access to unprecedentedly high spatial resolution for the exploration of new scientific phenomena and advanced technological possibilities.
The development of nanomechanical systems faces a number of challenges. Reducing the dimensions often faces the imperfections of the fabrication processes, resulting in degraded mechanical properties, and henceforth limited benefit. Besides, novel detection methods must be developed, ensuring both high sensitivity and limited backaction effects. Additionally, the very small masses of nanomechanical systems makes them indifferently sensitive to all kind of driving phenomena, with a dynamical behaviour prone to be strongly nonlinear, representing as many technical and theoretical difficulties.
In these seminars, I will provide both fundamental and technological motivation of the on-going research in nanomechanics. I will introduce the challenges and corresponding solutions being developed, enabling a comprehensive review of the state of the art. I will introduce a few relevant examples of this technology, before setting up some of the most exciting perspective of the field.
