Wave-particle dynamics in hydrodynamic quantum analogues
Resumo: The groundbreaking discovery by Yves Couder and Emmanuel Fort (Paris, 2005) led to many works on pilot-wave hydrodynamics. Pilot-wave hydrodynamics originates from bouncing droplets of silicon oil that can levitate over a vibrating bath of the same fluid and be self-propelled by the Faraday waves it generates. Following Couder and Fort, these walking droplets are viewed as a hydrodynamic quantum analogue (HQA) of a wave-particle system. We have deduced the first wave-droplet dynamical system which, through scientific computing, has revealed several new dynamical properties not imagined possible for a classical mechanical system. A series of new articles have originated recently from Nachbin (Chaos 2018) where it was shown for the first time that two oscillators can be correlated at a distance, without any explicit coupling between them. An overview of these recents results will be presented, including those of a recent Nature Comm. Physics paper (June 2022) where we show the cooperative tunneling of two particles.
The 5th-Interpore conference of the Brazilian chapter, will be held from 1 to 2 August 2022 in a fully virtual format with scientific program focusing on advances in the research, methods, and theory of Porous Media in close connection to the topics: Green World, Smart Materials, Oil Science and Synchrotron light, Biosciences, Biorenewables, Nanotechnology.
