DESCRIPTION:Speaker: Baptiste Coquinot\nhosted by Mikhail Lemeshko\nAbstrac
 t: An electronic current driven through a conductor can induce a current i
 n another conductor through the famous Coulomb drag effect. Similar phenom
 ena have been reported at the interface between a moving fluid and a condu
 ctor\, but their interpretation has remained elusive. I will present our r
 ecent theoretical work\, which predicts that a globally neutral liquid can
  generate an electronic current in the solid wall along which it flows [1]
 \, building on the idea of solid-liquid quantum friction [2]. This hydrody
 namic Coulomb drag originates from both the Coulomb interactions between t
 he liquids charge fluctuations and the solids charge carriers\, and the li
 quid-electron interaction mediated by the solids phonons\, consistently wi
 th experimental observations [3]. Our results provide a roadmap for contro
 lling nanoscale liquid flows at the quantum level. In particular\, we pred
 ict a fluidic equivalent of electron tunnelling\, termed flow tunnelling: 
 a flowing liquid may transfer momentum to another liquid through a solid w
 all. We directly observe this phenomenon in semi-classical molecular dynam
 ics simulations\, paving the way to a wealth of nanofluidic applications i
 nspired by condensed matter physics.
