SUMMARY:From quantum electronics to quantum nanofluidics\, R. G. Herb 
 Condensed Matter Seminar\, Guillaume Gervais\, McGill University
DESCRIPTION:It has long been known that the flow of electric charges i
 n an electrical circuit maintained by a voltage drop is analogous to t
 he fluidic mass flow in a pipe maintained under a pressure differentia
 l. In electronic devices\, and at small scale\, lowering the dimension
 ality can have drastic consequences on the flow of charges in electron
 ic circuit.  In two dimension\, series of quantized states appear with
  quantized Hall resistance\,  competing with electron crystals and oth
 er many-body states. In one dimension\, the conductance of a wire itse
 lf becomes quantized in unit of 2e^2/h due to confinement and quantum 
 effects. In this talk\, I will present an overview of recent results f
 or the quantum electronics studied in ultra-clean semiconductor materi
 als with an emphasis on possible non-abelian quantum states. I will al
 so discuss our endeavour and progress to measure the mass flow of a qu
 antum fluid confined into a nanopipe where\, in analogy with the quant
 um electronics in one dimension\, the conductance of the pipe should b
 ecome quantized in unit of 2m^2/h.
