Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid ³He and
solutions of ³He in ⁴He systems confined to nano-channels. In the case of pure ballistic flow at very low
temperature conductance will be quantized in units of 2 m²/h. We show that these steps should be sensitive to
increases in temperature. We also use a random scattering matrix simulation to study flow with diffusive
wall scattering. Universal conductance fluctuations analogous to those seen in electron systems should then
be observable. Finally we consider the possibility of the cross-over to a one-dimensional system at sufficiently
low temperature where the system could form a Luttinger liquid. |
