Electrical effects in superfluid helium. I. Thermoelectric effect in Einstein's capacitor
The Einstein's research ideas on the thermodynamical fluctuational nature of
certain electrical phenomena [1] and the physical nature of the electric
potentials difference U in an electric capacitor at the temperature of T [2]
were proposed in 1906-1907. On the base of Einstein's research ideas, we
explain the recent experimental results [3, 4] and propose the consistent
theory on the physical nature of the electric effects in an electric capacitor
at an action of the second sound standing wave in the superfluid Helium (4He)
and in the rotational torsional mechanical resonator in Helium II. The use of
the Einstein's research approach, based on the consideration of an
interconnection between the thermal, mechanical and electrical fluctuations,
allows us to obtain the quantitative theoretical research results, which are in
a good agreement with the experimental data on the correlations of the
alternate low temperatures difference in the second sound wave, and the
alternate electric potentials difference between the capacitor plates in the
superfluid Helium as well as in the rotational torsional mechanical resonator
in Helium II.Comment: 10 pages, 3 figures
