In experimental sciences, random processes often place a fundamental limit on the achievable measurement resolution. A well known example is the Johnson noise voltage across a resistor. In this paper, we describe observations of the spontaneous transfer of heat in two equilibrium systems: one...
We have extended the earlier work of Kafkalidis, Klinich, and Tough (KKT) on the effect of nonuniform flow on superfluid turbulence. The same high aspect ratio rectangular cross section flow channel is used as before, but now reversed to produce converging flow. Temperature difference data are...
A first-principle quantum statistical mechanical theory is used to study the properties of thick liquid4He films absorbed to the weakly binding substrates: Li, Na, and Cs. Values for the liquid-gas and solid-liquid surface energies are determined. By fitting, at long wavelengths, the film's...
We report on heat capacity measurements of the spin-Peierls compound CuGeO3 under magnetic fields between 0 and 22 teslas. We have determined the magnetic phase diagram between the three different phases (U=uniform,I=incommensurate,D=dimerised) of this system, unknown up to now forH>14 T, and...
We report a newly observed phenomenon of nucleation and first order phase transition, from superfluid helium-four, in which a metastable solid phase nucleates and grows from the overpressured liquid in preference to the stable phase. We discuss these results in terms of the difference in...
We report on a theoretical investigation of liquid helium-4 at negative pressures. For normal liquid helium we estimate the thermodynamic functions for negative pressure via extrapolation of measurements made for positive pressures. We determine the free energy as a function of density and...
Transmission of very slow neutrons through superfluid liquid helium has been measured from 8 to 15 Å neutrons at temperatures between 0.45 K and 2.4 K. The results are compared with the single phonon emission and absorption theory.
We present data of the elastic properties of the Laves phase compound CeRu2 in the normal and superconducting state obtained from ultrasound measurements. In the temperature range between the superconducting transition temperature of 6.1 K and 300 K we used a deformation potential coupling...
The scattering of zero-sound phonons by incoherent spin fluctuations (SF) and its influence on the velocity dispersion and attenuation of zero sound in exchange enhanced Fermi-liquid are considered.
We demonstrate that in the presence of pinning a simple relation exists between Nernst and Seebeck coefficients and the resistivity tensor, based on the vortex equation of motion and the two-fluid model. Thus the combination of the electric and thermoelectric transport experiments can be used to...
