Surface contribution to the specific heat of he II filmsSpringer Science and Business Media LLC - Tập 10 - Trang 225-230 - 1973
S. L. Chan
The surface contribution to the specific heat of saturated and unsaturated He II films has been considered. The temperature dependence of the surface-contributed specific heat is found to depend on the range of temperatures as well as the film thickness under consideration. A comparison with earlier results is made, and it is found that those results are not consistent with the specific heat contr...... hiện toàn bộ
Studies of the dielectric constant in solid H2,4He, and NeSpringer Science and Business Media LLC - Tập 25 - Trang 353-368 - 1976
D. G. Haase, H. Meyer
Measurements of the static dielectric constant ε and of the resulting polarizability αCM defined by the Clausius-Mosotti relation are reported for several molecular solids under conditions of quasiconstant density. The range of measurements was between 0.4 and about 15 K, and pressures up to about 1 kbar were used. In solid H2, the changes of α as a function of ortho concentration are reported at ...... hiện toàn bộ
Electrical Noise in a TES as a Resistively Shunted Conducting JunctionSpringer Science and Business Media LLC - - 2012
A. Kozorezov, A. A. Golubov, D. D. E. Martin, P. A. J. de Korte, M. A. Lindeman, R. A. Hijmering, J. van der Kuur, H. F. C. Hoevers, L. Gottardi, M. Y. Kupriyanov, J. K. Wigmore
We present results of the analysis of electrical noise in a transition edge sensor (TES) as a resistively shunted conducting junction (the RSJ model). We derive an expression for the spectral density of voltage fluctuations taking into account weak superconductivity of a TES. We analyse and discuss differences in voltage noise in a TES compared to the familiar situation for the Josephson junction....... hiện toàn bộ

Pyramid-type antireflective subwavelength structures for large-diameter (
$$> 30\hbox { cm}$$
) silicon lenses are promising for broadband astronomical observations. The refractive index and dielectric loss tangent of the lens material, columnar cr...... hiện toàn bộ
