Superfluidity of He Confined in Nano-Porous Media
Keiya Shirahama, Keiichi Yamamoto, Yoshiyuki Shibayama
We have examined superfluid properties of He confined to a nano-porous Gelsil glass that has nanopores 2.5 nm in diameter. The pressure-temperature phase diagram was determined…
The limits of nested subclasses of several classes of infinitely divisible distributions are identical with the closure of the class of stable distributions
Makoto Maejima, Ken-iti Sato
It is shown that the limits of the nested subclasses of five classes of infinitely divisible distributions on , which are the Jurek class, the Goldie-Steutel-Bondesson class,…
Phase diagram of nuclear "pasta" and its uncertainties in supernova cores
Hidetaka Sonoda, Gentaro Watanabe, Katsuhiko Sato +2
We examine the model dependence of the phase diagram of inhomogeneous nulcear matter in supernova cores using the quantum molecular dynamics (QMD). Inhomogeneous matter includes cr…
Hölder continuity of the IDS for matrix-valued Anderson models
Boumaza Hakim
We study a class of continuous matrix-valued Anderson models acting on $L^{2}(\R^{d})\otimes \C^{N}$. We prove the existence of their Integrated Density of States for any …
Thermodynamic Evidence for Nanoscale Bose-Einstein Condensation in ^4He Confined in Nanoporous Media
Keiichi Yamamoto, Yoshiyuki Shibayama, Keiya Shirahama
We report the measurements of the heat capacity of ^4He confined in nanoporous Gelsil glass that has nanopores of 2.5-nm diameter at pressures up to 5.3 MPa. The heat capacity has…
Expressions of algebra elements and transcendental noncommutative calculus
Hideki Omori, Yoshiaki Maeda, Naoya Miyazaki +1
Ideas from deformation quantization are applied to deform the expression of elements of an algebra. Extending these ideas to certain transcendental elements implies that $\frac{1}{…
