BEC of Free Bosons on Networks
Taku Matsui
We consider free Bosons hopping on a network(infinite graph). The condition for Bose-Einstein condensation is given in terms of the random walk on a graph. In case of periodic latt…
Explosive fragmentation of thin ceramic tube using pulsed power
Hiroaki Katsuragi, Satoshi Ihara, Haruo Honjo
This study experimentally examined the explosive fragmentation of thin ceramic tubes using pulsed power. A thin ceramic tube was threaded on a thin copper wire, and high voltage wa…
Brownian sheet and reflectionless potentials
Setsuo Taniguchi
The bijectivity of the mapping, which is represented as expectation, from a family of Gaussian measures parametrized by linear combinations of Dirac measures to the space of classi…
Pressure-induced valence change in the rare earth metals:The case of Praseodymium
Naoyuki Tateiwa, Akitoshi Nakagawa, Kazuhiko Fujio +2
The rare earth metal praseodymium (Pr) transforms from the d-fcc crystal structure (Pr-III) to {}-U one (Pr-IV) at 20 GPa with a large volume collapse ( = 0.16), whi…
Determination of S17 from 8B breakup by means of the method of continuum-discretized coupled-channels
K. Ogata, S. Hashimoto, Y. Iseri +2
The astrophysical factor for 7Be(p,γ)8B at zero energy, S17(0), is determined from an analysis of 208Pb(8B, p+7Be)208Pb at 52 MeV/nucleon by means of the method of continuum-discre…
Regularized product expressions of higher Riemann zeta functions
Tetsuya Momotani
As a generalization of [KMW], we introduce a higher Riemann zeta function for an abstract sequence. Then we explicitly determine its regularized product expression.
