Mechanically extensional–deformation of ultra-high molecular weight polyethylene (UHMWPE) was examined by using polarization terahertz (THz) spectroscopy as well as X-ray diffraction (XRD) analysis. Due to the B 1u lattice translational mode, a THz

Pb(Zr0.05Ti0.95)O3/(La,Sr)CoO3 thin films were prepared by pulsed laser deposition (PLD) on SrTiO3(001) substrates. Phase transition behavior of Pb(Zr0.05Ti0.95)O3 (PZT) was investigated using high temperature X-ray diffraction (HT-XRD) and high-temp

Molecular dynamics simulations of molten (La1/3, K)Cl at 1123 K have been performed in order to investigate the correlation between simulated dynamical properties such as the self-exchange velocity (ν), the self-diffusion coefficient (D) and the ele

We clarify the difference among potential models so far proposed to explain mass spectra of heavy-light mesons via transformations of the vacuum. Applying our idea to Q quarkonium, we obtain the extra term, 1/r2 with positive coefficient, other than

Yttria-stabilized zirconia (YSZ) films were prepared on Si(111) substrates with a slow deposition rate. X-ray diffraction clearly showed epitaxial growth of YSZ(111) film on Si(111), the X-ray scan of 3-fold symmetry confirmed single domain YSZ(111)

Partial decay widths of the heavy-light mesons, $D, D_s, B,$ and $B_s$, emitting one chiral particle ($\pi$ or $K$) are evaluated in the framework of a relativistic potential model. Decay amplitudes are calculated by keeping the Lorentz invariance as

We study the decay properties of a heavy-light meson. We reformulate the decay amplitudes for the heavy-light systems and find a new way to calculate decay rates. Applying this formulation, we find a new sum rule for the radiative decays of one heavy

Fermion one-loop corrections to the commutators of the gauge field, the electric field, and the charge density with the total Hamiltonian are evaluated by the Bjorken-Johnson-Low method in chiral gauge theories. It turns out that individual terms of
