A model of the interior heavy nucleus is proposed. Some experiments suggest that proton pair and neutron are moving in a strongly correlated manner inside (alpha-correlation). To describe this, proton-neutron interaction extended from pairing force to many-body force. Accordingly, BCS must be go beyond Gorkov decoupling order incorporate As result, comparing state, more stable state where both alpha correlation developed obtained. This clarifies an interrelation between paring...
The origin of the stability triangular incommensurate (IC) phase gamma -brass ( -Cu1-xZnx) is discussed. In a very narrow concentration range 0.586<x<0.60, -CuZn exhibits long-period inversion antiphase domain structure with spacing as long 2000 AA. order to elucidate such an extremely IC structure, authors develop phenomenological treatment based on Landau-Ginzburg free energy functional. parameter established in terms particular phonon mode prototype BCC phase. By introducing...
We present a comprehensive study on the nonequilibrium properties of superconducting nanoconstriction junctions in steady-state and time-dependent dynamic regimes. By measuring current-voltage characteristics single constriction micro-superconducting quantum interference devices with nanobridges, we observe series distinct voltage-step jumps dissipative state, which are associated appearance excess current. Through detailed analysis, identify different mechanisms that contribute to...
For pt.I, see ibid., vol.18, p.1371-86 (1988). An electron microscopic study has revealed the presence of a strong deformation triangular IAPD pattern in gamma -brass. Using free-energy functional associated with phase variables pattern, authors demonstrate invariance topology pattern. They can regard system to be medium, which they call 'phase medium', and also obtain effective elastic constants medium. The observed been qualitatively reproduced by calculating strain field medium under...
