The J-structures of the , and clusters have been analyzed, where a, b, c, and d are the components of the inversion splitting in each transition (C-type) (see the figure). It has been found that the inversion splitting becomes smaller with increasing J and with increasing K, both in the state (shown by b-c) and state (shown by a-d). An explanation is given for this finding. [FIGURE
Real-time earthquake warning by using broadband P Waveform
No full text[1] We develop a system, which enables an early warning of earthquake occurrence several seconds before large ground shaking begins. We assume that the vertical displacement of the broadband P waveform can be considered as the far-field source time function of the earthquake. Based upon the seismic moment to source duration relation, we may issue an early warning that an earthquake with magnitude greater than 6 has occurred, when the initial P-wave pulse duration continues for more than 3 seconds. We have applied this algorithm to broadband seismograms recorded at Japanese broadband stations for recent large earthquakes in Japan. We found that it really is possible to assess the occurrence of earthquakes with magnitude greater than 6 within 3 seconds after the P-wave arrival.

Oscillator construction of su(n|m) Q-operators
No full textWe generalize our recent explicit construction of the full hierarchy of Baxter Q-operators of compact spin chains with su(n) symmetry to the supersymmetric case su(n|m). The method is based on novel degenerate solutions of the graded Yang-Baxter equation, leading to an amalgam of bosonic and fermionic oscillator algebras. Our approach is fully algebraic, and leads to the exact solution of the associated compact spin chains while avoiding Bethe ansatz techniques. It furthermore elucidates the algebraic and combinatorial structures underlying the system of nested Bethe equations. Finally, our construction naturally reproduces the representation, due to Z. Tsuboi, of the hierarchy of Baxter Q-operators in terms of hypercubic Hasse diagrams. © 2011 Elsevier B.V

Integrability of the Russian doll BCS model
No full textWe show that integrability of the BCS model extends beyond Richardson's model (where all Cooper pair scatterings have equal coupling) to that of the Russian doll BCS model for which the couplings have a particular phase dependence that breaks time-reversal symmetry. This model is shown to be integrable using the quantum inverse scattering method, and the exact solution is obtained by means of the algebraic Bethe ansatz. The inverse problem of expressing local operators in terms of the global operators of the monodromy matrix is solved. This result is used to find a determinant formulation of a correlation function for fluctuations in the Cooper pair occupation numbers. These results are used to undertake exact numerical analysis for small systems at half-filling
