Time-resolved magneto-optical imaging measurements show that an ac current enables the vortex matter in YBa2Cu3O7-x thin films to reorganize into two coexisting steady states of driven vortex motion with different characteristics: a quasi-static
disordered glassy state in the sample interior and a dynamic state of plastic motion near the edges. Finite-element calculations
consistent with the critical state model show good agreement with the measured field profiles in the quasi-static state but
predict a larger hysteretic behavior in the dynamic state.

We propose a new experiment employing an earthbound ring laser interferometer to search for evidence of a preferred frame in the Universe. It would yield a measurement of or a tight new constraint on the value of the PPN parameter α1. 相似文献

Conservative methods for the Toda lattice equations 总被引:1,自引:0,他引:1
We are concerned with the numerical integration of the Todalattice equations by using different conservative methods. Numericalexperiments suggest that the global error for isospectral schemesdecreases exponentially with time but it is almost constantfor either symplectic or more general integrators. We providea theoretical explanation for these experimental findings. 相似文献
