Recent Developments

Recent developments in understanding the nature of surface electronic structure focused on illuminating the electronic origin of reconstruction of the Mo (001) surface have been reviewed. The long-standing disputes between two competing theoretical models, the charge density wave model and the local bonding model, for the driving mechanism of the reconstructional transition seem to be resolved by recent experimental evidences favoring the Peierls-type 2kF instabilities with significant matrix element effects. Details of recent experimental and theoretical findings for the surface electronic bands are discussed briefly with an emphasis placed on characterizing the surface states and their roles in the reconstruction.

This study investigates the use of second-order irregular waves for estimating loads on dropped objects. The theory for the irregular nonlinear wave model is integrated into a motion prediction model to simulate the falling process of a dropped cylinder under irregular waves. Through frequency analysis, the simulated irregular waves are transformed into wave spectrum by fast Fourier transform and compared with the target wave spectrum. A good agreement between simulated wave spectrum and target wave spectrum indicates the validity of the irregular nonlinear wave model. The effects of cylinder mass density, wave amplitude and initial wave phase on the trajectory and terminal conditions of dropped cylindrical object are systematically investigated, and the simulated results are compared with those induced by regular waves.

The Magnetic Field

Predictions of the charge density wave (CDW) model for potassium are tested by high-field induced torque experiments. The CDW model is described to show the open orbits on the Fermi surface of potassium with a CDW. Expressions for the induced torque are developed in terms of the resistivity and other parameters of the sample. The induced torque as a function of magnetic field direction shows sharp structure above 3–4 T with more than 20 peaks in 180° rotation. The peaks have the character of open orbits and the large number is predicted by the CDW model. The magnetic field, sample orientation, and temperature dependences of induced torque are also investigated. The magnetic field dependence agrees with that expected from open orbits with magnetic breakdown. However, the open orbits that would cause the induced torque peaks are not in directions predicted by the CDW model. Variation of induced torque with temperatures between 1.4 and 2.1 K can be explained by some of the features of the model although the observed changes are larger than those predicted. The conclusion is that the CDW model explains many of the properties of the high-field induced torque structure.
