Numerical Study of Impurity Effects on Quasiparticles within S-wave and Chiral P-wave Vortices

The impurity problems within vortex cores of two-dimensional s-wave and chiral p-wave superconductors are studied numerically in the framework of the quasiclassical theory of superconductivity and self-consistent Born approximation under a trial form of the pair potential. The dispersion and impurity scattering rate (the inverse of the relaxation time) of the Andreev bound state localized in vortex cores are deduced from the angular-resoloved local density of states. The energy dependence of the impurity scattering rates depends on the pairing symmetry; particularly, in the chiral p-wave vortex core where chirality and vorticity have opposite sign and hence the total angular momentum is zero, the impurities are ineffective and the scattering rate is vanishingly small. Owing to the cancellation of angular momentum between chirality and vorticity, the chiral p-wave vortex core is similar to locally realized s-wave region and therefore non-magnetic impurity is harmless as a consequence of Anderson's theorem. The results of the present study confirm the previous results of analytical study (J. Phys. Soc. Jpn. {\bf 69} (2000) 3378) in the Born limit.Comment: 8pages, 9figures, submitted to J. Phys. Soc. Jp

Lateral vibration data of an actual 18-story timber-concrete hybrid building

The dataset provided in this repository represents the raw data of the lateral vibration collected through on-site tests on an 18-story timber-concrete hybrid building. The dataset consists of the time-series velocity data obtained by microtremor measurement and human-powered excitation tests.Servo velocity sensors and a data acquisition system composed of an A/D converter, a DC amplifier and a laptop were used to measure the velocity data. The velocity in the longitudinal and the transverse directions of the building were recorded with a sampling rate of 200 Hz in all the tests.Each Microsoft Excel Spreadsheet (.xlsx) file contains a ‘Data’ sheet and a ’Plot’ sheet. The time-series velocity data are listed in the Data-sheet, while the velocity-time curves are shown in the Plot-sheet. In the Data-sheet, the first column represents the time. The following columns represent the velocity of each sensor. The unit for the time and the velocity are second (s) and cm/s, respectively.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
