The quasi-particle density of states (DOS) at temperatures from 4.2 K to high above the critical temperature Tc is obtained by inversion directly from the experimentally measured superconductor-insulator-superconductor (SIS) tunneling data performed

Tunneling spectra of Bi2Sr2CaCu2 O 8 + δ intrinsic Josephson junctions with different doping are analyzed and reproduced using a d-wave Eliashberg formalism in a wide temperature range below T c , from which the pairing glue spectral function α 2 F

We propose to extract the quasiparticle density of states (DOS) of the superconductor directly from the experimentally measured superconductor-insulator-superconductor junction tunneling data by applying the maximum entropy method to the nonlinear sy

The new simple and effective grid remeshing method on crack propagation in brittle materials is successfully introduced which is under uniaxial compression. Numerical analysis is applied to brittle materials of a single pre-existing crack considering

A tight-binding (TB) treatment with the inclusion of d orbitals is applied to the electronic structures of graphitic tubes. The results show that the high angular moment bases in TB scheme are necessary to account the severe curvature effect in ultra

Using the density-matrix renormalization-group (DMRG) technique, we carry out a large scale numerical calculation far the S=2 antiferromagnetic Heisenberg (AFH) chain. We obtain the magnetization curve of S =2 chain near the critical field. The corre

The ground-state cohesive energy per electron of the composite fermion (CF) Fermi sea, the Laughlin state, and the charge density wave (CDW) at higher Landau levels (LL's) are computed. It is shown that whereas for $ng~2 \mathrm{LL},$ the CDW state i

We study the current noise spectra of a tunnel junction of a metal with strong pairing phase fluctuation and a superconductor. It is shown that there is a characteristic peak in the noise spectrum at the intrinsic Josephson frequency $\omega_J=2eV$ w

The magnetic susceptibility and specific heat of the one-dimensional S=1 bilinear-biquadratic Heisenberg model are calculated using the transfer matrix renormalization group. By comparing the results with the experimental data of ${\rm LiVGe_2O_6}$ m
