متن کاملEffect of proximity coupling of chains and planes on the penetration-depth anisotropy in YBa2Cu3O7.
We calculate the penetration depth λ in the a, b and c directions for a simple model of YBa2Cu3O7. In this model there are two layers—representing a CuO2 plane and a CuO chain—per unit cell. There is a BCS–like pairing (both s wave and d wave are considered) interaction localised in the CuO2 planes. The CuO chains become superconducting at temperatures lower than Tc because of their proximity t...
متن کاملContinuous penetration depth
We present a new measure for computing continuous penetration depth between two intersecting rigid objects. We generate a set of samples in the configuration space, precompute an approximation of the contact space for two intersecting objects using binary classification techniques, and construct a bijective mapping between the spherical space and the precomputed contact space. For a given in-co...
متن کاملFast Penetration Depth Computation and its Applications
In this paper, we highlight our past experiences on fast penetration depth computation and its applications in different areas such as physically-based animation, 6DOF haptic rendering and robot motion planning.
متن کاملMultiband model for penetration depth in MgB2
The results of first-principles calculations of the electronic structure and the electron-phonon interaction in MgB2 are used to study theoretically the temperature dependence and anisotropy of the magnetic-field penetration depth. The effects of impurity scattering are essential for a proper description of the experimental results. We compare our results with experimental data and we argue tha...
