c-axis penetration depth and interlayer conductivity in the thallium-based cuprate superconductors

The c-axis Josephson plasmons in optimally doped single-layer and bilayer high-Tc cuprates Tl2Ba2CuO6 and Tl2Ba2CaCu2O8 have been investigated using infrared spectroscopy. We observed the plasma frequencies for these two compounds at 27.8 and 25.6 cm respectively, which we interpret as Josephson resonances across the TlO blocking layers. No maximum in the temperature dependence of the c-axis co...

Continuous 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...

Optical conductivity and string theory

In this note we summarize some facts about optical conductivity and the corresponding holographic models attempting to describe it. 1. Optical conductivity The optical properties of solids provide an important tool to study their microscopic dynamics. In certain materials with strong electron correlations a quantum critical state of matter can occur. In this situation the system looks on averag...

Multiband 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...
