This review presents recent developments in the understanding of how impurities influence
the electronic states in the bulk properties of superconductors. The focus is on …

Tunneling spectroscopy has played a central role in the experimental verification of the
microscopic theory of superconductivity in classical superconductors. Initial attempts to apply …

The transport of a small amount of liquid on a solid is not a simple process, owing to the
nature of the contact between the two phases. Setting a liquid droplet in motion requires non …

Although the crystal structures of the copper oxide high-temperature superconductors are
complex and diverse, they all contain some crystal planes consisting of only copper and …

In materials with strong local Coulomb interactions, simple defects such as atomic
substitutions strongly affect both macroscopic and local properties of the system. A …

We study the pairing symmetry of a two-orbital J 1-J 2 model for FeAs layers in oxypnictides.
We show that the mixture of an intraorbital unconventional sx 2 y 2∼ cos⁡(kx) cos⁡(ky) …

We use the quasiclassical theory of superconductivity to calculate the electronic contribution
to the thermal conductivity. The theory is formulated for low temperatures when heat …

Magnetic interactions and magnetic impurities are destructive to superconductivity in
conventional superconductors. By contrast, in some unconventional macroscopic quantum …

We propose that the energy-dependent spatial modulation of the local density of states seen
by Hoffman et al.[Science 297, 1148 (2002)] is due to the scattering interference of …

The formation of bound states at surfaces of materials with an energy gap in the bulk
electron spectrum is a well known physical phenomenon. At superconductor surfaces …
