For various sample geometries (slabs, cylinders, spheres, hypercubes), de Gennes' boundary condition parameter b is used to study its effect upon the transition temperature T c of a superconductor. For b > 0 the order parameter at the surface is decr

The Ginzburg-Landau (GL) theory is recast using a Hamiltonian involving the complete kinetic energy density which requires that the surface energy must contain a term \nabla |\psi|^2 to support superconducting (SC) states. The GL equations contain tw

Using the full nonlinear Ginzburg-Landau equations, we study the behaviour of a particular superconducting micronetwork near its transition temperature: a circular loop connected to an infinitely long wire by a branch of length L. In this mesoscopic

The modified two-fluid model of the microwave surface impedance Zs5Rs1iXs of cuprates is discussed in Refs. 1‐6 with regard to the temperature dependence of Zs(T )i n the ab plane for different optimally doped high-Tc single crystals. Here, we appl

Bulk mechanisms of the integer quantum Hall effect are investigated using a noninteracting electron gas confined to the $(x,y)$ plane and quasiconfined in x by a harmonic-oscillator potential characterized by frequency ${f}_{o}.$ The integer filling
