The interest of this paper centers on fabrication and characterization and modeling of vortices in high temperature superconducting thin films. As a first step, the magnetic vertices of the superconducting matrix were modeled. As a second, Bi-Sr-Ca-C

We show how a kink state can be generated in a single crystal region of a high-Tc superconductor, if it has d-wave pairing. At the center of the kink there exists a sizable number of midgap states, so this kink state can be confirmed by observing a z

If high- T c superconductors have d -wave pairing, midgap states must exist at most surfaces and interfaces, and, in a more subtle way, also at unitary impurity sites. These states of topological origin have many novel consequences, each of which is

Based on an extended Hubbard model, we present calculations of both the local (i.e., single-site) and spatially averaged differential tunneling conductance in d-wave superconductors containing nonmagnetic impurities in the unitary limit. Our results

On the basis of the Keldysh method of nonequilibrium systems, we develop a theory of electron tunneling in normal-metal--superconductor junctions. By using the tunneling Hamiltonian model (being appropriate for the tight-binding systems), the tunneli

The quasiparticle resonant states around a single nonmagnetic impurity with unitary scattering in a d-wave superconductor is studied by solving the Bogoliubov-de Gennes equations based on a t-J model. Both the spatial variation of the order parameter

An update of a previous review on the many effects and novel consequences of the midgap states predicted to exist in d-wave superconductors is given. Four works done by the author and his collaborators are reviewed with a bit more details, but many w
