Underdoped high-Tc superconductors are frequently characterised by a temperature, T*,
below which the normal-state pseudogap opens. Two different “phase diagrams” based on …

In solid-state physics two different paradigms are typically applied. The first is a local picture,
in which one visualizes the quantum states of electrons in atomic orbitals or at impurity …

We study a simple model of a two-dimensional s-wave superconductor in the presence of a
random potential as a function of disorder strength. We first use the Bogoliubov–de Gennes …

We present scanning tunneling spectroscopy measurements of the CuO chain plane in YBa
2 Cu 3 O 6+ x, showing a∼ 25 meV gap in the local density of states (LDOS) filled by …

Doping and disorder are inseparable in the superconducting cuprates. Assuming the
simplest possible disordered doping, we construct a semiphenomenological model and …

The nanometer-scale gap inhomogeneity revealed by recent scanning tunnel microscope
images of Bi 2 Sr 2 CaCu 2 O 8+ x (BSCCO) surface suggests that the “gap coherence …

Since its discovery in 1986, understanding both the ground state and excited states of high
temperature superconductivity (HTSC) has been one of the main challenges in modern …

Atomic-resolution scanning tunneling spectroscopy is used to study the spectrum of
quasiparticle states in superconducting Sr2RuO4. The measured temperature dependence …

Scanning tunneling spectroscopy is used to study the dispersive wave vectors of the local-
density-of-states modulations in near-optimal Bi _2 Sr _2 CaCu _2 O _8+δ. Atomic …

The scanning probe techniques (SPM) are the most important research tool for nanoscience
and nanostructured materials. Among the various methods developed in the literature …
