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

Electrical transport through a normal-metal/superconductor contact at biases smaller than
the energy gap can occur via the reflection of an electron as a hole of opposite wave vector …

The microscopic theory of superconductivity worked out by Bardeen, Cooper, and Schrieffer
led to a fundamental understanding of the phenomenon. However, this theory does not …

We provide an analytic solution for the mean-field equations and for the relevant physical
quantities at the Gaussian level, in terms of the complete elliptic integrals of the first and …

The theoretical description of the anomalous properties of the pseudogap phase in the
underdoped region of the cuprate phase diagram lags behind the progress in spectroscopic …

High-temperature superconductivity in the copper-oxide ceramics remains an unsolved
problem because we do not know what the propagating degrees of freedom are in the …

We analyze the interplay between superconductivity and the formation of bound pairs of
fermions (BCS-BEC crossover) in a 2D model of interacting fermions with small Fermi …

The achievement of Bose–Einstein condensation in ultra-cold vapours of alkali atoms has
given enormous impulse to the study of dilute atomic gases in condensed quantum states …

The strongly interacting Hubbard model on the square lattice is reduced to the low energy
plaquette boson fermion model (PBFM). The four bosons (an antiferromagnon triplet and a d …

The modulated structure of the CuO 2 plane in Bi 2 Sr 2 CaCu 2 O 8+ y superconductor has
been solved by Cu K-edge anomalous x-ray diffraction. The displacement of Cu ions along …
