“…(8)) is invariant under translations and spin SU (2) and charge U (1) transformations, no CDW, SDW, or superconducting long range order can exist in its ground state. Therefore, in a quasi-one dimensional system made out of an array of coupled 1DEG's, a transition into an ordered state necessarily signifies a dimensional crossover at which, owing to relevant interchain couplings, phases of individual chains lock together [23,149]. The ultimate low temperature fate of the system is fixed by the identity of the first phase to do so.…”

“…In the opposite limit of strong repulsive interactions between electrons, the normal state has high kinetic energy. It is thus possible to conceive of a kinetic energy driven mechanism of superconductivity, in which the strong frustration of the kinetic energy is partially relieved upon entering the superconducting state [18][19][20][21][22][23][24]. Such a mechanism does not require subtle induced attractions, but derives directly from the strong repulsion between electrons.…”

The Physics of Superconductors

PrefaceIt is the purpose of this paper to explore the theory of high temperature superconductivity. Much of the motivation for this comes from the study of cuprate high temperature superconductors. However, we do not focus in great detail on the remarkable and exciting physics that has been discovered in these materials. Rather, we focus on the core theoretical issues associated with the mechanism of high temperature superconductivity. Although our discussions of theoretical issues in a strongly correlated superconductor are intended to be self contained and pedagogically complete, our discussions of experiments in the cuprates are, unfortunately, considerably more truncated and impressionistic.Our primary focus is on physics at intermediate temperature scales of order T c (as well as the somewhat larger "pseudogap" temperature) and energies of order the gap maximum, ∆ 0 . Consequently (and reluctantly) we have omitted any detailed discussion of a number of fascinating topics in cuprate superconductivity, including the low energy physics associated with nodal quasiparticles, the properties of the vortex matter which results from the application of a magnetic field, the effects of disorder, and a host of material specific issues. This paper is long enough as it is!

Spectrum of boson fields and two-point correlators are analyzed in a quantum bar system (a superlattice formed by two crossed interacting arrays of quantum wires), with short range interwire interaction. The standard bosonization procedure is shown to be valid, within the two wave approximation. The system behaves as a sliding Luttinger liquid in the vicinity of the Γ point, but its spectral and correlation characteristics have either 1D or 2D nature depending on the direction of the wave vector in the rest of the Brillouin zone. Due to interwire interaction, unperturbed states, propagating along the two arrays of wires, are always mixed, and the transverse components of the correlation functions do not vanish. This mixing is especially strong around the diagonals of the Brillouin zone, where transverse correlators have the same order of magnitude as the longitudinal ones.
