Dimensional crossover in quasi-one-dimensional and high-Tc superconductors
The one-dimensional electron gas exhibits spin-charge separation and power-law spectral responses to many experimentally relevant probes. Ordering in a quasi-one-dimensional system is necessarily associated with a dimensional crossover, at which sharp quasiparticle peaks, with small spectral weight, emerge from the incoherent background. Using methods of Abelian bosonization, we derive asymptot...
متن کاملQuasi-one-dimensional superconductors: from weak to strong magnetic field
We discuss the possible existence of a superconducting phase at high magnetic field in organic quasione-dimensional conductors. We consider in particular (i) the formation of a Larkin-OvchinnikovFulde-Ferrell state, (ii) the role of a temperature-induced dimensional crossover occuring when the transverse coherence length ξz(T ) becomes of the order of the lattice spacing, and (iii) the effect o...
متن کاملLarkin-Ovchinnikov-Fulde-Ferrell state in quasi-one-dimensional superconductors.
The properties of a quasi-one-dimensional (quasi-1D) superconductor with an open Fermi surface are expected to be unusual in a magnetic field. On the one hand, the quasi-1D structure of the Fermi surface strongly favors the formation of a non-uniform state (Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) state) in the presence of a magnetic field acting on the electron spins. On the other hand, a magne...
متن کاملQuasi - One - Dimensional Riemann Problems
We study two-dimensional Riemann problems with piecewise constant data. We identify a class of two-dimensional systems, including many standard equations of compressible ow, which are simpliied by a transformation to similarity variables. For equations in this class, a two-dimensional Riemann problem with sectorially constant data becomes a boundary-value problem in the nite plane. For data lea...
متن کاملMagnetic Properties of Unconventional Superconductors
The article reviews recent developments on magnetic properties of superconductors with anisotropic Cooper pairing. In particular, we show how the concept of broken symmetries is applied to the investigation of the mixed state in superconductors with a multicomponent order parameter. Starting from the phenomenological description in the framework of the generalized Ginzburg-Landau theory, we dis...
