Effect of the next-nearest neighbor hopping on the stability and band structure of the incommensurate phases in the cuprates
Using a spin-rotation invariant version of the slave-boson approach we investigate the relative stability and band structure of various incommensurate phases in the cuprates. Our findings obtained in the Hubbard model with next-nearest neighbor hopping −t/t ≃ 0.15, as appropriate for the La2−xSrxCuO4 family, support the formation of diagonal (vertical) stripe phases in the doping regime x = 1/1...
متن کاملSlow Fracton Modes in Antiferromagnetic Correlations of High-t C Superconductors
(Dated: December 7, 1999) In cuprate superconductors superconductivity develops as a unique crossover between the two extremes characterizing these compounds, an antiferromagnetic (AF) Mott insulator phase, on one side, and a non-superconducting itinerant metal on the other. The hole doping tunes a cuprate inside such a broad spectrum of phases. Numerous inelastic neutron scattering studies on ...
متن کاملStripes and superconductivity in one-dimensional self-consistent model
We show that many observable properties of high temperature superconductors can be obtained in the frameworks of one-dimensional self-consistent model with included superconducting correlations. Analytical solutions for spin, charge and superconductivity order parameters are found. The ground state of the model at low hole doping is a spin-charge solitonic superstructure. Increasing of doping l...
متن کاملLiquid crystal phases of two-dimensional dipolar gases and Berezinskii-Kosterlitz-Thouless melting
Liquid crystals are phases of matter intermediate between crystals and liquids. Whereas classical liquid crystals have been known for a long time and are used in electro-optical displays, much less is known about their quantum counterparts. There is growing evidence that quantum liquid crystals play a central role in many electron systems including high temperature superconductors, but a quanti...
متن کاملDisorder induced stripes in d-wave superconductors
Stripe phases are observed experimentally in several copperbased high-T c superconductors near 1/8 hole doping. However, the specific characteristics may vary depending on the degree of dopant disorder and the presence or absence of a low-temperature tetragonal phase. On the basis of a Hartree–Fock decoupling scheme for the t–J model, we discuss the diverse behavior of stripe phases. In particu...
