Superconductivity-Insensitive Order at q∼1/4 in Electron-Doped Cuprates
One of the central questions in the cuprate research is the nature of the normal state that develops into high-temperature superconductivity (HTSC). In the normal state of hole-doped cuprates, the existence of a charge density wave (CDW) is expected to ...

General relativity and the cuprates [PDF]
We add a periodic potential to the simplest gravitational model of a superconductor and compute the optical conductivity. In addition to a superfluid component, we find a normal component that has Drude behavior at low frequency followed by a power law fall-off.

Quench–drive spectroscopy of cuprates
We calculate the nonlinear signal of a cuprate superconductor when subjected to a quenching and a driving field, showing transient features of the generated higher harmonics, as well as the enhancement of coherence in incoherent Cooper pairs.

Theory of Underdoped Cuprates [PDF]
We develop a slave-boson theory for the t-J model at finite doping which respects an SU(2) symmetry -- a symmetry previously known to be important at half filling. The mean field phase diagram is found to be consistent with the phases observed in the cuprate superconductors, which contains d-wave superconductor, spin gap, strange metal, and Fermi ...

Nodeless superconductivity in cuprates with Ba [PDF]
In this work, zero-temperature phase diagrams of cuprates with Ba$$_2$$CuO$$_3$$-type CuO chain structure are investigated. The projective symmetry group analysis is employed in the strong coupling limit, and the one-loop renormalization group with ...

Nature of extrinsic and intrinsic self-trapping (ST) of charge carriers in cuprates have been studied theoretically. The binding energies and radii of the extrinsic and intrinsic large polarons and bipolarons in cuprates are calculated variationally ...

Possible superconductivity from incoherent carriers in overdoped cuprates
The non-superconducting state of overdoped cuprates is conjectured to be a strange metal comprising two distinct charge sectors, one governed by coherent quasiparticle excitations, the other seemingly incoherent and characterized by non-quasiparticle ...

Stripes and superconductivity in cuprates [PDF]
Holes doped into the CuO2 planes of cuprate parent compounds frustrate the antiferromagnetic order. The development of spin and charge stripes provides a compromise between the competing magnetic and kinetic energies. Static stripe order has been observed only in certain particular compounds, but there are signatures which suggest that dynamic stripe ...

Electronic structure of ladder cuprates [PDF]
We study the electronic structure of the ladder compounds (SrCa)CuO 14-24-41 and SrCuO 123. LDA calculations for both give similar Cu 3d-bands near the Fermi energy. The hopping parameters estimated by fitting LDA energy bands show a strong anisotropy between the t_perp t_par intra-ladder hopping and small inter-ladder hopping.
