Stripes and superconductivity in cuprates [PDF]
Physica B: Condensed Matter, 2012 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 ...

Hidden magnetism at the pseudogap critical point of a cuprate superconductor [PDF]
Nature Physics, 2019 The nature of the pseudogap phase of hole-doped cuprate superconductors is still not understood fully. Several experiments have suggested that this phase ends at a critical hole doping level p *, but the nature of the ground state for lower doping is ...

MRS Proceedings, 1996 AbstractLayered copper-oxide superconductors exhibit the highest critical transition temperatures of any materials. Yet all of the known double perovskites A′A″B′B″O6 containing copper have a random or rock salt distribution of the B cations with the exception of the unique layered arrangement found in La2CuSnO6.

Electronic structure of ladder cuprates [PDF]
Physical Review B, 1998 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.

Physical Review Letters, 2020 High T_{c} superconductors show a rich variety of phases associated with their charge degrees of freedom. Valence charges can give rise to charge ordering or acoustic plasmons in these layered cuprate superconductors.

Magnetic field–induced pair density wave state in the cuprate vortex halo [PDF]
Science, 2018 Decoding the halo pattern Magnetic fields can cause the formation of vortices in a superconductor. In cuprate superconductors, the vortex cores are surrounded by “halos,” where the density of electronic states exhibits a checkerboard pattern.

Macroscopic evidence for quantum criticality and field-induced quantum fluctuations in cuprate superconductors [PDF]
, 2007 We present macroscopic experimental evidence for field-induced microscopic quantum fluctuations in different hole- and electron-type cuprate superconductors with varying doping levels and numbers of CuO$_2$ layers per unit cell.

Vanishing nematic order beyond the pseudogap phase in overdoped cuprate superconductors [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Understanding the character of the enigmatic pseudogap phase is a fundamental problem in the physics of the cuprate superconductors. Key to this problem is identifying what types of order, if any, are associated with pseudogap.

Perspective on the phase diagram of cuprate high-temperature superconductors
Nature Communications, 2016 Cuprate superconductors show critical temperatures over 100 K, below which current flows without resistance. Here, the authors show how this temperature is set by material chemistry, leading to a reinterpretation of the cuprate phase diagram and ...
