Revisiting the charge-density-wave superlattice of 1-TiSe
Wei Wang, Patrick Liu, Lijun Wu +4
A number of intriguing phenomena, including exciton condensation, orbital ordering, and emergence of chirality, have been proposed to accompany charge-density-wave (CDW) formation…
Charge density waves and pinning by lattice anisotropy in 214 cuprates
Xiao Hu, Pedro M. Lozano, Feng Ye +5
The detection of static charge density waves (CDWs) in LaSrCuO (LSCO) with x 0.12 at relatively high temperatures has raised the question of what lattice fea…
Strongly-overdoped LaSrCuO: Evidence for Josephson-coupled grains of strongly-correlated superconductor
Yangmu Li, A. Sapkota, P. M. Lozano +20
The interpretation of how superconductivity disappears in cuprates at large hole doping has been controversial. To address this issue, we present an experimental study of single-cr…
Tuning from failed superconductor to failed insulator with magnetic field
Yangmu Li, J. Terzic, P. G. Baity +5
Do charge modulations compete with electron pairing in high-temperature copper-oxide superconductors? We investigated this question by suppressing superconductivity in a stripe-ord…
Direct observation of dynamic charge stripes in La2-xSrxNiO4
S. Anissimova, D. Parshall, G. D. Gu +8
The insulator-to-metal transition continues to be a challenging subject, especially when electronic correlations are strong. In layered compounds, such as La2-xSrxNiO4 and La2-xBax…
Proximity-induced high-temperature superconductivity in topological insulators Bi2Se3 and Bi2Te3
Parisa Zareapour, Alex Hayat, Shu Yang F. Zhao +11
Interest in the superconducting proximity effect has been reinvigorated recently by novel optoelectronic applications as well as by the possible emergence of the elusive Majorana f…
Effects of charge inhomogeneities on elementary excitations in La_{2-x}Sr_xCuO_4
S. R. Park, A. Hamann, L. Pintschovius +7
Purely local experimental probes of many copper oxide superconductors show that their electronic states are inhomogeneous in real space. For example, scanning tunneling spectroscop…
Electron-phonon anomaly related to charge stripes: static stripe phase versus optimally-doped superconducting La1.85Sr0.15CuO4
D. Reznik, L. Pintschovius, M. Fujita +3
Inelastic neutron scattering was used to study the Cu-O bond-stretching vibrations in optimally doped La1.85Sr0.15CuO4 (Tc = 35 K) and in two other cuprates showing static stripe o…
Microstructure and Structural Defects in MgB2 Superconductor
Y. Zhu, L. Wu, V. Volkov +6
We report a detailed study of the microstructure and defects in sintered polycrystalline MgB2. Both TEM and x-ray data reveal that MgO is the major second-phase in our bulk samples…
