Critical Quadrupole Fluctuations and Collective Modes in Iron Pnictide Superconductors

V. K. Thorsmølle, M. Khodas, Z. P. Yin +4

The multiband nature of iron pnictides gives rise to a rich temperature-doping phase diagram of competing orders and a plethora of collective phenomena. At low dopings, the tetrago…

Point-contact tunneling spectroscopy measurement of Cu $_{x}$ TiSe $_{2}$ : disorder-enhanced Coulomb effects

Katherine Luna, Phillip M. Wu, Justin S. Chen +2

We performed point-contact spectroscopy tunneling measurements on Cu $_{x}$ TiSe $_{2}$ bulk with $x = 0.02$ and $0.06$ at temperatures ranging from $T = 4 - 40$ K and observe a suppression in…

Short-range cluster spin glass near optimal superconductivity in BaFe $_{2 - x}$ Ni $_{x}$ As $_{2}$

Xingye Lu, David W. Tam, Chenglin Zhang +9

High-temperature superconductivity in iron pnictides occurs when electrons are doped into their antiferromagnetic (AF) parent compounds. In addition to inducing superconductivity,…

Superconducting states of a J1-J2-K model for iron pnictides

Rong Yu, Andriy H. Nevidomskyy

We study the symmetry and strength of the superconducting pairing in a two-orbital t-J1-J2-K model for iron pnictides using the salve boson mean-field theory. We show that the near…
