Deviation from the Wiedemann-Franz law induced by nonmagnetic impurities in overdoped La_{2-x}Sr_{x}CuO_{4}

X. F. Sun, B. Lin, X. Zhao +4

To investigate the validity of the Wiedemann-Franz (WF) law in disordered but metallic cuprates, the low-temperature charge and heat transport properties are carefully studied for…

Comment on "Low-temperature phonon thermal conductivity of single-crystalline Nd_{2}CuO_{4}: Effects of sample size and surface roughness" by Li et al.

X. F. Sun, Yoichi Ando

In this Comment, we show that the experimental data reported by Li {\it et al.} (Phys. Rev. B {\bf 77}, 134501 (2008)) do not support the phonon specular reflection at low temperat…

Pair breaking versus symmetry breaking: Origin of the Raman modes in superconducting cuprates

N. Munnikes, B. Muschler, F. Venturini +9

We performed Raman experiments on superconducting $B i_{2} S r_{2} (C a_{1 - x} Y_{x}) C u_{2} O_{8 + δ}$ (Bi-2212) and $YB a_{2} C u_{3} O_{6 + x}$ (Y-123) single crystals. These results i…

Electronic Origin of the Inhomogeneous Pairing Interaction in the High-Tc Superconductor Bi2Sr2CaCu2O8+d

Abhay N. Pasupathy, Aakash Pushp, Kenjiro K. Gomes +7

Identifying the mechanism of superconductivity in the high-temperature cuprate superconductors is one of the major outstanding problems in physics. We report local measurements of…

Large magnetothermal conductivity in GdBaCo_{2}O_{5+x} single crystals

X. F. Sun, A. A. Taskin, X. Zhao +2

To study the effects of paramagnetic spins on phonons, both the in-plane and the c-axis heat transport of GdBaCo_{2}O_{5+x} (GBCO) single crystals are measured at low temperature d…
