Specific heat evidence for bulk s-wave gap symmetry of optimally electron-doped Pr(1.85)Ce(0.15)CuO(4-y) superconductors.

Journal of physics. Condensed matter : an Institute of Physics journal

Zhao GM, Wang J.
PMID: 21403275
J Phys Condens Matter. 2010 Sep 08;22(35):352202. doi: 10.1088/0953-8984/22/35/352202. Epub 2010 Aug 02.

We reanalyze specific heat data for optimally electron-doped Pr(1.85)Ce(0.15)CuO(4-y) superconductors. The magnetic field dependence of the electronic specific heat in the vortex state does not support d-wave gap symmetry but agrees quantitatively with an s-wave theory. Furthermore, the field...

PMID: 27534898
Sci Rep. 2016 Aug 18;6:31824. doi: 10.1038/srep31824.

In low-dimensional electron systems, charge density waves (CDW) and superconductivity are two of the most fundamental collective quantum phenomena. For all known quasi-two-dimensional superconductors, the origin and exact boundary of the electronic orderings and superconductivity are still attractive problems....

Downregulation of tumor protein 53-inducible nuclear protein 1 expression in hepatocellular carcinoma correlates with poor prognosis.

Oncology letters
