High temperature superconductivity in sulfur and selenium hydrides at high pressure [PDF]

European Physical Journal B : Condensed Matter Physics, 2015
Due to its low atomic mass, hydrogen is the most promising element to search for high-temperature phononic superconductors. However, metallic phases of hydrogen are only expected at extreme pressures (400 GPa or higher).

Magnetic field induced charge order in cuprate superconductors: an explanation by spin-vortex-induced loop currents [PDF]

Journal of Physics: Conference Series, 2018
We present a possible explanation for a recently observed magnetic field induced charge order in cuprate superconductors (Edkins et al. arXiv:1802.04673 [cond-mat.supr-con]).

Superconductivity without Fe or Ni in the phosphides BaIr2P2 and BaRh2P2 [PDF]

, 2009
Heat capacity, resistivity, and magnetic susceptibility measurements confirm bulk superconductivity in single crystals of BaIr$_2$P$_2$ (T$_c$=2.1K) and BaRh$_2$P$_2$ (T$_c$ = 1.0 K). These compounds form in the ThCr$_2$Si$_2$ (122) structure so they are

Rietveld refinement of natural fluorapatite from ultra-high pressure eclogite

, 2008
superconductor at high pressure due to the high density of states at the Fermi level. Matsuoka et al [2] followed Feng’s work and indeed found CaLi2 become a superconductor at 11 GPa.

Proximity induced superconductivity by Bi in topological $Bi_2Te_2Se$ and $Bi_2Se_3$ films: Evidence for a robust zero energy bound state possibly due to Majorana Fermions

, 2011
Point contact conductance measurements on topological $Bi_2Te_2Se$ and $Bi_2Se_3$ films reveal a signature of superconductivity below 2-3 K. In particular, critical current dips and a robust zero bias conductance peak are observed.

Type-I superconductivity in Al$_6$Re

, 2019
While the pure elements tend to exhibit Type-I rather than Type-II superconductivity, nearly all compound superconductors are Type-II, with only a few known exceptions.

Theoretical study of impurity-induced magnetism in FeSe [PDF]

, 2018
Experimental evidence suggests that FeSe is close to a magnetic instability, and recent scanning tunneling microscopy (STM) measurements on FeSe multilayer films have revealed stripe order locally pinned near defect sites. Motivated by these findings, we
