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

Rietveld refinement of natural fluorapatite from ultra-high pressure eclogite
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.

Why non-superconducting metallic elements become superconducting under high pressure [PDF]
We predict that simple metals and early transition metals that become superconducting under high pressures will show a change in sign of their Hall coefficient from negative to positive under pressure. If verified, this will strongly suggest that hole carriers play a fundamental role in `conventional' superconductivity, as predicted by the theory of ...

The fundamental role of superconducting quasiparticle coherence in cuprate superconductors [PDF]
Within the kinetic energy driven superconducting mechanism, we study the interplay between superconductivity and the nodal and antinodal superconducting quasiparticle coherences in cuprate superconductors, and find the s-wave superconducting transition temperature is heavily suppressed by the antinodal superconducting quasiparticle coherence, while the
