Dome-shaped magnetic order competing with high-temperature superconductivity at high pressures in FeSe. [PDF]

Nat Commun, 2016
The coexistence and competition between superconductivity and electronic orders, such as spin or charge density waves, have been a central issue in high transition-temperature (Tc) superconductors.

Calculation and Optimization of Resistive Wall and RF Cavity Impedance in Medium Energy Diffraction Limit Storage Ring

Yuanzineng kexue jishu, 2022
In the diffraction limit storage ring, the size of the vacuum chamber was greatly reduced compared with the third-generation synchronous light source due to the high-gradient small-aperture magnet, and the impedance of ring is significantly increased ...

High-Temperature Superconductivity [PDF]

Physical Review Letters, 1987
Upon cooling metallic conductors, in general their resistance becomes smaller. In 1911, the Dutch physicist H. Kamerlingh Onnes observed that the resistance of mercury disappeared entirely below a temperature of -269?C (1). He had discovered the first superconductor. In the absolute temperature scale, -269?C corresponds to +4.3 degrees K.
