Pressure-Tuned Superconducting Dome and Persistent Charge-Density-Wave Order in NdSeTe₂. [PDF]

Adv Sci (Weinh)
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Emergent Magnetism, Heavy Electrons, and Pressure-Induced Reentrant Superconductivity in the Iron Substituted 4d Transition-Metal Sulfides. [PDF]

Adv Sci (Weinh)
This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

High-Temperature Superconductivity: The Explanation [PDF]

Physica Scripta, 2011
Soon after the discovery of the first high temperature superconductor by Georg Bednorz and Alex Mueller in 1986 the late Sir Nevill Mott answering his own question "Is there an explanation?" [Nature v 327 (1987) 185] expressed a view that the Bose-Einstein condensation (BEC) of small bipolarons, predicted by us in 1981, could be the one.

Projected BCS theory for the unification of antiferromagnetism and strongly correlated superconductivity

Physical Review Research, 2022
A close connection between antiferromagnetism and superconductivity is at the core of high-temperature superconductivity. Here, we put forward the projected BCS theory for the unification of antiferromagnetism and strongly correlated superconductivity ...

High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W₂N Thin Films. [PDF]

Adv Sci (Weinh)
Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...

High-temperature superconductivity in hydrides: experimental evidence and details [PDF]

, 2022
Since the discovery of superconductivity at 200 K in H3S [1] similar or higher transition temperatures, Tcs, have been reported for various hydrogen-rich compounds under ultra-high pressures [2].

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.
