Electronic structure and superconductivity of the non-centrosymmetric Sn4As3

New Journal of Physics, 2020
In a superconductor that lacks inversion symmetry, the spatial part of the Cooper pair wave function has a reduced symmetry, allowing for the mixing of spin-singlet and spin-triplet Cooper pairing channels and thus providing a pathway to a non-trivial ...

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 ...

Non‐Fermi‐Liquid Behavior of Superconducting SnH4

Advanced Science, 2023
The chemical interaction of Sn with H2 by X‐ray diffraction methods at pressures of 180–210 GPa is studied. A previously unknown tetrahydride SnH4 with a cubic structure (fcc) exhibiting superconducting properties below TC = 72 K is obtained; the ...

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: 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.
