Evidence for unconventional superconductivity in twisted bilayer graphene [PDF]
The emergence of superconductivity and correlated insulators in magic-angle twisted bilayer graphene (MATBG) has raised the intriguing possibility that its pairing mechanism is distinct from that of conventional superconductors1–4, as described by the ...

Spectroscopic evidence for the superconductivity of elemental metal Y under pressure
Very high applied pressure induces superconductivity with the transition temperature (T c) exceeding 19 K in elemental yttrium, but relatively little is known about the nature of that superconductivity.

Unusual competition of superconductivity and charge-density-wave state in a compressed topological kagome metal [PDF]
Understanding the competition between superconductivity and other ordered states (such as antiferromagnetic or charge-density-wave (CDW) state) is a central issue in condensed matter physics. The recently discovered layered kagome metal AV3Sb5 (A = K, Rb,

Covalent surface modifications and superconductivity of two-dimensional metal carbide MXenes
Modifying MXene surfaces Unlike graphene and transition-metal dichalcogenides, two-dimensional transition-metal carbides (MXenes) have many surface sites that can be chemically modified. Etching of the aluminum layer of a parent MAX phase Ti3AlC2 layered

Reliability Evaluation of Software Filters Applied to Conduction Current in HVDC Power Cables
For design and operation, the conduction current of insulation must be obtained in high-voltage direct current (HVDC) power cables. The measured noise from the environment and equipment can have a significant impact on the reliability of the conduction ...

Superconductivity, superfluidity and quantum geometry in twisted multilayer systems [PDF]
Superconductivity has been observed in moiré systems such as twisted bilayer graphene, which host flat, dispersionless electronic bands. In parallel, theory work has discovered that superconductivity and superfluidity of flat-band systems can be made ...

Superconductivity in the Fullerenes
Intramolecular vibrations strongly scatter electrons near the Fermi-surface in doped fullerenes. A simple expression for the electron-phonon coupling parameters for this case is derived and evaluated by quantum-chemical calculations. The observed superconducting transition temperatures and their variation with lattice constants can be ...

Superconductivity at 250 K in lanthanum hydride under high pressures [PDF]
With the discovery1 of superconductivity at 203 kelvin in H3S, attention returned to conventional superconductors with properties that can be described by the Bardeen–Cooper–Schrieffer and the Migdal–Eliashberg theories.
