Moiré superconductivity

Annals of Physics, 2020
Recently, superconductivity was discovered at very low densities in slightly misaligned graphene multilayers. Surprisingly, despite extremely low electronic density (about $10^{-4}$ electrons per unit cell), these systems realize strong-coupling superconductivity, with the transition temperature being a large fraction of the Fermi energy ($T_c\sim 0.1

Ambient‐Pressure Superconductivity Onset at 10 K and Robust Tc under High Pressure in TiNbTaN3 Medium‐Entropy Nitride

Advanced Science, EarlyView.
The first observation of superconductivity in a bulk MEN TiNbTaN3 with Tc ≈ 10 K at ambient pressure and the electronic specific heat coefficient γ(H) exhibits nonlinear H‐dependence behavior, which is similar to other well‐studied multigap superconductors is reported.

Anticrossing of A Plasmonic Nanoresonator Mode and A Single Quantum Dot at Room Temperature

Advanced Science, EarlyView.
Using the oxygen‐dependent blue‐shift in CdSe/ZnS quantum dots, their emission is deterministically tuned across the resonance of a plasmonic slit resonator, achieving a complete anticrossing with a 100 meV Rabi splitting. By pre‐characterizing the uncoupled states, strong coupling at room temperature is confirmed.

Achieving Complex Nanostructures: The Role of Hydrogen in Controlling Mechanical Alloying and Microstructure Evolution in the TiVZrNbHf‐Cu System

Advanced Science, EarlyView.
This study highlights the drastic influence hydrogen has on the microstructure evolution during severe plastic deformation. High‐pressure torsion of a TiVZrNbHf‐Cu composite results in mechanical alloying and subsequent amorphization, whereas replacing the high entropy alloy with the corresponding hydride stabilizes a two‐phase microstructure.
