Electronic transport in condensed matter

Using laser-excited photoelectron emission microscope (laser-PEEM) we found that the nematic stiffness in iron-based superconductors significantly increases as the systems become strange metals, suggesting that spin–orbital fluctuations enhance the stiffness of electronic nematicity.

Superconductivity

Millimeter-sized single crystals of a trilayer cuprate superconductor (Hg,Re)Ba₂Ca₂Cu₃O_8+δ that exhibits the highest superconducting transition temperature under ambient pressure, were grown reproducibly and safely.
