UTe₂ Surface Keeps a Charge Pattern Above Its Superconducting Temperature, Pointing to a Pair Density Wave
Researchers observed charge modulations on the UTe₂ surface that persist above the superconducting transition temperature. Differences in the temperatures at which two kinds of patterns vanish, and their dependence on magnetic-field direction, suggest a surface pair density wave. We explain the scope of the observations and interpretation, including prior studies and a null X-ray result.

Laser-Generated Muons Image Lead Behind a 2 m Concrete Wall in Romanian Experiment
At Romania's ELI-NP, artificial muons were used to image a lead object through thick shielding. We look at what was measured, what was estimated by simulation, and the remaining hurdles in imaging time, detectors and portability.

YbSb2, a Type-I Superconductor, Shows Signs of Broken Time-Reversal Symmetry
Muon spin spectroscopy detected a tiny internal magnetic field appearing spontaneously, with no external field applied, in bulk single crystals of the type-I superconductor YbSb2. Here is what the experiment shows, and how far the multi-orbital theory goes.
