Josephson interferometry in magic-angle twisted trilayer graphene reveals asymmetric interference and field-sweep hysteresis below about 0.8 K, beneath the superconducting onset near 2 K.
Why it matters. Phase-sensitive probes help connect interference measurements to candidate superconducting symmetries.
Evidence limits. The authors interpret these signatures as consistent with broken time-reversal symmetry; they do not uniquely establish a chiral pairing state.

X-ray spectroscopy of protected (La,Pr)3Ni2O7 films links superconductivity to coherent interlayer orbital hybridization, with oxygen content and epitaxial strain tuning the electronic states.
Why it matters. A material-specific link between orbital coherence and superconductivity guides comparisons between nickelate samples.
Evidence limits. This film-specific evidence supports a multiorbital interpretation but does not by itself settle the pairing mechanism across nickelate families.

Monolayer Bi-2201 retains superconductivity with one CuO2 plane, while controlled oxygenation reveals an intermediate anomalous metal and unusual scaling near the superconductor–insulator transition.
Why it matters. A single-plane platform helps isolate how dimensionality and oxygen tuning affect cuprate transport.
Evidence limits. The reported phase behavior concerns this material and tuning protocol; its zero-temperature interpretation is inferred from finite-temperature measurements.
