Briefings

A Munich and Utrecht physics team analyzed electrical noise in cuprate superconductors to identify the pseudogap, a missing electron state. Milan Allan and Ingmar Swart led the study published in Science on November 8, 2026, revealing that current flow reveals the vanishing electrons responsible for the mystery. The study provides a new mechanism for understanding high-temperature superconductivity but leaves the exact cause of the pseudogap unresolved.

Key points

• Physicists led by Milan Allan and Ingmar Swart analyzed electrical noise in cuprate superconductors to identify the pseudogap, a missing electron state.
• The study was published in Science on November 8, 2026, revealing that current flow reveals the vanishing electrons responsible for the mystery.

Context

Cuprates superconductors were discovered in the late 1980s to operate at higher temperatures using liquid nitrogen, yet the underlying mechanism remains unclear. This study attempts to resolve the mystery by examining the pseudogap phenomenon.

Limitations

The evidence is limited to a single Science study from November 2026. The specific causal link between the electrical noise and the pseudogap is not fully established, and the study does not provide a complete explanation for the high-temperature superconductivity mechanism.
