Researchers advance quantum material mapping and superconductor control

Researchers have achieved significant milestones in the study of quantum materials and superconductivity. An international collaboration involving the Max Planck Institute and Rice University has mapped the electronic structures of 9,000 two-dimensional materials. This catalog identifies over 1,600 candidates for “twisting,” a technique known as twistronics where stacking and angling material layers unlocks novel electronic behaviors and potential quantum simulators.

In a separate development, researchers at the Research Center for Materials Nanoarchitectonics (MANA) in Japan have discovered that atomic-scale surface steps can act as guides for superconducting vortices. The team found that these quantum objects move more than 1,000 times more easily along these one-atom-high steps than across them. This mechanism allows for the directional control of vortex motion in two-dimensional superconductors, which is critical for the development of future low-power electronic technologies.
