Cascade sets the stage for superconductivity in magic-angle twisted bilayer graphene

Princeton researchers used scanning tunneling microscopy to observe what happens when they add electrons to magic-angle twisted bilayer graphene. They observed a cascade of transitions in the electronic properties, patterns that could help unlock how superconductivity emerge in these materials. Continue Reading →

Princeton scientists discover surprising quantum effect in an exotic superconductor

Superconductors are already in use in various capacities, but newer iron-based superconductors are an active area of investigation. Researchers led by a Princeton team have studied what happens to the superconducting nature of these materials when impurities are added. The results shed light on how superconductivity behaves in these materials Continue Reading →

Princeton physicists discover topological behavior of electrons in three-dimensional magnetic material

In a room-temperature magnet, researchers find behaviors of electrons that mimic massless particles and anti-particles. Continue Reading →

Mysterious Majorana quasiparticle is now closer to being controlled for quantum computing

As mysterious as the Italian scientist for which it is named, the Majorana particle is one of the most compelling quests in physics. Its fame stems from its strange properties – it is the only Continue Reading →

For infection-fighting cells, a guideline for expanding the troops

T cells are like the special ops forces of the immune system, detecting and killing infected cells. When a new threat is detected, the cells ramp up from just a few sentry cells to a Continue Reading →
