Fragmented magnetism

A team of researchers from Boston College, MIT, and UC Santa Barbara has discovered an elusive atomic-scale magnetic signal in a Mott insulator material as it undergoes a transition from insulator to metal. The study uses spin-polarizing scanning tunneling microscopy to detail the underlying physics at the atomic level.

Lessons in learning

A new Harvard study shows that students in 'active learning' classrooms learn more than they think, contradicting long-held beliefs about the effectiveness of traditional lectures. The study found that students felt like they learned more from lectures but actually scored higher on tests following active learning sessions.

A trailblazer

Elisabeth Gwinn, a professor at UC Santa Barbara, has been awarded the AAAS Lifetime Mentor Award for her decades-long commitment to mentoring underrepresented students in physics. Her work has transformed her department and improved the lives of countless students.

Beyond the black hole singularity

Loop quantum gravity allows physicists to extend gravitational physics beyond general relativity's limitations, enabling the analysis of black hole interiors. The theory predicts a repulsive force that can overwhelm classical gravity, potentially resolving the information paradox at black holes.

Half moons and pinch points: Same physics, different energy

Researchers at OIST Graduate University have developed a unified theory explaining the formation of pinch points and half moons in frustrated magnets. The theory reveals that these patterns arise from the same underlying physics, with pinch points representing equilibrium and half moons signifying violation of local conservation laws.
