The results, continuing the legacy of late Columbia professor Aron Pinczuk, are a step toward a better understanding of gravity. A team of scientists from Columbia, Nanjing University, Princeton, and the University of Munster, writing in the journal Nature, have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material.

In 2015, a class of two-dimensional materials called the transition metal dichalcogenides (TMDs) entered the scientific limelight for their ability to produce just one particle of light at a time. Such single-photon emission was a natural, and somewhat random, ability in TMDs with structural defects—missing atoms here and there, or a wrinkle where the crystal should have been straight and even.
