Gravitational caustics in an atom laser
WebDec 10, 2024 · In experiments at Washington State University, scientists have developed a technique to see these matter wave caustics by placing attractive or repulsive obstacles in the path of a cold atom laser. The results are curving cusps or folds, upward or downward "V" shapes, which the researchers describe in a paper for Nature Communications.
