- 1Physicists Simulate Particle Creation with Ultracold Atoms▼Simulating Particle Creation with Cold Atoms
Researchers supported by the American Physical Society report a simulation of particle creation using ultracold atoms, reproducing in the lab effects that normally occur in extreme environments such as the early universe or near black holes. The work uses cold atomic gases to model quantum field behavior that is otherwise impossible to observe directly, drawing attention from the physics community.
