Moiré Polariton Provides a New Path to Quantum Nonlinearity
By integrating an atomically-thin superlattice with a microcavity, we prepare a system to manipulate the quantum state with versatile flexibility, suggesting a new path to ultralow energy nonlinear photonic devices.
Ultra-high-energy gamma rays in the Cygnus Cocoon
What is the source of the highest-energy cosmic rays in our Galaxy? We report here the observation of the ultra-high-energy gamma-ray emission from a stellar superbubble in the Cygnus region, powered by the massive stellar complex called Cygnus OB2 in an attempt to answer this question.
