Meet the Quadruplon: Scientists Discover a New Four-Body Quantum Particle

Scientists have discovered a new four-body quasi-particle, the quadruplon, in a 2D semiconductor. Using laser experiments and advanced theory, they identified unique spectral features unexplained by existing models, confirming the quadruplon’s existence. A central goal of physics is to understand why different materials exhibit specific properties, such as electrical, optical, thermal, or magnetic behavior. These [...]
