Having remembered an article about superabsorption increasing battery charge rate, I wondered whether there is superradiance with electrons, and there is! : "Superradiance and Subradiance due to Quantum Interference of Entangled Free Electrons" (2021) https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.127.060403 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.12... > [...] Our findings suggest that light emission can be sensitive to the explicit quantum state of the emitting matter wave and possibly serve as a nondestructive measurement scheme for measuring the quantum state of many-body systems.
