This research establishes a fundamental quantum limit that definitively rules out the feasibility of 1 MeV neutrino lasers, confirming that coherent neutrino beams cannot be generated via superradiance in radioactive atom condensates. The study highlights how significant recoil effects and the fermionic nature of neutrinos prevent the necessary phase coherence for such a device to function.

Quantum physics limits rule out 1 MeV neutrino laser

Quantum ZeitgeistSeptember 2, 20264 min read

New research disproves the possibility of a neutrino laser, specifically a device operating around the 1 MeV range.

Researchers have demonstrated a fundamental limit to quantum physics, definitively ruling out the possibility of a laser emitting a beam of neutrinos. The work from Wolfgang Ketterle at MIT, along with postdocs Hanzhen Lin and Yu-Kun Lu, disproves a proposal centered around achieving laser-like beams by cooling radioactive atoms to nanokelvin temperatures. “These two papers are sort of punch one and punch two,” Ketterle says, explaining how the analysis, published in Physical Review Letters, establishes the impossibility of both neutrino and gamma-ray lasers due to recoil and…
