Can Bose-Einstein Condensates Enhance Radioactive Decay?
Phys. Rev. Lett. 137, 101805 – Published 2 September, 2026

Abstract
This Letter lays out the principles of how Bose-Einstein condensates can modify radioactive decay. We highlight the challenges of many modes and short coherence times due to the energies of the emitted radiation. Recent proposals for gamma-ray and neutrino lasers claim that using a Bose-Einstein condensate as a source would solve these issues. We show that this is not the case, and the proposed experiments would have a gain of only or smaller. We also analyze proposals for gamma-ray lasers based on stimulated annihilation of positronium Bose-Einstein condensates.

Note that a recent paper [14] claimed incorrectly that one-body decay is modified by a Luttinger liquid. The theoretical derivation uses an invalid long-wavelength approximation. It is not clear why the experimental results agree with the incorrect prediction. Our proof also rules out that there is bosonic enhancement of particle loss by optical pumping, as claimed in Ref. [15].

Note that recoil effects can be suppressed in a crystalline solid-state system with recoilless Mössbauer lines, where the emitters are tightly localized which is the limit opposite to the BEC case. Because of the Debye-Waller factor, the recoilless line has reasonable strength only for emissions up to 100 keV. It was used in the demonstration of x-ray Dicke superradiance [54]. Here, the multi-mode competition was avoided by exciting low-lying Dicke state directly with a coherent x-ray laser (and not by spontaneous emission from a fully inverted system, as discussed here) and operating at a Bragg angle.
