New Analysis Suggests That A Neutrino Laser Is Unattainable

As cool as it will have been to wield lasers that produce a beam of neutrinos, lately two papers have been revealed by MIT researchers that appear to dampen the likelihood of such lasers being in any respect attainable. In a review paper by [Ana Maria Rey] et al. these two papers are investigated in additional element.

Although the idea behind a neutrino laser is quite easy, utilizing the identical superradiance impact involving a Bose-Einstein condensate (BEC) that permits for stimulation by photons to lead to a synchronized course of emitted photons, the thought of utilizing a BEC of radioisotopes that naturally emit neutrinos on this vogue has now been successfully shot down.

The drawback lies in taking the leap from photons with a BEC and making use of this to a BEC of radioisotopes. Whereas photons are comparatively gradual and low-energy at a mere 1 eV, a neutrino is extraordinarily quick and at 1+ MeV correspondingly has a a lot better kinetic impact on the particle that emitted it. Unlike a photon emitted by an atom, this leaves valuable little time for the opposite particles within the BEC to be affected.

This first situation is roofed in the (paywalled) paper by [Yu-Kun Lu] et al. with their calculations exhibiting that superradiance can’t happen with neutrinos in a BEC and thus a laser is inconceivable. In the (additionally paywalled) second paper by [Hanzhen Lin] et al. the query is requested whether or not the idea {that a} BEC of a radioisotope will in any respect improve radioactive decay, to which the reply is a curt ‘no’.

Although it’s inconceivable to show a adverse with the scientific methodology, these two research have slammed shut a few doorways on the idea of a neutrino laser.
