Ferrier-Barbut replies: I am grateful for Aurel Bulgac’s insight about three-body stabilized quantum droplets. I was aware of his work, but space constraints made it impossible for me to cite the broad swath of related literature. A tritium droplet would certainly be a peculiar object, though as an experimentalist I think making a Bose–Einstein condensate of tritium would be quite challenging.
