Can Bose-Einstein condensates enhance radioactive decay?
Hanzhen Lin, Yukun Lu, Wolfgang Ketterle
This paper 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 $\a…
Fringe visibility and which-way information in Young's double slit experiments with light scattered from single atoms
Hanzhen Lin, Yu-Kun Lu, Vitaly Fedoseev +3
Young's double slit experiment has often been used to illustrate the concept of complementarity in quantum mechanics. If information can in principle be obtained about the path of…
Fundamental impossibility of a superradiant neutrino laser
Yu-Kun Lu, Hanzhen Lin, Wolfgang Ketterle
Here we address the fundamental question of whether an idealized system of atoms will show collective behavior and superradiance when it emits fermions instead of photons. We s…
Comment on "Possibility of superradiant neutrino emission by atomic condensate" by M. Blasone, L. Gastaldo and F. Romeo, Phys. Rev. D 113, 053010 (2026)
Wolfgang Ketterle, Hanzhen Lin, Yu-Kun Lu
We show that the recent proposal for superradiant emission of neutrinos cannot evade our proof that superradiant neutrino emission is fundamentally impossible. Pairing two fermions…
Coherent and incoherent light scattering by single-atom wavepackets
Vitaly Fedoseev, Hanzhen Lin, Yu-Kun Lu +3
We study light scattering of single atoms in free space and discuss the results in terms of atom-photon entanglement and which-way information. Using ultracold atoms released from…
