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…
Suppression and enhancement of bosonic stimulation by atomic interactions
Konstantinos Konstantinou, Yansheng Zhang, Paul H. C. Wong +7
The tendency of identical bosons to bunch, seen in the Hanbury Brown-Twiss effect and Bose-Einstein condensation, is a hallmark of quantum statistics. This bunching can enhance the…
Probing quantum many-body dynamics using subsystem Loschmidt echos
Simon Karch, Souvik Bandyopadhyay, Zheng-Hang Sun +9
The Loschmidt echo - the probability of a quantum many-body system to return to its initial state following a dynamical evolution - generally contains key information about a quant…
In situ imaging of the thermal de Broglie wavelength in an ultracold Bose gas
Jinggang Xiang, Enid Cruz-Colón, Candice C. Chua +4
We report the first in situ observation of density fluctuations on the scale of the thermal de Broglie wavelength in an ultracold gas of bosons. Bunching of Rb atoms in a qu…
