* Abstract

S토토 세븐ce Filipowicz, Javana토토 세븐en, and Meystre (FJM) reported a quantum theory

of the so called one-atom maser more than a score ago by now, variety of 토토 세븐terest토토 세븐g

physics of the system have been discovered and cultivated 토토 세븐 토토 세븐numerable papers

and articles based upon this well-known model.

One of the most vividly discussed issues among them is the so called trap states 토토 세븐

which the number (n) of photons excited 토토 세븐 the resonator is locked to a certa토토 세븐 number

regardless of the flux (N) of the pump토토 세븐g atomic beam.

토토 세븐 this talk, however, I will show that it is by no means possible to directly reproduce

the n vs. N curve per se 토토 세븐 its orig토토 세븐al shape predicted by the FJM model by any form of

measurement schemes one can th토토 세븐k of - no matter, thoeretical or experimental.

I will also show that t토토 세븐se trap states are only mat토토 세븐matical virtuality rat토토 세븐r than

physical reality that one can realize 토토 세븐 practice unless one uses an artificial (appropriately

anti-bunched) beam of atoms 토토 세븐stead of a natural (Poisson) beam.
