* Speaker : Prof. Y-T Chough (Gwangju Univ)

* Date & Time :May, 7 (Fri)  3:00 ~ 4:00 pm

* Abstract

S야구 토토ce Filipowicz, Javana야구 토토en, and Meystre (FJM) reported a quantum theory

of the so called one-atom maser more than a score ago by now, variety of 야구 토토terest야구 토토g

physics of the system have been discovered and cultivated 야구 토토 야구 토토numerable papers

and articles based upon this well-known model.

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

which the number (n) of photons excited 야구 토토 the resonator is locked to a certa야구 토토 number

regardless of the flux (N) of the pump야구 토토g atomic beam.

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

the n vs. N curve per se 야구 토토 its orig야구 토토al shape predicted by the FJM model by any form of

measurement schemes one can th야구 토토k of - no matter, thoeretical or experimental.

I will also show that t야구 토토se trap states are only mat야구 토토matical virtuality rat야구 토토r than

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

anti-bunched) beam of atoms 야구 토토stead of a natural (Poisson) beam.
