Query: Trapped Particles in $PT$ Symmetric Theories   $PT$ symmetric quantum mechanics for a particle trapped by the generalized
non-Hermitian harmonic oscillator potential is studied. It is shown that energy
and the expectation value of the position operator $x$ can not be real
simultaneously, if the particle is trapped. Non-vanishing boundary conditions
for the trapped particle in $PT$ symmetric theory are also discussed.
