[問題] 量子力學-harmonic oscillator問題
A charged harmonic oscillator of mass m=1 and charge q=1 is oscillating
under the influence of a spring with natural frequency ω'=(k/m)^(1/2) ,
where k=1 is the force constant ,and is found in the ground state. If
suddenly an external electrical field E=1 is turned on such that the total
potential of system becomes (1/2)m(ω'x)^2 -qEx
(a) Show that by change of variable the system equivalent to another harmonic
oscillator. what is the new frequency ω?
(b) what is the probability of finding the system in the ground state and
first excited state of the system after the E-field is turned on?
