SUMMARY

The discussion focuses on the relationship between Hamilton and momentum operators in quantum mechanics, specifically analyzing the equation iħ(∂/∂t + iΩ) = iħ(exp(-iΩt)(∂/∂t)exp(iΩt)). Participants clarify that the right-hand side resembles a unitary transformation of an operator. The equation is confirmed to relate to the momentum operator rather than the Hamiltonian operator, emphasizing the distinction between these two fundamental concepts in quantum mechanics.

why i[tex]\hbar[/tex]([tex]\partial[/tex]/[tex]\partial[/tex]t+i[tex]\Omega[/tex])=i[tex]\hbar[/tex]exp(-i[tex]\Omega[/tex]t)[tex]\partial[/tex]/[tex]\partial[/tex]texp(i[tex]\Omega[/tex]t)

In the RHS you have something that resembles the unitary trasformation of an operator. Where did you get the equation from ?
 
[tex]i\hbar(\frac{d}{dt}+ i\Omega) = i\hbar(exp(-i \Omega t) \frac{d}{dt} exp(i \Omega t)[/tex]

Well if exp(iOt) is your wavefunction, the RHS is just [tex]i\hbar(i \Omega )[/tex]

are you sure this equation is right? Looks like momentum operator, not hamilton.
