Srednicki equation 5.10

  • #1

Main Question or Discussion Point

In equation 5.10, second line srednicki uses the same definition as eq 5.6, while 5.6 is time independent [tex]a_1^{\dagger}(k)[/tex] and in 5.10 we have to use the new time dependent [tex]a_1^{\dagger}(t)[/tex] . Why dont we have a new [tex]a_1^{\dagger}(t)[/tex], which say explicitly depends on t ?

I will be glad if someone can explain :)

just before eq 5-8:

One complication is that a†(k) will no longer be time independent, and so a†1, eq. (5.6),
becomes time dependent as well.

It will be very kind if you can also explain how to understand paragraph starting with "We would like ........ is not zero" on page 39, after equation 5.17
