Dyson time velocity operation

Wiki Markup
Show that exp(-i(A+B))t \!= exp(-iAt)exp(-iBt) unless \[A,B\]=0.


It is equal to exp(-iAt)T exp(-i integrate\[B'(t)\]dt) ; B'=exp(iAt)B exp(-iAt), T is Dyson time velocity operator.

  • Show that H~(1) = 0 => if symmetric sequence H~(odd) = 0
  • Show that H~(0)finite pulse != 0, but equal to w1/wD
