标题time dependent perturbation
时间Tue Jan 8 02:30:21 2008
consider the 1D quantum system with hamiltonian H0. Let H'(x,t)=H'(x) exp(iwt)
+[H'(x)]* exp(-iwt) be a time dep perturbation suppose H0 describes an
infinite potential and H'(x)=-eEx due to an oscillatory electrical field.
Show that the transition is allowed only between two states with opposite
parity.
With s.o interaction, the Hamiltonian operator is H=H0+cL(dot)S.Let J=L+S
be the total angular momentum operator.
write the largest set of commuting operators(including H)
知道的人拜托教一下小弟吧 谢谢
