Use of Interaction Picture
The purpose of the interaction picture is to shunt all the time dependence due to H0 onto the operators, leaving only H1, I affecting the time-dependence of the state vectors.
The interaction picture is convenient when considering the effect of a small interaction term, H1, S, being added to the Hamiltonian of a solved system, H0, S. By switching into the interaction picture, you can use time-dependent perturbation theory to find the effect of H1, I.

Famous quotes containing the words interaction and/or picture:
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
“A picture is a fact.”
—Ludwig Wittgenstein (1889–1951)
