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:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“It’s no go the picture palace, it’s no go the stadium,
It’s no go the country cot with a pot of pink geraniums.
It’s no go the Government grants, it’s no go the elections,
Sit on your arse for fifty years and hang your hat on a pension.”
—Louis MacNeice (1907–1963)
