Michael Ruggenthaler, Johannes Flick, Camilla Pellegrini, Heiko Appel, I. V. Tokatly, Ángel Rubio · Physical Review A · 2014
A comprehensive derivation of a feasible method that generalizes ideas of the time-dependent density-functional theory is presented, thereby providing a scheme to perform $a\phantom{\rule{0}{0ex}}b$ $i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}o$ calculations of quantum particles coupled to photons.
