Hi all,
While I am reading interaction of atoms with radiation the following doubt came to me...While solving Maxwell equations in a charge and current free region, we get solutions for Vector potential,Electric field and so on which are plane wave solutions...However, when we study the interaction of these fields with say Hydrogen atom/any charged particle, to compute the interaction Hamiltonian we still use the same potential as before...My doubt is that when we placed an charged particle, the space is no more a charge free region..How can we still use the same old solutions of Maxwell equations for potential and carry out the computations..Am I missing any crucial point..?.Please help me in solving this doubt..
