N2 - The variations in the sped of sound in a two-component Bose-Einstein condensate was analyzede. Two components of a Bose-Einstein condensate were coupled in the presence of an external field. Energy eigenstates were used to express the single-body Hamiltonian, which are the atomic dressed states of quantum optics. In two-component condensates where the dressed state energy splitting was much larger than the mean-field energies, atomic dressed states were used which diagonalize the single body Hamiltonian. Condensate collective properties depending on the strength of mean field interactions, like speed of the sound was controlled adiabatically by varing the dressed state angle.
