    "abstract": "We study dressed Bose-Einstein condensates in an atom chip radio-frequency\ntrap. We show that in this system sufficiently strong dressing can be achieved\nto cause the widely used rotating wave approximation (RWA) to break down. We\npresent a full calculation of the atom - field coupling which shows that the\nnon-RWA contributions quantitatively alter the shape of the emerging dressed\nadiabatic potentials. The non-RWA contributions furthermore lead to additional\nallowed transitions between dressed levels. We use RF spectroscopy of\nBose-Einstein condensates trapped in the dressed state potentials to directly\nobserve the transition from the RWA to the beyond-RWA regime.",
