    "abstract": "Studies of ultracold atoms in optical lattices link various disciplines,\nproviding a playground where fundamental quantum many-body concepts, formulated\nin condensed-matter physics, can be tested in much better controllable atomic\nsystems, e.g., strongly correlated phases, quantum information processing.\nStandard methods to measure quantum properties of Bose-Einstein condensates\n(BECs) are based on matter-wave interference between atoms released from traps\nwhich destroys the system. Here we propose a nondestructive method based on\noptical measurements, and prove that atomic statistics can be mapped on\ntransmission spectra of a high-Q cavity. This can be extremely useful for\nstudying phase transitions between Mott insulator and superfluid states, since\nvarious phases show qualitatively distinct light scattering. Joining the\nparadigms of cavity quantum electrodynamics (QED) and ultracold gases will\nenable conceptually new investigations of both light and matter at ultimate\nquantum levels, which only recently became experimentally possible. Here we\npredict effects accessible in such novel setups.",
