Probing the quantum state of a 1D Bose gas using off-resonant light scattering

Andrew Sykes
T-4 and CNLS

The remarkable progress made in cold atom physics over the past two decades has been facilitated by the precision and flexibility of the measurement tools available to experimentalists. Optical probing by lasers has proved to be one of the most important tools, for example absorption and phase contrast imaging have been extensively used to measure atomic density in boson and fermion systems. In this talk, I will present a theoretical treatment of coherent light scattering from an interacting 1D Bose gas at finite temperatures. I will show how this can provide a non-destructive measurement of the quantum state of the atomic system.
