Light scattering for thermometry of fermionic atoms in an optical lattice
Physical Review Letters 103:17 (2009)
Abstract:
We propose a method of using off-resonant light scattering to measure the temperature of fermionic atoms tightly confined in a two-dimensional optical-lattice potential. We show that fluctuations of the intensity in the far-field diffraction pattern arising from thermal correlations of the atoms can be accurately detected above the shot noise by collecting photons scattered in a forward direction, with the diffraction maxima blocked. The sensitivity of this method of thermometry is enhanced by an additional harmonic trapping potential. © 2009 The American Physical Society.Light scattering for thermometry of fermionic atoms in an optical lattice.
