I will describe our recent work on the nondestructive imaging of ultracold lattice gases. By the simultaneous use of sideband cooling, we show that fluorescence images of the lattice gas can be obtained while retaining the atoms in the ground vibrational band. By extending this technique to very low lattice depths with correspondingly large quantum tunneling rates, we also show that the act of observation, i.e. imaging, causes the suppression of tunneling - a manifestation of the quantum Zeno effect. I will discuss applications of such measurement-induced control of lattice gases for cooling, control and state preparation.
