 \section{Introduction}
 
+In the previous chapter we have introduced a theoretical framework
+which will allow us to study measurement backaction using
+discontinuous quantum jumps and non-Hermitian evolution due to null
+outcomes. We have also wrapped our quantum gas model in this quantum
+trajectory formalism by considering ultracold bosons in an optical
+lattice coupled to a cavity which collects and enhances light
+scattered in one particular direction. One of the most important
+conclusions of the previous chapter was that the introduction of
+measurement introduces a new energy and time scale into the picture.
+
+In this chapter, we investigate the effect of quantum measurement
+backaction on the many-body state of atoms.
