Abstract
We explain qualitatively why the staggered flux state plays a central role in the SU(2) formulation of the t-J model, which we use to model the pseudogap state in underdoped cuprates. This point of view is supported by studies of projected wavefunctions. In addition to staggered orbital current correlations, we present here for the first time results of correlations involving hole and spin chirality and show that the two are closely related. The staggered flux state allows us to construct cheap and fast vortices, which may hold the key to explaining the many anomalous properties of the normal state.
