Abstract
The microscopic origin of the pseudogap state that exists in the underdoped cuprates remains unknown. The c-axis properties in the pseudogap regime are particularly anomalous. We use a recently proposed model of a d density wave that leads to staggered currents and the doubling of the unit cell to investigate the c-axis kinetic energy and the optical sum rule. The density of states expected in the model is also considered.
