Alan interested in the discovery of superconductivity at liquid nitrogen temperatures in the cuprate superconductors has stimulated tremendous interest in the magnetic properties of these materials. Understanding these properties poses a considerable theoretical challenge, as we are confronted with the competing effects of thermal fluctuations, material anisotropy, and disorder; the manner in which this competition is resolved is a central theme in contemporary condensed matter physics. These are precisely the issues which are being addressed by Alan Dorsey's research on the transport properties of the vortex phase in the cuprate superconductors. His research has unveiled interesting scaling properties of transport coefficients such as the electrical conductivity; these scaling theories are now commonly used by experimentalists to analyze the phase transitions which occur between different vortex phases (the vortex liquid to vortex glass transition, for instance). More recently he has been interested in the pseudogap regime of the underdoped cuprates, and has developed a theory of the effect of fluctuations of the phase of the order parameter on the quasiparticle properties.
