Summary
Project 4 focuses on the electronic properties of oxide superconductors and related materials, and the microscopic origin of superconductivity and other states of matter which they present. An important aspect of this program is the exploration of new routes towards novel superconducting materials. One part of this effort rests on extending known classes of materials, including high-Tc cuprates, by means of chemical substitution, while another will be the exploration of completely different directions in materials research. The program focuses on the investigation of the physical properties of the various states of matter, such as those containing resonating valence bonds, magnetism, orbital currents and density waves, and superconductivity. These will be studied at different conditions of stoichiometry, pressure, carrier density, magnetic field, and temperature. The aim of the experiments is to gain a deeper understanding of the competition between the superconducting phase and the other possible states of matter. The experiments will be complemented by numerical simulations based on modern computational techniques such as dynamical mean field theory. More importantly, to make real progress in this field novel and theoretical ideas are crucial. The emphasis of the theoretical efforts within this program is for this reason on original and qualitatively new approaches to physics of strongly correlated matter.
