Paul Crowell and his research group focus on the transport of spin across interfaces between dissimilar materials as well as spin dynamics and relaxation in systems far from equilibrium. He is also interested in the excitations of inhomogeneous magnetic systems, particularly vortices. These experiments are carried out using transport and optical techniques developed in the Crowell group.
Physics of Matter
Condensed matter physics, and the closely associated discipline of
materials physics, are the largest subfields in physics. Condensed matter research at Minnesota spans a range that includes the strange properties of electricity at nanoscales, to activities that may truly be
considered "high science," understanding phenomena such as "superfluids," 3He and 4He.
Condensed matter and materials physics have been the
sources of numerous technologies important to daily life. These include
compound semiconductor electronics, magnetic and optical
storage systems, liquid crystal displays, and semiconductor lasers.
Among the many efforts at Minnesota aimed at future technology are the experiments in spintronics, which are attempting to solve problems associated with the coupling of a semiconductor and a ferromagnet. Several of the condensed matter faculty members participate in the Materials Research Science and Engineering Center, a collaborative effort by the University that crosses departmental boundaries.
The condensed matter group at Minnesota investigates a wide range of experimental and theoretical problems in superconductivity and superfluidity, magnetism, mesoscopic physics, liquid crystals, semiconductors, surface physics and complexity.
