The primary goal of Professor Kakalios’ research is the elucidation of the properties of disordered systems. Experimental investigations include studies of the electronic and optical properties of amorphous semiconductors, segregation phenomena in granular media, and fluctuation phenomena in neurological systems.

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.
