Research Interests
Fisher's research has focussed on exotic phenomena in strongly interacting many-body quantum systems, especially electrons and spins in crystalline solids. Examples include the fractional quantum Hall effect, high temperature superconductors, topologically ordered phases and onedimensional quantum wires, wherein electron interactions can lead to the emergence of quasiparticle excitations with fractional charge and statistics. This phenomena is of relevance to a possible futuristic topological quantum computer. He has also been interested in novel quantum phases and phase transitions with gapless strongly interacting quantum fluctuations which can reflect the emergence of Dirac Fermions and gauge fields, formerly the staple of particle physics.
