The Quantum Hall Effect: Novel Excitations and Broken Symmetries
by Steven M. Girvin
Publisher: arXiv 1999
Number of pages: 124
These pedagogical lecture notes present a general introduction to most aspects of the integer and fractional quantum Hall effects. This is followed by an extensive discussion of quantum Hall ferromagnetism, both for spins in single-layer systems and "pseudospins" in double-layer systems. The effective field theories describing various broken symmetry states and "skyrmion" and "meron" spin textures are derived and discussed in some detail.
