Quantum Hall Effect: Fractional Research Jonathan Nothen French edition

The main focus of the paper is the Chern-Simons-Ginzburg-Landau theory. This book shows that even if one believes that one has a good understanding of a phenomenon, it is not always correct. And there is another morale to the story as well: Although this construction at the time of discovery seemed to have no application, it was still convenient to explain an actual physical phenomenon. In other words, a theoretical construction might be useful in the future even though it does not seem so at the moment.
