Winding Number - Winding Number and Heisenberg Ferromagnet Equations

Winding Number and Heisenberg Ferromagnet Equations

Finally, note that the winding number is closely related with the (2 + 1)-dimensional continuous Heisenberg ferromagnet equations and its integrable extensions: the Ishimori equation etc. Solutions of the last equations are classified by the winding number or topological charge (topological invariant and/or topological quantum number).

Famous quotes containing the words winding and/or number:

    He’s winding up the watch of his wit. By and by it will strike.
    William Shakespeare (1564–1616)

    Of all reformers Mr. Sentiment is the most powerful. It is incredible the number of evil practices he has put down: it is to be feared he will soon lack subjects, and that when he has made the working classes comfortable, and got bitter beer into proper-sized pint bottles, there will be nothing left for him to do.
    Anthony Trollope (1815–1882)
