Topological Coherence and Decoherence
... We are interested in topological field theories because they possess ‘hidden’ topological quantum numbers which are conserved even when the system is subject to quite severe perturbations. A model of central interest is the ‘dissipative W.A.H. model’ (named after Wannier, Az’bel, & Hofstadter’). Thi ...

... A.3 Perturbation theory and the Second Golden Rule In perturbation theory the Hamiltonian at any time t may be written as H(t)=H0+V(t), where H0 is unperturbed Hamiltonian and V(t) is small. The solution for eigenfunctions of H starts by expanding in the terms of the complete set of energy eigenfun ...

This gives us classical expressions for the density of the conserved quantity, the current density for this, and (by integrating the density over all space) th ...

7. Laplace equation...the basis of potential theory
... Laplace's equation is the classic example of an elliptic PDE. This means that it has no characteristics, and one typically encounters the problem of satisfying (1) in the interior of a domain subject to one boundary condition at each point along the boundary. If the boundary data are function values ...
