A continuum approximation for the excitations of the (1,1,...,1) interface in the quantum Heisenberg model
It is shown that, with an appropriate scaling, the energy of low-lying excitations of the (1, 1,...,1) interface in the d-dimensional quantum Heisenberg model are given by the spectrum of the (d-1)-dimensional Laplacian on a suitable domain.
