Validity of the spin-wave approximation for the free energy of the Heisenberg ferromagnet
Michele Correggi, Alessandro Giuliani, Robert Seiringer
We consider the quantum ferromagnetic Heisenberg model in three dimensions, for all spins . We rigorously prove the validity of the spin-wave approximation for the excit…

On the Ginzburg--Landau Functional in the Surface Superconductivity Regime
M. Correggi, N. Rougerie
We present new estimates on the two-dimensional Ginzburg-Landau energy of a type-II superconductor in an applied magnetic field varying between the second and third critical fields…
