Query: Stability of the skyrmion lattice near the critical temperature in cubic
  helimagnets   The phase diagram of cubic helimagnets near the critical temperature is
obtained from a Landau-Ginzburg model, including fluctuations to gaussian
level. The free energy is evaluated via a saddle point expansion around the
local minima of the Landau-Ginzburg functional. The local minima are computed
by solving the Euler-Lagrange equations with appropriate boundary conditions,
preserving manifestly the full nonlinearity that is characteristic of skyrmion
states. It is shown that the fluctuations stabilize the skyrmion lattice in a
region of the phase diagram close to the critical temperature, where it becomes
the equilibrium state. A comparison of this approach with previous computations
performed with a different approach (truncated Fourier expansion of magnetic
states) is given.
