Universal amplitude ratios in the 3D Ising Universality Class

Hasenbusch, Martin

Understand

We compute a number of universal amplitude ratios in the three-dimensional Ising universality class.

  • To this end, we perform Monte Carlo simulations of the improved Blume-Capel model on the simple cubic lattice.
  • For example, we obtain A_+/A_-=0.536(2) and C_+/C_-=4.713(7), where A_+- and C_+- are the amplitudes of the specific heat and the magnetic susceptibility, respectively.
  • The subscripts + and - indicate the high and the low temperature phase, respectively.
