Dynamics and thermodynamics of rotators interacting with both long and short range couplings
Alessandro Campa, Andrea Giansanti, David Mukamel +1
The effect of nearest-neighbor coupling on the thermodynamic and dynamical properties of the ferromagnetic Hamiltonian Mean Field model (HMF) is studied. For a range of antiferroma…

Microcanonical solution of the mean-field model: comparison with time averages at finite size
Alessandro Campa, Stefano Ruffo
We solve the mean-field model in an external magnetic field in the microcanonical ensemble using two different methods. The first one is based on Rugh's microcanonical formal…
