Stripe-tetragonal first order phase transition in ultra-thin magnetic films
Sergio A. Cannas, Daniel A. Stariolo, Francisco A. Tamarit
We analyze the nature of the phase transition from a smectic stripe phase to a tetragonal phase predicted in analytic studies by Abanov et al. (Phys. Rev. B 51, 1023 (1995)) and ob…
Testing boundary conditions efficiency in simulations of long-range interacting magnetic models
Sergio A. Cannas, Cintia M. Lapilli, Daniel A. Stariolo
Periodic boundary conditions have not a unique implementation in magnetic systems where all spins interact with each other through a power law decaying interaction of the form $1/r…
Non glassy ground-state in a long-range antiferromagnetic frustrated model in the hypercubic cell
Leonardo Franco, Sergio A. Cannas
We analize the statistical mechanics of a long-range antiferromagnetic model defined on a D-dimensional hypercube, both at zero and finite temperatures. The associated Hamiltonian…
