Non-perturbative effective field theory for two-leg antiferromagnetic spin ladders
D. C. Cabra, A. Dobry, G. L. Rossini
We study the long wavelength limit of a spin 1/2 Heisenberg antiferromagnetic two-leg ladder, treating the interchain coupling in a non-perturbative way. We perform a mean field an…

Mixing of magnetic and phononic excitations in incommensurate Spin-Peierls systems
Ariel Dobry, David Ibaceta
We analyze the excitation spectra of a spin-phonon coupled chain in the presence of a soliton. This is taken as a microscopic model of a Spin-Peierls material placed in a high magn…

Montecarlo simulation of the role of defects as the melting mechanism
Liliana Gomez, Ariel Dobry, Hung Diep
We study in this paper the melting transition of a crystal of fcc structure with the Lennard-Jones potential, by using isobaric-isothermal Monte Carlo simulations. Local and collec…
