Stacked triangular XY antiferromagnets: End of a controversial issue on the phase transition

In this paper, we show, by using the Wang–Landau flat-histogram Monte Carlo method, that the phase transition in the XY stacked triangular antiferromagnet is clearly of first order, confirming results from latest Monte Carlo simulation and from a nonperturbative renormalization group, putting an end...

Zusammenfassung:In this paper, we show, by using the Wang–Landau flat-histogram Monte Carlo method, that the phase transition in the XY stacked triangular antiferromagnet is clearly of first order, confirming results from latest Monte Carlo simulation and from a nonperturbative renormalization group, putting an end to a long-standing controversial issue.
