    • Ensemble inequivalence in a mean-field XY model with ferromagnetic and nematic couplings 

      Pikovsky, Arkady; Gupta, Shamik; Teles, Tarcisio Nunes; Benetti, Fernanda Pereira da Cruz; Pakter, Renato; Levin, Yan; Ruffo, Stefano (2014) [Artigo de periódico]
      We explore ensemble inequivalence in long-range interacting systems by studying an XY model of classical spinswith ferromagnetic and nematic coupling.We demonstrate the inequivalence bymapping themicrocanonical phase diagram ...
