The overlap parameter across an inverse first-order phase transition in a 3D spin-glass

We investigate the thermodynamic phase transition taking place in the Blume-Capel model in the presence of quenched disorder in three dimensions. In particular, performing exchange Monte Carlo simulations, we study the behaviour of the order parameters across the first-order phase transition and its...

Description
Summary:We investigate the thermodynamic phase transition taking place in the Blume-Capel model in the presence of quenched disorder in three dimensions. In particular, performing exchange Monte Carlo simulations, we study the behaviour of the order parameters across the first-order phase transition and its related coexistence region. This transition is inverse freezing.
