Such a counter-intuitive possibility, e.g., a liquid that becomes unstable to gas-like fluctuations on cooling at positive pressure, has never been observed, neither in real substances nor in off-lattice simulations. More recently, such a reentrant scenario has been dismissed on the premise that the re-entrant spinodal would collide with the gas-liquid coexisting curve (binodal) in the pressure-temperature plane. Here we study, numerically and analytically, two previously introduced one-component patchy particle models that both show (i) a re-entrant limit of stability of the liquid phase and (ii) a re-entrant binodal, providing a neat in silico (and in charta) realization of such unconventional thermodynamic scenario.engjournal articlehttps://aip.scitation.org/doi/pdf/10.1063/1.4974830?class=pdfopen access544waterliquidsamorphous iceFísica (Física)Química física (Física)TermodinámicaQuímica22 Física2210 Química Física2213 Termodinámica23 Química
