Enhanced Grüneisen Parameter in Supercooled Water

Abstract We use the recently-proposed compressible cell Ising-like model to estimate the ratio between thermal expansivity and specific heat (the Grüneisen parameter Γ s ) in supercooled water. Near the critical pressure and temperature, Γ s becomes significantly sensitive to thermal fluctuations of...
