Specific Heat Anomaly in a Supercooled Liquid with Amorphous Boundary Conditions
(American Physical Society, 2015-06)
We study the specific heat of a model supercooled liquid confined in a spherical cavity with amorphous boundary conditions. We find the equilibrium specic heat has a cavity-size-dependent peak as a function of temperature. ...
Determining the heterogeneity in time of the dynamics within a slowly relaxing region of a supercooled liquid: Role of sharp relaxation events
(American Physical Society, 2009-08-26)
Supercooled liquids have been shown to be dynamically heterogeneous with different regions of the system presenting dynamics that vary from each other even by orders of magnitude. Computer simulations have confirmed such ...
Identifying a causal link between structure and dynamics in supercooled water
(Europhysics Letters, 2009-10)
By means of molecular-dynamics simulations we firmly establish the long-awaited existence of strong correlations between structure and dynamics for a glass-forming system: supercooled water. We find molecules with similar ...
Elemental and cooperative diffusion in a liquid, supercooled liquid and glass resolved
(American Institute of Physics, 2017-07-01)
Intermolecular vibrations and fast relaxations in supercooled ionic liquids
(AMER INST PHYSICS, 2011)
Short-time dynamics of ionic liquids has been investigated by low-frequency Raman spectroscopy (4 < omega < 100 cm(-1)) within the supercooled liquid range. Raman spectra are reported for ionic liquids with the same anion, ...
Temperature anomalies of hypersound velocity and specific heat ratio in liquid Quinoline
(ELSEVIER SCIENCE, 2005-08-15)
Results of an extensive study of dynamic polarized (VV) and depolarized (VH) Rayleigh-Brillouin light scattering in Quinoline as a function of temperature are presented. The VV spectrum is analyzed by taking into account ...
Study on transient ice formation of laminar flow inside externally supercooled rectangular duct
(2000-12-01)
The transient process of solidification of laminar liquid flow (water) submitted to super-cooling was investigated both theoretically and experimentally. In this study an alternative analytical formulation and numerical ...
Size dependence of dynamic fluctuations in liquid and supercooled water
(American Institute of Physics, 2019-04)
We study the evolution of dynamic fluctuations averaged over different space lengths and time scales to characterize spatially and temporally heterogeneous behavior of TIP4P/2005 water in liquid and supercooled states. ...
Enhanced Gruneisen Parameter in Supercooled Water
(Nature Publishing Group, 2019-08-19)
We use the recently-proposed compressible cell Ising-like model to estimate the ratio between thermal expansivity and specific heat (the Gruneisen parameter Gamma(s)) in supercooled water. Near the critical pressure and ...
