Insight into entropy
TLDR
In this article, the qualitative character of entropy has been investigated and several examples from statistical mechanics (including liquid crystal reentrant phases, two different lattice gas models, and the game of poker) demonstrate facets of this difficult question and point toward an answer.Abstract:
What is the qualitative character of entropy? Several examples from statistical mechanics (including liquid crystal reentrant phases, two different lattice gas models, and the game of poker) demonstrate facets of this difficult question and point toward an answer. The common answer of “entropy as disorder” is regarded here as inadequate. An alternative but equally problematic analogy is “entropy as freedom.” Neither simile is perfect, but if both are used cautiously and not too literally, then the combination provides considerable insight.read more

Tailoring the Morphology of LiCoO2: A First Principles Study
Denis Kramer,Gerbrand Ceder +1 more
TL;DR: In this paper, the surface energies of several low-index surfaces of layered LiCoO2 are investigated as a function of the external lithium and oxygen chemical potentials by means of First Principles calculations in the generalized gradient approximation (GGA) to density functional theory.
Journal ArticleDOI
Statistical mechanics of glass
TL;DR: In this paper, the authors provide an overview of various statistical mechanical descriptions of the glassy state and their practical use in understanding glass physics and in the design of new glass compositions.

Cortical entropy changes with general anaesthesia: theory and experiment.
TL;DR: It is concluded that spectral entropy may be a sensitive monitor of the consciousness-unconsciousness transition, rather than a progressive indicator of anaesthetic drug effect.

Evolution in thermodynamics
TL;DR: A review of evolution in thermodynamics can be found in this article, where two aspects of "evolution" are discussed: the first is that thermodynamics is becoming the domain of physics that accounts for evolution in nature, in general, and the second is that science is the evolving add-on that empowers humans to predict the future and move more easily on earth, farther and longer in time.
Journal ArticleDOI
Development and assessment of research-based tutorials on heat engines and the second law of thermodynamics
TL;DR: In this paper, student ability to apply the second law of thermodynamics to cyclic devices such as heat engines and refrigerators was investigated and two tutorials were developed to supplement instruction in standard undergraduate courses.

Magnetic relaxation in high-temperature superconductors
TL;DR: In this article, experimental studies of the time decay of the nonequilibrium magnetization in high-temperature superconductors, a phenomenon known as magnetic relaxation, are reviewed from a purely experimental perspective and discussed in the context of present phenomenological theories.
Journal ArticleDOI
Phase transitions in liquid crystals
TL;DR: A comprehensive overview of phase transition studies can be found in this article, where the authors identify the essential key concepts and points of difficulty associated with the study of phase transitions and discuss the most widely used experimental techniques for measuring these transition properties.

The structure of a new phase of ice
TL;DR: A new, twelfth phase of crystalline ice has been identified in this paper, with a density similar to that of iceIV, which also occurs in this pressure range within the stability region of ice V. This region of the water phase diagram thus provides a potential model system forexperimental and theoretical studies ofmetastability.

Hard‐Sphere Lattice Gases. I. Plane‐Square Lattice
David S. Gaunt,Michael E. Fisher +1 more
TL;DR: In this paper, a plane square lattice gas of hard square which exclude the occupation of nearest neighbor sites is studied by deriving 13 terms of the activity and the virial series and nine terms of appropriate high density expansions.

Hard-square lattice gas
TL;DR: In this article, the first 24 terms of the high-density series for the order parameterρ2−ρ1 were obtained from corner transfer matrices, and from these they estimate the critical activity to be 3.7962±0.0001.
