Inherent Structure Entropy of Supercooled Liquids

Abstract: We present a quantitative description of the thermodynamics in a supercooled binary Lennard-Jones liquid via the evaluation of the degeneracy of the inherent structures, i.e., of the number of potential energy basins in configuration space. We find that the contribution of the inherent structures to the free energy of the liquid almost completely decouples from the vibrational contribution. An important by-product of the presented analysis is the determination of the Kauzmann temperature for the studied system.

The origin of high critical currents in YBa2Cu3O7-d thin films

Abstract: Thin films of the high-temperature superconductor YBa2Cu3O7−δ exhibit both a large critical current (the superconducting current density generally lies between 1011 and 1012 A m−2 at 4.2 K in zero magnetic field) and a decrease in such currents with magnetic field that point to the importance of strong vortex pinning along extended defects1,2. But it has hitherto been unclear which types of defect—dislocations, grain boundaries, surface corrugations and anti-phase boundaries—are responsible. Here we make use of a sequential etching technique to address this question. We find that both edge and screw dislocations, which can be mapped quantitatively by this technique, are the linear defects that provide the strong pinning centres responsible for the high critical currents observed in these thin films. Moreover, we find that the superconducting current density is essentially independent of the density of linear defects at low magnetic fields. These natural linear defects, in contrast to artificially generated columnar defects, exhibit self-organized short-range order, suggesting that YBa2Cu3O7−δ thin films offer an attractive system for investigating the properties of vortex matter in a superconductor with a tailored defect structure.

Gaining competitive advantage through customer value oriented management

Abstract: Within the customer value literature there is a lacuna of theoretical frameworks and models that underlie consumers’ overall product valuation. This paper addresses this limitation and presents a model integrating consumer values, product benefits, and various costs of consumption. In the proposed model, benefits and costs are defined in terms of consumers’ perceptions in the activities of acquisition, consumption, and maintenance, as well as consumers’ expectation of value satisfaction before buying.
