Two-fluid behavior of the Kondo lattice in the 1/N slave boson approach

It has been recently shown by Nakatsuji, Pines, and Fisk [S. Nakatsuji, D. Pines, and Z. Fisk, Phys. Rev. Lett. 92, 016401 (2004)] from the phenomenological analysis of experiments in Ce1-xLaxCoIn5 and CeIrIn5 that thermodynamic and transport properties of Kondo lattices below coherence temperature can be very successfully described in terms of a two-fluid model, with Kondo impurity and heavy electron Fermi liquid contributions. We analyze thermodynamic properties of Kondo lattices using 1/N slave boson treatment of the periodic Anderson model and show that these two contributions indeed arise below the coherence temperature. We find that the Kondo impurity contribution to thermodynamics corresponds to thermal excitations into the flat portion of the energy spectrum.Comment: 7 pages, 2 figure

Credit Where It’s Due: The Law and Norms of Attribution

The reputation we develop by receiving credit for the work we do proves to the world the nature of our human capital. If professional reputation were property, it would be the most valuable property that most people own because much human capital is difficult to measure. Although attribution is ubiquitous and important, it is largely unregulated by law. In the absence of law, economic sectors that value attribution have devised non-property regimes founded on social norms to acknowledge and reward employee effort and to attribute responsibility for the success or failure of products and projects. Extant contract-based and norms-based attribution regimes fail optimally to protect attribution interests. This article proposes a new approach to employment contracts designed to shore up the desirable characteristics of existing norms-based attribution systems while allowing legal intervention in cases of market failure. The right to public attribution would be waivable upon proof of a procedurally fair negotiation. The right to attribution necessary to build human capital, however, would be inalienable. Unlike an intellectual property right, attribution rights would not be enforced by restricting access to the misattributed work itself; the only remedy would be for the lost value of human capital. The variation in attribution norms that currently exists in different workplace cultures can and should be preserved through the proposed contract approach. The proposal strikes an appropriate balance between expansive and narrow legal protections for workplace knowledge and, in that respect, addresses one of the most vexing current debates at the intersection of intellectual property and employment law
