It Takes More than Moore to Answer Existence-Questions

© 2019 Springer Nature. This is a post-peer-review, pre-copyedit version of an article published in Erkenntnis. The final authenticated version is available online at: https://doi.org/10.1007/s10670-019-00107-4Several recent discussions of metaphysics disavow existence-questions, claiming that they are metaphysically uninteresting because trivially settled in the affirmative by Moorean facts. This is often given as a reason to focus metaphysical debate instead on questions of grounding. I argue that the strategy employed to undermine existence-questions fails against its usual target: Quineanism. The Quinean can protest that the formulation given of their position is a straw man: properly understood, as a project of explication, Quinean metaphysics does not counsel us to choose between obvious ordinary-language claims and absurd revisionist claims, even if appeal to Moorean facts is permitted.Peer reviewedFinal Accepted Versio

Edge Mode Combinations in the Entanglement Spectra of Non-Abelian Fractional Quantum Hall States on the Torus

We present a detailed analysis of bi-partite entanglement in the non-Abelian Moore-Read fractional quantum Hall state of bosons and fermions on the torus. In particular, we show that the entanglement spectra can be decomposed into intricate combinations of different sectors of the conformal field theory describing the edge physics, and that the edge level counting and tower structure can be microscopically understood by considering the vicinity of the thin-torus limit. We also find that the boundary entropy density of the Moore-Read state is markedly higher than in the Laughlin states investigated so far. Despite the torus geometry being somewhat more involved than in the sphere geometry, our analysis and insights may prove useful when adopting entanglement probes to other systems that are more easily studied with periodic boundary conditions, such as fractional Chern insulators and lattice problems in general.Comment: 13 pages, 8 figures, published version on PR

Wanted More from Moore

I was very excited when I first picked up Wes Moore’s book The Other Wes Moore. After hearing that it was chosen as the common reading text for the incoming class, and also being given the opportunity to co-facilitate a discussion based on the book, I was even more excited. However, as I read the book, I found myself more frustrated than fulfilled. [excerpt

MICROELECTRONIC RELIABILITY MODELS FOR MORE THAN MOORE NANOTECHNOLOGY PRODUCTS

Disruptive technologies face a lack of Reliability Engineering Standards and Physics of Failure (PoF) heritage. Devices based on GaN, SiC, Optoelectronics or Deep-Submicron nanotechnologies or 3D packaging techniques for example are suffering a vital absence of screening methods, qualification and reliability standards when anticipated to be used in Hi-Rel application. To prepare the HiRel industry for just-in-time COTS, reliability engineers must define proper and improved models to guarantee infant mortality free, long term robust equipment that is capable of surviving harsh environments without failure. Furthermore, time-to-market constraints require the shortest possible time for qualification. Breakthroughs technologies are generally industrialized for short life consumer application (typically smartphone or new PCs with less than 3 years lifecycle). How shall we qualify these innovative technologies in long term Hi-Rel equipment operation? More Than Moore law is the paradigm of updating what are now obsolete, inadequate screening methods and reliability models and Standards to meet these demands. A State of the Art overview on Quality Assurance, Reliability Standards and Test Methods is presented in order to question how they must be adapted, harmonized and rearranged. Here, we quantify failure rate models formulated for multiple loads and incorporating multiple failure mechanisms to disentangle existing reliability models to fit the 4.0 industry needs

The Anatomy of an International Fashion Retailer – The Giorgio Armani Group

Of all the international retailers, luxury fashion retailers are typically the most prolific as measured by the number and diversity of foreign markets in which they operate. Furthermore, for most, the contribution of foreign sales to total sales is equal to, if not greater than, that achieved by the most active international retailers (Moore & Fernie 2004). Yet, while the significance of the luxury fashion retailers’ foreign activities is now acknowledged in the international retailing literature, there have been calls for more in-depth, company specific appraisals of the strategies adopted by such firms (Doherty 2000; Moore, Birtwistle & Burt 2004). Doherty (2000) has argued in particular that further case study research in the area of fashion retailer internationalisation would provide much needed insights into the apparatus that supports their international success
