Aqui jaz uma morte: atitudes fúnebres na trajetória da empresa funerária da família Haas de Blumenau
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2013.Desde os primeiros anos do século XX, a empresa da família Haas de Blumenau (Santa Catarina, Brasil) dedica-se ao mercado funerário. A pequena oficina, fundada por Mathias e seu pai, estabeleceu-se com a fabricação de túmulos e a arte dos marmoristas, com destaque para o próprio Mathias que esculpiu na pedra, túmulos e ornamentos funerários. A administração da empresa, sempre a cargo de membros da Haas, depois de algumas décadas de dedicação à arquitetura funerária e também civil, concentrou seus esforços na gerência de uma agência funerária. Com a funerária, a empresa ofereceu aos seus clientes uma série de serviços voltados ao cuidado do corpo e por último, entrou no segmento de vendas de planos funerários. Desde a sua fundação, a empresa enfrentou mudanças e teve que administrar momentos de transição e de adequação de seus produtos e investimentos para conciliar mudanças nos ritos e a entrada de novidades no mercado funerário. A trajetória da família Haas possibilitou as reflexões desta tese que buscou pensar sobre as atitudes fúnebres e a morte, em diferentes momentos, por meio de sua empresa. Contando com um acervo documental formado por imagens, escritos pessoais, partes de construções tumulares, blogs, notas fiscais, documentos administrativos, catálogos de modelos tumulares e depoimentos, foram percebidas mudanças no tratamento do corpo morto e no seu destino final. <br

The uniting of Europe and the foundation of EU studies: revisiting the neofunctionalism of Ernst B. Haas
No full textThis article suggests that the neofunctionalist theoretical legacy left by Ernst B. Haas is somewhat richer and more prescient than many contemporary discussants allow. The article develops an argument for routine and detailed re-reading of the corpus of neofunctionalist work (and that of Haas in particular), not only to disabuse contemporary students and scholars of the normally static and stylized reading that discussion of the theory provokes, but also to suggest that the conceptual repertoire of neofunctionalism is able to speak directly to current EU studies and comparative regionalism. Neofunctionalism is situated in its social scientific context before the theory's supposed erroneous reliance on the concept of 'spillover' is discussed critically. A case is then made for viewing Haas's neofunctionalism as a dynamic theory that not only corresponded to established social scientific norms, but did so in ways that were consistent with disciplinary openness and pluralism

Simultaneous measurement of the de Haas-van Alphen and the Shubnikov-de Haas effect in a two-dimensional electron system
No full textIn a simultaneous experiment we studied the de Haas–van Alphen (dHvA) and the Shubnikov–de Haas (SdH) effects in a two-dimensional electron system (2DES) in a modulation-doped GaAs∕AlxGa1−xAs heterostructure. For this, a gated 2DES mesa was monolithically integrated with a micromechnical cantilever with an interferometric fiber-optics readout. In situ measurement of the dHvA and SdH oscillations at 300mK in a magnetic field B allowed us to directly compare the variation of the ground state energy and the nonequilibrium transport behavior, respectively. This was done on a 2DES of a small carrier density ns ranging from 5×1010to33×1010cm−2. The wave forms of the dHvA oscillations were nonsinusoidal down to a magnetic field as small as 1.45T. At the same time the zero-field mobility was as low as μe=105cm2/Vs. We found that at fixed B the observed dHvA wave form and amplitude were independent of ns and μe. This was unexpected and in contrast to the established picture in the literature. To understand the dHvA effect quantitatively in a disordered 2DES our data suggest that energetic details of the disorder potentials have to be considered.LMG
The de Haas van Alphen effect near a quantum critical end point in Sr₃Ru₂O₇
No full textHighly correlated electron materials are systems in which many new states of matter can emerge. A particular situation which favours the formation of exotic phases of the electron liquid in complex materials is that where a quantum critical point (QCP) is present in the phase diagram. Neighbouring regions in parameter space reveal unusual physical properties, described as non-Fermi liquid behaviour.
One of the important problems in quantum criticality is to find out how the Fermi surface (FS) of a material evolves near a QCP. The traditional method for studying the FS of materials is the de Haas van Alphen effect (dHvA). A quantum critical end point (QCEP) has been reported in the highly correlated metal Sr₃Ru₂O₇, which is tuned using a magnetic field high enough to perform the dHvA experiment. It moreover features a new emergent phase in the vicinity of the QCEP, a nematic type of electron ordering.
The subject of this thesis is the study of the FS of Sr₃Ru₂O₇ using the dHvA effect. Three aspects were explored. The first was the determination of the FS at fields both above and below that where the QCEP arises. The second was the search for quantum oscillations inside the nematic phase. The third was a reinvestigation of the behaviour of the quasiparticle effective masses near the FS.
In collaboration with angle resolved photoemission spectroscopy experimentalists, a complete robust model for the FS of Sr₃Ru₂O₇ at zero fields was determined. Moreover, the new measurements of the quasiparticle masses revealed that no mass enhancements exist anywhere around the QCEP, in contradiction with previous specific heat data and measurements of the A coefficient of the power law of the resistivity. Finally, we report dHvA oscillations inside the nematic phase, and the temperature dependence of their amplitude suggests strongly that the carriers consist of Landau quasiparticles

de Haas-van Alphen and Shubnikov-de Haas oscillations in RAgSb2 (R = Y, La-Nd, Sm)
No full textde Haas-van Alphen and Shubnikov-de Haas oscillations have been used to study the Fermi surface of the simple tetragonal RAgSb2 series of compounds with R = Y, La-Nd, and Sm. The high quality of the flux-grown single crystals, coupled with very small extremal cross sections of Fermi surface, allow the observation of quantum oscillations at modest fields (H<30 kG) and high temperatures (up to 25 K in SmAgSb2). For H parallel to c, the effective masses, determined from the temperature dependence of the amplitudes, are quite small, typically between 0.07 and 0.5m(0). The topology of the Fermi surface was determined from the angular dependence of the frequencies for R = Y, La, and Sm. In SmAgSb2, antiferromagnetic ordering below 8.8 K is shown to dramatically alter the Fermi surface. For LaAgSb2 and CeAgSb2, the effect of applied hydrostatic pressure on the frequencies was also studied. Finally, the experimental data were compared to the Fermi surface calculated within the tight-binding linear muffin-tin orbital approximation. Overall, the calculated electronic structure was found to be consistent with the experimental data.This article is published as Myers, K. D., S. L. Bud’ko, V. P. Antropov, B. N. Harmon, P. C.
