Migranten Und Internierte:Deutsche in Glasgow, 1864-1918

Für deutsche Migranten des 19. Jahrhunderts war Großbritannien eines der wichtigsten Zielländer innerhalb Europas. Zum ersten Mal wird eine der zahlreichen deutsch-ethnischen Kolonien einer mikrohistorischen Untersuchung unterzogen. Die Perspektive erlaubt quellengestützt genauere Aussagen zu Themenkomplexen wie Wanderungsverhalten, Berufsstruktur oder ethnischer Selbstorganisation. In Glasgow bildete sich ein dichtes Netz an ethnischen Vereinigungen, das sich nach Kriegsausbruch unter dem germanophoben Druck der britischen Öffentlichkeit sowie staatlichen Maßnahmen wie Internierung, Repatriierung oder Enteignung fast vollständig auflöste. Die Glasgower Fallstudie wird durch zahlreiche Querverweise auf andere Regionen und Länder in einen größeren migrationsgeschichtlichen Rahmen eingeordnet. German migrants of the 19th century. Century Britain was one of the main destination countries within Europe. One of the many German ethnic colonies of a micro historical investigation is subjected for the first time. The perspective allows more detailed statements on topics such as migratory behavior, occupational structure or ethnic self-organization source based. A dense network of ethnic associations that almost completely disbanded after war germanophoben pressure from the British public and Government measures such as detention, repatriation or expropriation was formed in Glasgow. The Glasgow case study are classified by numerous cross-references to other regions and countries within a larger migration history.

Negotiating ethnicity, class, and gender:German associational culture in Glasgow 1864-1914

One feature of nineteenth-century German migrant communities was a dense network of religious and secular ethnic institutions in virtually all destination countries. The article is a microhistorical study of a representative German community in Britain. Ethnic institutions in Glasgow included two protestant congregations and a variety of associations fostering sociability, culture and philanthropy. The institutions served as a platform to negotiate questions of ethnicity, class and gender. They were mostly financed by a small elite within the German business community which, in turn, used them to exercise power and confirm social stratification. In the pre-war years, ethnic life was increasingly permeated by nationalism. © 2013 Copyright Taylor and Francis Group, LLC.

Bosonisation as The Hubbard-Stratonovich transformation

The problem of strongly correlated electrons in one dimension attracted attention of condensed matter physicists since early 50’s. After the seminal paper of Tomonaga [1] who suggested the first soluble model in 1950, there were essential achievements reflected in papers by Luttinger [2] (1963) and Mattis and Lieb [3] (1963). A considerable contribution to the understanding of generic properties of the 1D electron liquid has been made by Dzyaloshinskii and Larkin [4] (1973) and Efetov and Larkin [5] (1976). Despite the fact that the main features of the 1D electron liquid were captured and described by the end of 70’s, the investigators felt dissatisfied with the rigour of the theoretical description. The most famous example is the paper by Haldane [6] (1981) where the author developed the fundamentals of a modern bosonisation technique, known as the operator approach. This paper became famous because the author has rigourously shown how to construct the Fermi creation/anihilation operators out of the Bose ones. The most recent example of such a dissatisfaction is the review by von Delft and Schoeller [7] (1998) who revised the approach to the bosonisation and came up with what they called constructive bosonisation.

Granular superconductors:from the nonlinear σ model to the Bose-Hubbard description

We modify a nonlinear σ model (NLσM) for the description of a granular disordered system in the presence of both the Coulomb repulsion and the Cooper pairing. We show that under certain controlled approximations the action of this model is reduced to the Ambegaokar-Eckern-Schön (AES) action, which is further reduced to the Bose-Hubbard (or “dirty-boson”) model with renormalized coupling constants. We obtain an effective action which is more general than the AES one but still simpler than the full NLσM action. This action can be applied in the region of parameters where the reduction to the AES or the Bose-Hubbard model is not justified. This action may lead to a different picture of the superconductor-insulator transition in two-dimensional systems.
