Bøger af Germán Sierra

Using Duchamp's technique of the 'readymade', Germán Sierra has transfromed plundered snippets from medival and scientific journals and repurposed them as poetry. The resulting pieces have a glacial autistic beauty reminiscent of the paintings of de Chirico and Carra, and the early writings of J G Ballard.

This volume, intended as a contribution to the 10th birthday of high Tc-superconductivity, conveys the essential ideas of the field and addresses researchers as well as graduate students. A special feature is the pedagogical treatment of a variety of modern computational methods to deal with non-pertubative effects in strongly correlated systems. Among the topics treated are the Hubbard models, real space renormalization group methods, quantum phase transitions, the non-linear sigma model, spin ladders and layers, and the quantum Hall effect.

As theoretical physicists, our starting viewpoint to address the problem of strongly correlat ed ferlnion systems and related issues of modern condensed matter physics *is the renormalization group approach applied both to quantU111 field theory and statistical physics.
