Exotic nonrelativistic string Casalbuoni, Roberto Gomis Torné, Joaquim Longhi, Giorgio Teoria de camps (Física) Relativitat (Física) Field theory (Physics) Relativity (Physics) We construct a classical nonrelativistic string model in 3+1 dimensions. The model contains a spurion tensor field that is responsible for the noncommutative structure of the model. Under double-dimensional reduction the model reduces to the exotic nonrelativistic particle in 2+1 dimensions. 2010-05-06T12:44:04Z 2010-05-06T12:44:04Z 2007 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevD.76.126004 Physical Review D, 2007, vol. 76, núm. 12, p. 126004-1-126004-6 http://dx.doi.org/10.1103/PhysRevD.76.126004 (c) The American Physical Society, 2007 info:eu-repo/semantics/openAccess The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
