Vacuum orbit and spontaneous symmetry breaking in hyperbolic sigma models

We present a detailed study of quantized noncompact, nonlinear SO(1,N) sigma-models in arbitrary space-time dimensions D \geq 2, with the focus on issues of spontaneous symmetry breaking of boost and rotation elements of the symmetry group. The models are defined on a lattice both in terms of a transfer matrix and by an appropriately gauge-fixed Euclidean functional integral. The main results in all dimensions \geq 2 are: (i) On a finite lattice the systems have infinitely many nonnormalizable ground states transforming irreducibly under a nontrivial representation of SO(1,N); (ii) the SO(1,N) symmetry is spontaneously broken. For D =2 this shows that the systems evade the Mermin-Wagner theorem. In this case in addition: (iii) Ward identities for the Noether currents are derived to verify numerically the absence of explicit symmetry breaking; (iv) numerical results are presented for the two-point functions of the spin field and the Noether current as well as a new order parameter; (v) in a large N saddle-point analysis the dynamically generated squared mass is found to be negative and of order 1/(V \ln V) in the volume, the 0-component of the spin field diverges as \sqrt{\ln V}, while SO(1,N) invariant quantities remain finite.Comment: 60 pages, 12 Figures, AMS-Latex; v2: results on vacuum orbit and spontaneous symmetry breaking extended to all dimension

Discourse, justification and critique: towards a legitimate digital copyright regime?

Digitization and the internet have posed an acute economic challenge to rights holders in the cultural industries. Faced with a threat to their form of capital accumulation from copyright infringement, rights holders have used discourse strategically in order to try and legitimate and strengthen their position in the digital copyright debate with governments and media users. In so doing, they have appealed to general justificatory principles – about what is good, right, and just – that provide some scope for opposition and critique, as other groups contest their interpretation of these principles and the evidence used to support them. In this article, we address the relative lack of academic attention paid to the role of discourse in copyright debates by analysing user-directed marketing campaigns and submissions to UK government policy consultations. We show how legitimacy claims are justified and critiqued, and conclude that amid these debates rests some hope of achieving a more legitimate policy resolution to the copyright wars – or at least the possibility of beginning a more constructive dialogue
