Journal ArticleDOI
Boson Stars as Solitary Waves
TL;DR: In this paper, the authors studied the nonlinear equation i theta t psi = (root-Delta+m(2) -m) psi - (vertical bar x vertical bar(-1) * vertical bar psi vertical bar(2)) psi on R-3.
Journal ArticleDOI
On a sharp transition from area law to perimeter law in a system of random surfaces
TL;DR: In this paper, a phase transition associated with the spontaneous formation of infinite surface sheets in a Bernoulli system of random plaquettes is studied, and the transition is manifested by a change in the asymptotic behavior of the probability of the formation of a surface spanning a prescribed loop.
Journal ArticleDOI
The geometry of WZW branes
TL;DR: The structure constants of the algebra of boundary operators coincide with specific entries of fusing matrices in rational conformal field theory as mentioned in this paper, and it has been shown that the pentagon identity and tetrahedral symmetry imply that the structure constants coincide with the corresponding entries of the fusing matrix.
Journal ArticleDOI
Higgs phenomenon without symmetry breaking order parameter
TL;DR: A complete set of gauge-invariant, observable composite fields for such theories, local ones and ones localized near strings (paths) is constructed in this article, and the validity of standard perturbation theory, based on assuming that 〈ϕ〉 ≠ 0, is examined.
Journal ArticleDOI
Massless phases and symmetry restoration in abelian gauge theories and spin systems
Jürg Fröhlich,Thomas Spencer +1 more
TL;DR: In this article, the existence of a deconfining transition to a massless (QED) phase in the four-dimensional U(1) lattice gauge theory was proved.
