The appearence of the resolved singular hypersurface {x_0}{x_1}-{{x_2}^n} =0 in the classical phase space of the Lie group SU(n)
Samir K. Paul, Siddhartha Sen
A classical phase space with a suitable symplectic structure is constructed together with functions which have Poisson brackets algebraically identical to the Lie algebra structure…
Icosahedral Skyrmions
Richard Battye, Conor Houghton, Paul Sutcliffe
In this paper we aim to determine the baryon numbers at which the minimal energy Skyrmion has icosahedral symmetry. By comparing polyhedra which arise as minimal energy Skyrmions w…
Tachyon Dynamics and the Effective Action Approximation
N. D. Lambert, I. Sachs
Recently effective actions have been extensively used to describe tachyon condensation in string theory. While the various effective actions which have appeared in the literature h…
Multicloud solutions with massless and massive monopoles
Conor J. Houghton, Erick J. Weinberg
Certain spontaneously broken gauge theories contain massless magnetic monopoles. These are realized classically as clouds of non-Abelian fields surrounding one or more massive mono…
Black Hole Decay as Geodesic Motion
Kumar S. Gupta, Siddhartha Sen
We show that a formalism for analyzing the near-horizon conformal symmetry of Schwarzschild black holes using a scalar field probe is capable of describing black hole decay. The eq…
