Solitons in Noncommutative Gauge Theory
We present a unified treatment of classical solutions of noncommutative gauge theories. We find all solutions of the noncommutative Yang-Mills equations of motion in 2 dimensions; and show that they are labeled by two integers—the rank of the gauge group and the magnetic charge. The magnetic vortex solutions are unstable in 2+1 dimensions, but correspond to the full, stable BPS solutions of N =...
متن کاملUnstable Solitons in Noncommutative Gauge Theory
We find a class of exact solutions of noncommutative gauge theories corresponding to unstable non-BPS solitons. In the two-dimensional euclidean (or 2+1 dimensional lorentzian) U(1) theory we find localized solutions carrying nonzero magnetic flux. In four euclidean dimensions we find non-BPS solutions with the same Pontrjagin charge but greater energy than the usual self-dual Yang-Mills instan...
متن کاملGauge theory solitons on noncommutative cylinder
Abstract We generalize to noncommutative cylinder the solution generation technique, originally suggested for gauge theories on noncommutative plane. For this purpose we construct partial isometry operators and complete set of orthogonal projectors in the algebra AC of the cylinder, and an isomorphism between the free module AC and its direct sum AC⊕FC with the Fock module on the cylinder. We c...
متن کاملOn Solitons in Noncommutative Gauge Theories
Recently there has been a revival of interest in noncommutative gauge theories. They are interesting examples of nonlocal field theories which in the certain limit (of large noncommutativity) become essentially equivalent to the large N ordinary gauge theories ; certain supersymmetric versions of noncommutative gauge theories arise as α′ → 0 limit of theories on Dp-branes in the presence of bac...
متن کاملNoncommutative Tachyonic Solitons. Interaction with Gauge Field
We show that in the presence of U(1) non-commutative YM interaction the noncommutative tachyonic system exhibits solitonic solutions (even) for finite value of non commutativity parameter θ.
