Singular Monopoles via the Nahm Transform
Sergey A. Cherkis, Brian Durcan
We present explicit expressions for the fields of a charge one BPS monopole with two Dirac singularities. These are solutions of the nonlinear Bogomolny equations with the gauge gr…
The 't Hooft-Polyakov Monopole in the Presence of a 't Hooft Operator
Sergey A. Cherkis, Brian Durcan
We present explicit BPS field configurations representing one nonabelian monopole with one minimal weight 't Hooft operator insertion. We explore the SO(3) and SU(2) gauge groups.…
On String S-matrix, Bound States and TBA
Gleb Arutyunov, Sergey Frolov
The study of finite J effects for the light-cone AdS superstring by means of the Thermodynamic Bethe Ansatz requires an understanding of a companion 2d theory which we call the mir…
Fluctuations around the Tachyon Vacuum in Open String Field Theory
O-Kab Kwon, Bum-Hoon Lee, Chanyong Park +1
We consider quadratic fluctuations around the tachyon vacuum numerically in open string field theory. We work on a space spanned by basis string states used…
d=4+1 gravitating nonabelian solutions with bi-azimuthal symmetry
Eugen Radu, Ya. Shnir, D. H. Tchrakian
We construct static, asymptotically flat solutions of SU(2) Einstein-Yang-Mills theory in 4+1 dimensions, subject to bi-azimuthal symmetry. Both particle-like and black hole soluti…
A Journey Between Two Curves
Sergey A. Cherkis
A typical solution of an integrable system is described in terms of a holomorphic curve and a line bundle over it. The curve provides the action variables while the time evolution…
