Quantum complex sine-Gordon dressed boundaries
Peter Bowcock, James Umpleby
In this paper we investigate the quantum reflection factor for the CSG dressed boundary, previously constructed by dressing the Dirichlet boundary with the integrable CSG defect. W…
Q-balls, Integrability and Duality
Peter Bowcock, David Foster, Paul Sutcliffe
This paper is concerned with the dynamics and interactions of Q-balls in (1+1)-dimensions. The asymptotic force between well-separated Q-balls is calculated to show that Q-balls ca…
Defects and Dressed Boundaries in Complex Sine-Gordon Theory
Peter Bowcock, James Umpleby
In this paper we constructed integrable defects in complex sine-Gordon theory. Soliton and particle interactions with the defect are analysed. Defects are used to dress Dirichlet b…
Quantum complex sine-Gordon model on a half line
Peter Bowcock, Georgios Tzamtzis
The quantum complex sine-Gordon model on a half line is studied. The quantum spectrum of boundary bound states using the the semi-classical method of Dashen, Hasslacher and Neveu i…
Using D-Strings to Describe Monopole Scattering - Numerical Calculations
Jessica K. Barrett, Peter Bowcock
We calculate the energy radiated during the scattering of two D-strings stretched between two D3-branes, working from the Born-Infeld action for the D-strings. The ends of the D-st…
Affine Toda field theories with defects
P. Bowcock, E. Corrigan, C. Zambon
A Lagrangian approach is proposed and developed to study defects within affine Toda field theories. In particular, a suitable Lax pair is constructed together with examples of cons…
