Effective Lagrangian for Non-Abelian Two-Dimensional Topological Field Theory
Pongwit Srisangyingcharoen, Paul Mansfield
We develop a systematic approach to obtain an effective Lagrangian for 2D non-Abelian topological BF theory. A general expression is presented in a diagrammatic representation cont…
Plahte Diagrams for String Scattering Amplitudes
Pongwit Srisangyingcharoen, Paul Mansfield
Plahte identities are monodromy relations between open string scattering amplitudes at tree level derived from the Koba-Nielsen formula. We represent these identities by polygons i…
Mandelstam formulae for generalised Wilson loops
Chris Curry, Paul Mansfield
We derive Mandelstam formulae for two generalisations of the Wilson loop. In these generalisations path-ordering of Lie algebra generators is replaced by an anti-commuting one dime…
Intersection of world-lines on curved surfaces and path-ordering of the Wilson loop
Chris Curry, Paul Mansfield
We study contact interactions for long world-lines on a curved surface, focusing on the average number of times two world-lines intersect as a function of their end-points. The res…
Entanglement of self interacting scalar fields in an expanding spacetime
Helder Alexander, Gustavo de Souza, Paul Mansfield +2
We evaluate self-interaction effects on the quantum correlations of field modes of opposite momenta for scalar theory in a two-dimensional asymptotically flat Robertson-Walk…
Delta-function Interactions for the Bosonic and Spinning Strings and the Generation of Abelian Gauge Theory
James P. Edwards, Paul Mansfield
We construct contact interactions for bosonic and spinning strings. In the tensionless limit of the spinning string this reproduces the super-Wilson loop that couples spinor matter…
