Alice and Bob in an expanding spacetime (2015)
Journal Article
Alexander, H., de Souza, G., Mansfield, P., & Sampaio, M. (2015). Alice and Bob in an expanding spacetime. European Physical Society Letters, 111(6), Article 60001. https://doi.org/10.1209/0295-5075/111/60001

We investigate the teleportation of a qubit between two observers Alice and Bob in an asymptotically flat Robertson-Walker expanding spacetime. We use scalar or fermionic field modes inside Alice's and Bob's ideal cavities and show the degradation of... Read More about Alice and Bob in an expanding spacetime.

QED as the tensionless limit of the spinning string with contact interaction (2015)
Journal Article
Edwards, J. P., & Mansfield, P. (2015). QED as the tensionless limit of the spinning string with contact interaction. Physics Letters B, 746, 335-340. https://doi.org/10.1016/j.physletb.2015.05.024

QED with spinor matter is argued to correspond to the tensionless limit of spinning strings with contact interactions. The strings represent electric lines of force with charges at their ends. The interaction is constructed from a delta-function on t... Read More about QED as the tensionless limit of the spinning string with contact interaction.

The fermion content of the Standard Model from a simple world-line theory (2015)
Journal Article
Mansfield, P. (2015). The fermion content of the Standard Model from a simple world-line theory. Physics Letters B, 743, 353-356. https://doi.org/10.1016/j.physletb.2015.02.061

We describe a simple model that automatically generates the sum over gauge group representations and chiralities of a single generation of fermions in the Standard Model, augmented by a sterile neutrino. The model is a modification of the world-line... Read More about The fermion content of the Standard Model from a simple world-line theory.

Delta-function interactions for the bosonic and spinning strings and the generation of Abelian gauge theory (2015)
Journal Article
Edwards, J., & Mansfield, P. (2015). Delta-function interactions for the bosonic and spinning strings and the generation of Abelian gauge theory. Journal of High Energy Physics, 2015(1), Article 127. https://doi.org/10.1007/jhep01%282015%29127

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 to Abelian gauge theory. Adding boundary terms that quantise the moti...
