Duality-covariant particles and exotic branes
Josh O'Connor, David Osten
In this paper we construct duality-covariant worldvolume dynamics of particles and branes. We extend known actions and phase space formulations to include the hidden symmetry…
Higher dualities in exceptional field theory
Guillaume Bossard, Nicolas Boulanger, Josh O'Connor
It was proposed that there exists an -invariant formulation of eleven-dimensional supergravity in which the propagating fields of the theory are realised through an infinit…
Unfolding
Nicolas Boulanger, Paul P. Cook, Josh A. O'Connor +1
We work out the unfolded formulation of the fields in the non-linear realisation of . Using the connections in this formalism, we propose, at the linearised level, an infin…
Dynamics of one-dimensional spin models under the line-graph operator
Marco A. Javarone, Josh A. O'Connor
We investigate the application of the line-graph operator to one-dimensional spin models with periodic boundary conditions. The spins (or interactions) in the original spin structu…
