Boundary charges and integral identities for solitons in -dimensional field theories
Sven Bjarke Gudnason, Zhifeng Gao, Yisong Yang
We establish a 3-parameter family of integral identities to be used on a class of theories possessing solitons with spherical symmetry in spatial dimensions. The construction p…
Large-N CP(N-1) sigma model on a finite interval and the renormalized string energy
Alessandro Betti, Stefano Bolognesi, Sven Bjarke Gudnason +2
We continue the analysis started in a recent paper of the large-N two-dimensional CP(N-1) sigma model, defined on a finite space interval L with Dirichlet (or Neumann) boundary con…
A higher-order Skyrme model
Sven Bjarke Gudnason, Muneto Nitta
We propose a higher-order Skyrme model with derivative terms of eighth, tenth and twelfth order. Our construction yields simple and easy-to-interpret higher-order Lagrangians. We f…
A Solitonic Approach to Holographic Nuclear Physics
Salvatore Baldino, Stefano Bolognesi, Sven Bjarke Gudnason +1
We discuss nuclear physics in the Sakai-Sugimoto model in the limit of large number of colors and large 't Hooft coupling . In this limit the individual baryons are descri…
Some exact Bradlow vortex solutions
Sven Bjarke Gudnason, Muneto Nitta
We consider the Bradlow equation for vortices which was recently found by Manton and find a two-parameter class of analytic solutions in closed form on nontrivial geometries with n…
