Perturbations of vortex ring pairs
Steven S. Gubser, Bart Horn, Sarthak Parikh
We study pairs of co-axial vortex rings starting from the action for a classical bosonic string in a three-form background. We complete earlier work on the phase diagram of classic…
Nonlinear Sigma Models with Compact Hyperbolic Target Spaces
Steven Gubser, Zain H. Saleem, Samuel S. Schoenholz +2
We explore the phase structure of nonlinear sigma models with target spaces corresponding to compact quotients of hyperbolic space, focusing on the case of a hyperbolic genus-2 Rie…
Fermionic Response in Finite-Density ABJM Theory with Broken Symmetry
Oliver DeWolfe, Steven S. Gubser, Oscar Henriksson +1
We calculate fermionic response in domain wall backgrounds of four-dimensional gauged supergravity interpolating between distinct stable AdS vacua. The backgrounds, found by Bobev…
Segmented Strings in
Nele Callebaut, Steven S. Gubser, Andreas Samberg +1
We study segmented strings in flat space and in . In flat space, these well known classical motions describe strings which at any instant of time are piecewise linear. In $A…
