Segmented strings, brane tilings, and the Y-system
David Vegh
I show that the motion of a closed string consisting of segments in AdS can be embedded into the mutation dynamics of the brane tiling. The determinant of the Kas…
Kasner geometries inside holographic superconductors
Lewis Sword, David Vegh
The recent study of holographic superconductors has shown the emergence of a Kasner universe behind the event horizon. This paper serves to add to the discussion by introducing two…
The spectral curve of segmented strings
David Vegh
I show how to compute the spectral curve of piecewise linear Nambu-Goto strings in three-dimensional anti-de Sitter spacetime in terms of `celestial' embedding variables.
On compressing sinh-Gordon solutions
David Vegh
This paper is concerned with a class of approximate non-linear transformations that compress solutions of the (generalized) sinh-Gordon equation into parametrically small regions i…
Relativistic membrane solutions in AdS
David Vegh
In this note we discuss various classical membrane solutions in AdS spacetime: simple embeddings given by polynomials in ambient space, solutions with non-linear waves, and pie…
Pole-skipping and Rarita-Schwinger fields
Nejc Ceplak, David Vegh
In this note we analyse the equations of motion of a minimally coupled Rarita-Schwinger field near the horizon of an anti-de Sitter-Schwarzschild geometry. We find that at special…
