Monopole-antimonopole: interaction, scattering and creation
Ayush Saurabh, Tanmay Vachaspati
The interaction of a magnetic monopole-antimonopole pair depends on their separation as well as on a second "twist" degree of freedom. This novel interaction leads to a non-trivial…
String Production in the Abelian Higgs Vacuum
Ayush Saurabh, Tanmay Vachaspati
We numerically study string production by evolving classical Abelian-Higgs gauge field wavepackets. Initial conditions are constructed for the propagation of a single wavepacket an…
Monopole-antimonopole Interaction Potential
Ayush Saurabh, Tanmay Vachaspati
We numerically study the interactions of twisted monopole-antimonopole pairs in the 't Hooft-Polyakov model for a range of values of the scalar to vector mass ratio. We also recove…
A Stochasticity Threshold in Holography and and the Instability of AdS
Pallab Basu, Chethan Krishnan, Ayush Saurabh
We give strong numerical evidence that a self-interacting probe scalar field in AdS, with only a few modes turned on initially, will undergo fast thermalization only if it is above…
Strings vs Spins on the Null Orbifold
K. Surya Kiran, Chethan Krishnan, Ayush Saurabh +1
We study the null orbifold singularity in 2+1 d flat space higher spin theory as well as string theory. Using the Chern-Simons formulation of 2+1 d Einstein gravity, we first obser…
Low Tension Strings on a Cosmological Singularity
Ben Craps, Chethan Krishnan, Ayush Saurabh
It has recently been argued that the singularity of the Milne orbifold can be resolved in higher spin theories. In string theory scattering amplitudes, however, the Milne singulari…
