A simple model of pointlike spacetime defects and implications for photon propagation
M. Schreck, F. Sorba, S. Thambyahpillai
A model in which pointlike defects are randomly embedded in Minkowski spacetime is considered. The distribution of spacetime defects is constructed to be Lorentz-invariant. It does…
Quantum 't Hooft loops of SYM N=4 as instantons of YM_2 in dual groups SU(N) and SU(N)/Z_N
Antonio Bassetto, Shiyamala Thambyahpillai
A relation between circular 1/2 BPS 't Hooft operators in 4d N=4 SYM and instantonic solutions in 2d Yang-Mills theory (YM_2) has recently been conjectured. Localization indeed pre…
Correlators of supersymmetric Wilson loops at weak and strong coupling
Antonio Bassetto, Luca Griguolo, Fabrizio Pucci +3
We continue our study of the correlators of a recently discovered family of BPS Wilson loops in N=4 supersymmetric U(N) Yang-Mills theory. We perform explicit computations at weak…
Correlators of supersymmetric Wilson-loops, protected operators and matrix models in N=4 SYM
A. Bassetto, L. Griguolo, F. Pucci +3
We study the correlators of a recently discovered family of BPS Wilson loops in supersymmetric U(N) Yang-Mills theory. When the contours lie on a two-sphere in the spa…
Discretizing Gravity in Warped Spacetime
Lisa Randall, Matthew D. Schwartz, Shiyamala Thambyahpillai
We investigate the discretized version of the compact Randall-Sundrum model. By studying the mass eigenstates of the lattice theory, we demonstrate that for warped space, unlike fo…
A Closer Look at Two Branes in an Bulk
Shiyamala Thambyahpillai
We investigate a scenario with two branes in an bulk. In this scenario there are two gravitons and we investigate the role played by each of them for different posi…
