Quantum electrodynamics in a topological waveguide

Kavli Affiliate: Oskar Painter | First 5 Authors: Eunjong Kim, Xueyue Zhang, Vinicius S. Ferreira, Jash Banker, Joseph K. Iverson | Summary: While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the topology of the photonic […]

S-duality and correlation functions at large R-charge

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Shunsuke Maeda, Domenico Orlando, Susanne Reffert, Masataka Watanabe | Summary: We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in $SU(2)$ $mathcal{N}=2$ SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of […]

Precision measurement of the ${cal B}(Υ(3S)toτ^+τ^-)/{cal B}(Υ(3S)toμ^+μ^-)$ ratio

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: J. P. Lees, V. Poireau, V. Tisserand, E. Grauges, A. Palano | Summary: We report on a precision measurement of the ratio ${cal R}_{taumu}^{Upsilon(3S)} = {cal B}(Upsilon(3S)totau^+tau^-)/{cal B}(Upsilon(3S)tomu^+mu^-)$ using data collected with the BaBar detector at the SLAC PEP-II $e^+e^-$ collider. The measurement is based on […]

Witten Anomaly in 4d Heterotic Compactificaitons with N = 2 Supersymmetry

Kavli Affiliate: Taizan Watari | First 5 Authors: Yuichi Enoki, Yotaro Sato, Taizan Watari, , | Summary: We showed that there is no SU(2) Witten anomaly in a large class of 4d N = 2 supersymmetric Heterotic string compactifications. The consistency conditions we consider are the modularity of the new supersymmetric index, the integrality of […]

Learning-based super interpolation and extrapolation for speckled image reconstruction

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Huanhao Li, Zhipeng Yu, Yunqi Luo, Shengfu Cheng, Lihong V. Wang | Summary: Speckles arise when coherent light interacts with biological tissues. Information retrieval from speckles is desired yet challenging, requiring understanding or mapping of the multiple scattering process, or reliable capability to reverse or compensate […]

The formation of dusty cold gas filaments from galaxy cluster simulations

Kavli Affiliate: Michael McDonald | First 5 Authors: Yu Qiu, Tamara Bogdanovic, Yuan Li, Michael McDonald, Brian R. McNamara | Summary: Galaxy clusters are the most massive collapsed structures in the universe whose potential wells are filled with hot, X-ray emitting intracluster medium. Observations however show that a significant number of clusters (the so-called cool-core […]

Defining the $T overline{T}$ Deformation on $mathrm{AdS}_2$

Kavli Affiliate: Savdeep Sethi | First 5 Authors: T. Daniel Brennan, Christian Ferko, Emil Martinec, Savdeep Sethi, | Summary: We show that the $T overline{T}$ deformation of two-dimensional quantum field theory on $mathrm{AdS}_2$ is well-defined and solvable at the quantum level. Flow equations for the energy spectrum and partition function are derived in analogy with […]
