Spectral and spatial isolation of single WSe$_2$ quantum emitters using hexagonal boron nitride wrinkles

Posted by klaurent Cornell

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Raphaël S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]

Rozansky-Witten geometry of Coulomb branches and logarithmic knot invariants

Posted by klaurent Tokyo

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Sergei Gukov, Po-Shen Hsin, Hiraku Nakajima, Sunghyuk Park, Du Pei | Summary: By studying Rozansky-Witten theory with non-compact target spaces we find new connections with knot invariants whose physical interpretation was not known. This opens up several new avenues, which include a new formulation of $q$-series invariants […]

Phase-Space Spectral Line De-confusion in Intensity Mapping

Posted by klaurent Caltech

Kavli Affiliate: James J. Bock | First 5 Authors: Yun-Ting Cheng, Tzu-Ching Chang, James J. Bock, , | Summary: Line intensity mapping (LIM) is a promising tool to efficiently probe the three-dimensional large-scale structure by mapping the aggregate emission of a spectral line from all sources that trace the matter density field. Spectral lines from […]

The Cosmological Bootstrap: Spinning Correlators from Symmetries and Factorization

Posted by klaurent Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Carlos Duaso Pueyo, Austin Joyce, Hayden Lee, Guilherme L. Pimentel | Summary: We extend the cosmological bootstrap to correlators involving massless particles with spin. In de Sitter space, these correlators are constrained both by symmetries and by locality. In particular, the de Sitter isometries become […]

Quantum electrodynamics in a topological waveguide

Posted by klaurent Caltech

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

Posted by klaurent Tokyo

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 […]

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

Posted by klaurent Caltech

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 […]
