On the exponentially small corrections to ${cal N} = 2$ superconformal correlators at large R-charge

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, , , , | Summary: In this note we consider Coulomb-branch chiral primary correlation functions in ${cal N} = 2$ superconformal QCD with gauge group $SU(2)$, in the limit of large R-charge ${cal J} = 2n$ for the chiral primary operators $[{cal O}(x)]^ n$ with […]

Non-unitary TQFTs from 3D $mathcal{N}=4$ rank 0 SCFTs

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dongmin Gang, Sungjoon Kim, Kimyeong Lee, Myungbo Shim, Masahito Yamazaki | Summary: We propose a novel procedure of assigning a pair of non-unitary topological quantum field theories (TQFTs), TFT$_pm [mathcal{T}_{rm rank ;0}]$, to a (2+1)D interacting $mathcal{N}=4$ superconformal field theory (SCFT) $mathcal{T}_{rm rank ;0}$ of rank 0, […]

To H0 or not to H0?

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: This paper investigates whether changes to late time physics can resolve the `Hubble tension’. It is argued that many of the claims in the literature favouring such solutions are caused by a misunderstanding of how distance ladder measurements actually work […]

A Lunar Farside Low Radio Frequency Array for Dark Ages 21-cm Cosmology

Kavli Affiliate: Albert Stebbins | First 5 Authors: Jack Burns, Gregg Hallinan, Tzu-Ching Chang, Marin Anderson, Judd Bowman | Summary: An array of low-frequency dipole antennas on the lunar farside surface will probe a unique, unexplored epoch in the early Universe called the Dark Ages. It begins at Recombination when neutral hydrogen atoms formed, first […]

Characterization of Skipper CCDs for Cosmological Applications

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Alex Drlica-Wagner, Edgar Marrufo Villalpando, Judah O’Neil, Juan Estrada, Stephen Holland | Summary: We characterize the response of a novel 250 $mu$m thick, fully-depleted Skipper Charged-Coupled Device (CCD) to visible/near-infrared light with a focus on potential applications for astronomical observations. We achieve stable, single-electron resolution with readout […]

An Information Paradox and Its Resolution in de Sitter Holography

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Hao Geng, Yasunori Nomura, Hao-Yu Sun, , | Summary: We formulate a version of the information paradox in de Sitter spacetime and show that it is solved by the emergence of entanglement islands in the context of the DS/dS correspondence; in particular, the entanglement entropy of a […]

Picosecond Laser Ablation of Millimeter-Wave Subwavelength Structures on Alumina and Sapphire

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Qi Wen, Elena Fadeeva, Shaul Hanany, Jürgen Koch, Tomotake Matsumura | Summary: We use a 1030 nm laser with 7 ps pulse duration and average power up to 100 W to ablate pyramid-shape subwavelength structures (SWS) on alumina and sapphire. The SWS give an effective and cryogenically […]

Modelling the Multiwavelength Variability of Mrk 335 using Gaussian Processes

Kavli Affiliate: Erin Kara | First 5 Authors: Ryan-Rhys Griffiths, Jiachen Jiang, Douglas J. K. Buisson, Dan R. Wilkins, Luigi C. Gallo | Summary: The optical and UV variability of the majority of AGN may be related to the reprocessing of rapidly-changing X-ray emission from a more compact region near the central black hole. Such […]
