The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Eleonora Di Valentino, Jackson Levi Said, Adam Riess, Agnieszka Pollo, Vivian Poulin | Summary: The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades. This concordance model is constructed by a […]

The Receding Cosmic Shoreline of Mid-to-Late M Dwarfs: Measurements of Active Lifetimes Worsen Challenges for Atmosphere Retention by Rocky Exoplanets

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Emily K Pass, David Charbonneau, Andrew Vanderburg, , | Summary: Detecting and characterizing the atmospheres of terrestrial exoplanets is a key goal of exoplanetary astronomy, one that may now be within reach given the upcoming campaign to conduct a large-scale survey of rocky M-dwarf worlds with the […]

Fault-tolerant correction-ready encoding of the [[7,1,3]] Steane code on a 2D grid

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Andrea Rodriguez-Blanco, Ho Nam Nguyen, K. Birgitta Whaley, , | Summary: Practical quantum computation heavily relies on the ability to perform quantum error correction in a fault-tolerant manner. Fault-tolerant encoding is a critical first step, and careful consideration of the error correction cycle that follows is essential […]

Polarization Position Angle Swing and the Rotating Vector Model of Repeating Fast Radio Bursts

Posted by dbos Peking

Kavli Affiliate: Kejia Lee | First 5 Authors: Xiaohui Liu, Heng Xu, Jiarui Niu, Yongkun Zhang, Jinchen Jiang | Summary: Fast radio bursts (FRBs), typically highly polarized, usually have a nearly constant polarization position angle (PA) during each burst. Some bursts show significant PA variations, and one of them was claimed to have a PA […]

Constraints on Non-Thermal Pressure at galaxy cluster outskirts from a Joint SPT and XMM-Newton Analysis

Posted by dbos MIT

Kavli Affiliate: Catherine E. Grant | First 5 Authors: Arnab Sarkar, Michael McDonald, Lindsey Bleem, Mark Bautz, Bradford A. Benson | Summary: We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8–1.7$times$10$^{15}$ M$_{odot}$) spanning a redshift range of 0.16 to 0.35. Employing a novel SZ+X-ray fitting technique, we effectively […]

Universality of Rényi Entropy in Conformal Field Theory

Posted by dbos Tokyo

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Yuya Kusuki, Hirosi Ooguri, Sridip Pal, , | Summary: We use the thermal effective theory to prove that, for the vacuum state in any conformal field theory in $d$ dimensions, the $n$-th R’enyi entropy $S_A^{(n)}$ behaves as $S_A^{(n)} = frac{f}{(2pi n)^{d-1}} frac{ {rm Area}(partial A)}{(d-2)epsilon^{d-2}}left(1+O(n)right)$ in the […]

Exchange cross-talk mitigation in dense quantum dot arrays

Posted by dbos Delft

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Daniel Jirovec, Pablo Cova Fariña, Stefano Reale, Stefan D. Oosterhout, Xin Zhang | Summary: Coupled spins in semiconductor quantum dots are a versatile platform for quantum computing and simulations of complex many-body phenomena. However, on the path of scale-up, cross-talk from densely packed electrodes poses a severe […]
