Automated Detection of Antenna Malfunctions in Large-N Interferometers: A Case Study with the Hydrogen Epoch of Reionization Array

Posted by klaurent MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Dara Storer, Joshua S. Dillon, Daniel C. Jacobs, Miguel F. Morales, Bryna J. Hazelton | Summary: We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outliers along known failure modes of […]

Acceleration and deceleration of quantum dynamics based on inter-trajectory travel with fast-forward scaling theory

Posted by klaurent Delft

Kavli Affiliate: Gary A. Steele | First 5 Authors: Shumpei Masuda, Jacob Koenig, Gary A. Steele, , | Summary: Quantum information processing requires fast manipulations of quantum systems in order to overcome dissipative effects. We propose a method to accelerate quantum dynamics and obtain a target state in a shorter time relative to unmodified dynamics, […]

The Effects of Dark Matter and Baryonic Physics on the Milky Way Subhalo Population in the Presence of the Large Magellanic Cloud

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Arka Banerjee, Susmita Adhikari, Yao-Yuan Mao, Risa H. Wechsler | Summary: Given recent developments in our understanding of the Large Magellanic Cloud’s (LMC) impact on the Milky Way’s (MW) dark matter subhalo population, we compare the signatures of dark matter and baryonic physics […]

AdS3’s with and without BTZ’s

Posted by klaurent Chicago

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: This companion paper to arXiv:2109.00065 explores the interpretation of $AdS_3/CFT_2$ duality for $k=(R_{AdS}/lstr)^2<1$ in terms of "non-critical little string theory". We review the underlying fivebrane structure of 1/2-BPS backgrounds for string theory in both the critical dimension and […]

Gravitational Memory and Compact Extra Dimensions

Posted by klaurent Chicago

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Gautam Satishchandran, Savdeep Sethi, , | Summary: We develop a general formalism for treating radiative degrees of freedom near $mathscr{I}^{+}$ in theories with an arbitrary Ricci-flat internal space. These radiative modes are encoded in a generalized news tensor which decomposes into gravitational, electromagnetic, and scalar […]

The free energy of twisting spins in Mn$_3$Sn

Posted by klaurent UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Xiaokang Li, Shan Jiang, Qingkai Meng, Huakun Zuo, Zengwei Zhu | Summary: The magnetic free energy is usually quadratic in magnetic field and depends on the mutual orientation of the magnetic field and the crystalline axes. Tiny in magnitude, this magnetocrystalline anisotropy energy (MAE) is nevertheless indispensable […]

Angular correlations of causally-coherent primordial quantum perturbations

Posted by Chicago

Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Craig Hogan, Stephan S. Meyer, , , | Summary: We consider the hypothesis that nonlocal, omnidirectional, causally-coherent quantum entanglement of inflationary horizons may account for some well-known measured anomalies of Cosmic Microwave Background (CMB) anisotropy on large angular scales. It is shown that causal coherence can […]

Subaru Hyper Suprime-Cam Survey of Cygnus OB2 Complex — I: Introduction, Photometry and Source Catalog

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Saumya Gupta, Jessy Jose, Surhud More, Swagat R. Das, Gregory J. Herczeg | Summary: Low mass star formation inside massive clusters is crucial to understand the effect of cluster environment on processes like circumstellar disk evolution, planet and brown dwarf formation. The young massive association of […]

Epidemic Management and Control Through Risk-Dependent Individual Contact Interventions

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Tapio Schneider, Oliver R. A. Dunbar, Jinlong Wu, Lucas Böttcher, Dmitry Burov | Summary: Testing, contact tracing, and isolation (TTI) is an epidemic management and control approach that is difficult to implement at scale. Here we demonstrate a scalable improvement to TTI that uses data assimilation (DA) […]

The CAMELS Multifield Dataset: Learning the Universe’s Fundamental Parameters with Artificial Intelligence

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Francisco Villaescusa-Navarro, Shy Genel, Daniel Angles-Alcazar, Leander Thiele, Romeel Dave | Summary: We present the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) Multifield Dataset, CMD, a collection of hundreds of thousands of 2D maps and 3D grids containing many different properties of cosmic gas, dark […]
