Kavli Affiliate: Misao Sasaki | First 5 Authors: Samuel Passaglia, Misao Sasaki, , , | Summary: We show that primordial black holes can be produced from the collapse of large isocurvature perturbations of the cold dark matter. We develop a novel procedure to compute the resulting black hole abundance by studying matched perturbations of matter-only […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Yong Gao, Xiao-Yu Lai, Lijing Shao, Ren-Xin Xu, | Summary: The strong interactions at low energy scales determine the state of the supranuclear matter in the pulsar-like compact objects. It is proposed that the bulk strong matter could be composed of strangeons, which are quark clusters with […]
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 […]
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, […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
