Kavli Affiliate: Misao Sasaki | First 5 Authors: Pisin Chen, Misao Sasaki, Dong-han Yeom, Junggi Yoon, | Summary: The information loss paradox associated with black hole Hawking evaporation is an unresolved problem in modern theoretical physics. In this paper, we revisit the entanglement entropy via the Euclidean path integral (EPI) of the quantum state and […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: For a distorted black hole (BH), its ringdown waveform is a superposition of quasi-normal modes (QNMs). In general relativity (GR), the lower order QNM frequencies and damping rates can be well approximated by a polynomial of BH’s dimensionless spin and […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, R. Adak, K. Adamczyk | Summary: We present a reconstruction in early data of the semileptonic decay $B^+ to pi^0 ell^+ nu_ell$, and first results of a reconstruction of the decays $B^+ to rho^0 ell^+ nu_ell$ and $B^0 to rho^- […]

Farinelli, Abigail Sullivan, Tarun N. Bhatia, Hannah Yankello, Rohan Reddy, Younsoo Bae, Rehana K Leak, Sruti Shiva, Louise D McCullough and Devika Soundara Manickam | […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Maodong Gao, Qi-Fan Yang, Qing-Xin Ji, Heming Wang, Lue Wu | Summary: Optical microresonators with high quality ($Q$) factors are essential to a wide range of integrated photonic devices. Steady efforts have been directed towards increasing microresonator $Q$ factors across a variety of platforms. With success […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Jeffrey McKaig, Claudio Ricci, Stéphane Paltani, Shobita Satyapal, | Summary: Recent observations have shown that a large portion of the mid–infrared (MIR) spectrum of active galactic nuclei (AGN) stems from the polar regions. In this paper, we investigate the effects of this polar gas on the X-ray […]
Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: We test the degree to which interacting Bosonic systems can be approximated by a classical field as total occupation number is increased. This is done with our publicly available code repository, href{https://github.com/andillio/QIBS}{QIBS}, a massively parallel solver for […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg, Nicolas Martin, Alexander P. Ji | Summary: We use deep narrowband Ca H&K ($F395N$) imaging taken with the Hubble Space Telescope (HST) to construct the metallicity distribution function (MDF) of Local Group (LG) ultra-faint dwarf (UFD) galaxy Eridanus […]
Kavli Affiliate: Leon Balents | First 5 Authors: Rabindranath Bag, Matthew Ennis, Chunxiao Liu, Sachith E. Dissanayake, Zhenzhong Shi | Summary: We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound Ba3Yb(BO3)3. The results demonstrate the absence of any long-range ordering down to 56 mK. Analysis of the magnetization, susceptibility and specific heat measurements […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Mattis Magg, Itamar Reis, Anastasia Fialkov, Rennan Barkana, Ralf S. Klessen | Summary: Mapping Cosmic Dawn with 21-cm tomography offers an exciting new window into the era of primordial star formation. However, self-consistent implementation of both the process of star formation and the related 21-cm signal is […]
