Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early universe. In this work, we extend previous results for GPP of […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Yash Bhargava, Mason Ng, Liang Zhang, Arvind Balasubramanian, Thomas D. Russell | Summary: We present the discovery of X-ray polarization from the neutron star low-mass X-ray binary and Z-source, GX~340$+$0, using an Imaging X-ray Polarimetry Explorer (IXPE) observation in March 2024. Along with the IXPE observation, we […]

Kavli Affiliate: Ke Wang | First 5 Authors: Wenhao He, Tongyang Li, Xiantao Li, Zecheng Li, Chunhao Wang | Summary: The optimal control problem for open quantum systems can be formulated as a time-dependent Lindbladian that is parameterized by a number of time-dependent control variables. Given an observable and an initial state, the goal is […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Leon Shaposhnikov, Eduardo Barredo-Alamilla, Frank Wilczek, Maxim A. Gorlach, | Summary: Spatial structuring of materials at subwavelength scales underlies the concept of metamaterials possessing exotic properties beyond those of the constituent media. Temporal modulation of material parameters enables further functionalities. Here, we show that high-frequency oscillations of […]
Kavli Affiliate: Jing Wang | First 5 Authors: Haosheng Xu, Dongheng Qian, Jing Wang, , | Summary: The use of machine learning methods for predicting the properties of crystalline materials encounters significant challenges, primarily related to input encoding, output versatility, and interpretability. Here, we introduce CrystalBERT, an adaptable transformer-based framework with novel structure that integrates […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We report measurements of the $e^+e^- to Bbar{B}$, $Bbar{B}{}^*$, and $B^*bar{B}{}^*$ cross sections at four energies, 10653, 10701, 10746 and 10805 MeV, using data collected by the Belle~II experiment. We reconstruct one $B$ meson […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jakob M. Helton, George H. Rieke, Stacey Alberts, Zihao Wu, Daniel J. Eisenstein | Summary: The James Webb Space Telescope (JWST) has spectroscopically confirmed numerous galaxies at $z > 10$. While weak rest-ultraviolet emission lines have only been seen in a handful of sources, the stronger rest-optical […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ariful Hoque, Tapas Baug, Lokesh Dewangan, Ke Wang, Tie Liu | Summary: We studied the influence of a massive star on a mid-infrared bubble and its surrounding gas in the IRAS,16489-4431 star-forming region using multi-wavelength data. The {it Spitzer} mid-infrared band images revealed the shocked nature of […]
Kavli Affiliate: Xian Chen | First 5 Authors: Alejandro Torres-Orjuela, Veronica Vazquez-Aceves, Rui Xu, Jin-Hong Chen, Andrea Derdzinski | Summary: GWnext 2024 was a meeting held in the Kavli Institute for Astronomy and Astrophysics at Peking University in March $4^text{th} – 8^text{th}$, 2024. In the meeting researchers at different career stages — with a particular […]
