Probable Dormant Neutron Star in a Short-Period Binary System

Kavli Affiliate: Subo Dong | First 5 Authors: Tsevi Mazeh, Simchon Faigler, Dolev Bashi, Sahar Shahaf, Niv Davidson | Summary: We have identified 2XMM J125556.57+565846.4, at a distance of 600 pc, as a binary system consisting of a normal star and a probable dormant neutron star. Optical spectra exhibit a slightly evolved F-type single star, […]

Is there a sub-parsec-scale jet base in the nearby dwarf galaxy NGC 4395?

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jun Yang, Xiaolong Yang, Joan M. Wrobel, Zsolt Paragi, Leonid I. Gurvits | Summary: NGC 4395 is a dwarf galaxy at a distance of about 4.3 Mpc (scale: ~0.021 pc mas$^{-1}$). It hosts an intermediate-mass black hole (IMBH) with a mass between ~10$^4$ and ~10$^5$ solar […]

Experimental Test of Contextuality based on State Discrimination with a Single Qubit

Kavli Affiliate: Xiang Zhang | First 5 Authors: Qiuxin Zhang, Chenhao Zhu, Yuxin Wang, Liangyu Ding, Tingting Shi | Summary: Exploring quantum phenomena beyond predictions of any classical model has fundamental importance to understand the boundary of classical and quantum descriptions of nature. As a typical property that a quantum system behaves distinctively from a […]

Searching for ultralight scalar dark matter with muonium and muonic atoms

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Yevgeny V. Stadnik, , , , | Summary: Ultralight scalar dark matter may induce apparent oscillations of the muon mass, which may be directly probed via temporal shifts in the spectra of muonium and muonic atoms. Existing datasets and ongoing spectroscopy measurements with muonium are capable […]

Coherent excitation of bound electron quantum state with quantum electron wavepackets

Kavli Affiliate: Amnon Yariv | First 5 Authors: Du Ran, Bin Zhang, Reuven Ianconescu, Aharon Friedman, Jacob Scheuer | Summary: We present a fully quantum model for the excitation of a bound electron based on the free-electron bound-electron resonant interaction (FEBERI) scheme. The bound electron is modeled as a quantum two-level system (TLS) at any […]

Lifetime Limited and Tunable Quantum Light Emission in h-BN via Electric Field Modulation

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Hamidreza Akbari, Souvik Biswas, Pankaj K. Jha, Joeson Wong, Benjamin Vest | Summary: Color centered-based single photon emitters in hexagonal boron nitride (h-BN) have shown promising photophysical properties as sources for quantum light emission. Despite significant advances towards such a goal, achieving lifetime-limited quantum light emission […]

A method to computationally screen for tunable properties of crystalline alloys

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Matthew K. Horton, Kristin A. Persson, , | Summary: Conventionally, high-throughput computational materials searches start from an input set of bulk compounds extracted from material databases, and this set is screened for candidate materials for specific applications. In contrast, many functional materials, and especially […]
