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 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 of probing scalar-muon interactions that are up to 12 orders of magnitude […]

Coherent excitation of bound electron quantum state with quantum electron wavepackets

Kavli Affiliate: Amnon Yariv | 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 initial quantum (qubit) state, and the free electron is presented as a pre-shaped quantum electron […]

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 […]

Measuring the Effect of Training Data on Deep Learning Predictions via Randomized Experiments

Kavli Affiliate: Anqi Zhang| Summary:We develop a new, principled algorithm for estimating the contribution of training data points to the behavior of a deep learning model, such as a specific prediction it makes. Our algorithm estimates the AME, a quantity that measures the expected (average) marginal effect of adding a data point to a subset […]
