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 | 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 […]

Polarized X-rays Constrain The Disk-Jet Geometry in a Black Hole X-ray Binary

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Henric Krawczynski, Fabio Muleri, Michal DovĨiak, Alexandra Veledina, Nicole Rodriguez Cavero | Summary: In a black hole X-ray binary (XRB) system, gas accreted from a normal star onto a black hole glows brightly in X-rays. We report on an observation of the XRB Cygnus X-1 (Cyg […]
