Sideband Structure of Axion Electrodynamics
Run-Min Yao, Xiao-Jun Bi, Peng-Fei Yin +1
We develop a Floquet--Bloch sideband formulation of the linearized Maxwell--axion system in a coherent periodic axion background. Linearizing around prescribed magnetic and axion f…
Evolution of Compact Stellar Systems in Ultralight Dark Matter Halos: Dependence on Stellar and Dark Matter Parameters
Yu-Ming Yang, Xiao-Jun Bi, Long Wang +1
Compact stellar systems are often used to place stringent constraints on the particle mass of ultralight dark matter (ULDM), as the heating effect induced by wave interference can…
Constraints on Self-Interacting Fuzzy Dark Matter from the Stellar Kinematics of the Dwarf Galaxy Leo II
Yi Zhao, Yu-Ming Yang, Xiao-Jun Bi +1
The one-parameter fuzzy dark matter (FDM) model has faced increasingly stringent constraints from both Lyman- forest observations and local measurements of dwarf galaxies. A na…
Resonant Photon-Axion Mixing Driven by Dark Matter Oscillations
Run-Min Yao, Xiao-Jun Bi, Peng-Fei Yin +1
Wave propagation in periodically time-dependent media can exhibit driven mode conversion that is absent in static or adiabatic descriptions. We show that photon propagation through…
Collapse versus Disruption: The Fate of Compact Stellar Systems in Ultralight Dark Matter Halos
Yu-Ming Yang, Xiao-Jun Bi, Long Wang +1
Interference of the ultralight dark matter (ULDM) field generates time-varying gravitational potential fluctuations, which stochastically heat stellar systems embedded in ULDM halo…
Axion-like Dark Matter Search with Space-based Gravitational Wave Detectors
Run-Min Yao, Xiao-Jun Bi, Peng-Fei Yin +1
We propose a novel modification to the optical benches of space-based gravitational wave detectors (SGWDs) to enable the detection of axion-like dark matter (ALDM)-induced birefrin…
