Title:   Probing Dark Sector with Multiband Gravitational Wave Observations
Abstract:   Gravitational wave observatories, including ground-based detectors LIGO-Virgo-KAGRA, mid-band frequencies CHRONOS, and space-based missions LISA, provide a comprehensive multi-band platform for mapping dark-sector microphysics to physical strain observables. This presentation introduces three analytically controlled frameworks that connect dark matter models to signal generation, stellar microphysics, and wave propagation across distinct frequency regimes. First, high frequency searches for ultralight vector dark matter utilize material-dependent charge-to-mass ratios. Second, two-fluid relativistic field models for neutron stars
admixed with dark matter clarify how interior bosonic or fermionic cores alter stellar profiles, systematically shifting the dimensionless tidal deformability and inducing phase-coherent dephasing in late inspiral waveforms. Third, analytical wave optics lensing through NFW dark matter halos produces closed-form amplification factors, aligning asymptotic frequency limits to resolve diffraction fringes and phase shifts without requiring numerical integration. Collectively, these frameworks establish unified dark-sector probes across the entire multi-band gravitational-wave spectrum.
