abstract

The chiral gravitational wave background (GWB) can be produced by axion-like fields in the early universe. We perform parameter estimation for two types of chiral GWB with the LISA-Taiji network: axion-dark photon coupling and axion-Nieh-Yan coupling. We estimate the spectral parameters of these two mechanisms induced by axion and determine the normalized model parameters using the Fisher information matrix. For highly chiral GWB signals that we choose to analyze in the mHz band, the normalized model parameters are constrained with a relative error less than $6.7\%$ (dark photon coupling) and $2.2\%$ (Nieh-Yan coupling) at the one-sigma confidence level. The circular polarization parameters are constrained with a relative error around $21\%$ (dark photon coupling) and $6.2\%$ (Nieh-Yan coupling) at the one-sigma confidence level.

  1. Correlated parity violation in gravity and electromagnetism from five-dimensional spacetime

    gr-qc 2026-08 conditional novelty 7.0 of 10

    A five-dimensional teleparallel Kaluza-Klein action produces a single parameter-free prediction: the electromagnetic helicity dispersion shift is exactly six times the gravitational one.

  2. Distinguishing Monochromatic Signals in LISA and Taiji: Ultralight Dark Matter versus Gravitational Waves

    hep-ph 2025-06 conditional novelty 7.0 of 10

    Null-response interferometric channels can separate monochromatic ultralight dark matter signals from gravitational waves in LISA and Taiji, most effectively at high frequencies.

  3. Beyond general relativity: gravitational waves in non-minimally coupled theories

    gr-qc 2025-10 conditional novelty 5.0 of 10

    A generalized propagation parameterization for gravitational-wave strains is extended to O(H²) and O(H′), then mapped to Kalb-Ramond, axion-dilaton–Chern-Simons–Gauss-Bonnet, and U(1) dark-photon models.

  4. Fixed-Time Voltage Regulation for Boost Converters via Unit-Safe Saturating Functions

    eess.SY 2025-08 unverdicted novelty 4.0 of 10

    A fixed-time feedback controller for boost converters uses a new class of saturating functions, observers, and adaptive gains to regulate output voltage within a bounded settling time under unknown load resistance.
