Precise bubble wall velocity in a specific phase transition pattern in the CxSM and beyond
Shihang Tang, Fa Peng Huang, Chikako Idegawa
The bubble wall velocity is a key quantity in cosmological first-order phase transitions, with important implications for electroweak baryogenesis, gravitational wave signals, the…
Scalar dark matter in space-based gravitational-wave detectors: center-of-mass motion, size breathing, and TDI projection
Rui-Yang Hu, Yuan-Zhi Li, An-Qi Wang +3
Ultralight scalar dark matter can make space-based gravitational-wave detectors respond through both the scalar charge of freely falling test masses and scalar-induced changes of l…
Multimessenger search strategy for composite dark matter with white dwarf data and gravitational wave detectors
Siyu Jiang, Aidi Yang, Fa Peng Huang
The nature of dark matter (DM) remains one of the most challenges in modern physics. Composite or macroscopic DM present a compelling alternative to conventional particle DM, yet t…
Model Parameter Reconstruction of Electroweak Phase Transition with TianQin and LISA: Insights from the Dimension-Six Model
Aidi Yang, Chikako Idegawa, Fa Peng Huang
We investigate the capability of TianQin and LISA to reconstruct the model parameters in the Lagrangian of new physics scenarios that can generate an electroweak SFOPT. Taking the…
Primordial Black Hole Formation and Multimessenger Signals in a Complex Singlet Extension of the Standard Model
Fa Peng Huang, Chikako Idegawa, Aidi Yang
We investigate the formation of primordial black holes (PBHs) induced by a first-order electroweak phase transition in a realistic renormalizable framework, the complex singlet ext…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
