Probing Purely Inelastic Scalar Dark Matter Across Colliders and Gravitational Wave Observatories
Jinhui Guo, Jia Liu, Chenhao Peng +1
We propose and study a purely inelastic scalar dark matter model, where two real scalars-dark matter and its excited partner interact with the Standard Model via a Hi…
Ultimate Quantum Precision Limit at Colliders: Conditions and Case Studies
Tengyu Ai, Qi Bi, Yuxin He +2
We investigate whether collider experiments can reach the quantum limit of precision, defined by the quantum Fisher information (QFI), using only classical observables such as part…
Scattering Entanglement Entropy and Its Implications for Electroweak Phase Transitions
Jia Liu, Masanori Tanaka, Xiao-Ping Wang +2
We investigate the connection between the entanglement entropy in scattering processes and the dynamics of electroweak phase transitions. Recent work has shown that the scattering…
Long-lived Sterile Neutrino Searches at Future Muon Colliders
Qi Bi, Jinhui Guo, Jia Liu +2
We explore the potential of studying sterile neutrinos at a future high-energy muon collider, where these particles can generate small active neutrino masses via the seesaw mechani…
Dark Matter Search with a Resonantly-Coupled Hybrid Spin System
Kai Wei, Zitong Xu, Yuxuan He +9
Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of dark matter (DM). Traditional axion DM experiments rely on sharp re…
Particle Conversions Beyond the WKB Approximation and Solar-Induced Gravitational Waves from Dark Photon Dark Matter
Tengyu Ai, Yuxuan He, Jia Liu +2
We investigate the conversion of kinetic mixing dark photon dark matter into gravitational waves within the magnetic field of the Sun. Our study reveals that the WKB approximation…
