Direct Detection of Light Self-Interacting Dark Matter via Electronic Collective Excitations
Wen-Na Yang, Wu-Long Xu, Wenyu Wang +1
Models of light dark matter often invoke a light mediator to facilitate interactions with the Standard Model. If sufficiently light, this mediator can induce long-range self-intera…
Ground State and Collective Modes of Bose-Einstein Condensates in Newtonian and MOND-inspired gravitational potentials
Ning Liu
We analytically and numerically study the ground state and collective dynamics of Bose-Einstein condensates in two traps: a Newtonian potential and a logarithmic potential inspired…
Anisotropic dispersion relation of ultralight Bose gases in modified Newtonian dynamics
Ning Liu
We investigate the dispersion relation of collective modes in ultralight Bose gases under Modified Newtonian Dynamics (MOND). Starting from the coupled Gross-Pitaevskii and MOND Po…
Constraints on Axion-Like Particles with the Silicon Detector at a Nuclear Reactor
Yuanlin Gong, Jun Guo, Ning Liu +2
Axion and axion-like particles (ALPs), predicted in various extensions of the Standard Model, can be abundantly produced in nuclear reactors via the Primakoff process. In this work…
Direct Detection of Leptophobic Dark Matter with Electronic Collective Excitations
Yuanlin Gong, Yifan Hu, Ning Liu +2
Some new-generation dark matter detection experiments are primarily designed to search for the dark matter-electron interactions, but they can also be utilized to probe models in w…
Detecting Collective Excitations in Self-Gravitating Bose-Einstein Condensates via Faraday Waves
Ning Liu, Guodong Cheng
We propose Faraday waves as a probe for collective excitations in self-gravitating Bose-Einstein condensates (SGBECs). Using a semi-classical approach based on linear stability ana…
Detecting light dark matter with prompt-delayed events in neutrino experiments
Yuanlin Gong, Feiran Lin, Ning Liu +2
We demonstrate the prompt-delayed signals induced by knockout neutrons from the quasi-elastic scattering in neutrino experiments provides a new avenue for detecting light dark matt…
Search for nearly degenerate higgsinos via photon fusion with the semileptonic channel at the LHC
Hang Zhou, Ning Liu
Electroweak scale higgsinos with a nearly degenerate spectrum in supersymmetric models are well-motivated, but generally less constrained at collider experiments as the decay produ…
