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…

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…
