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…

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…
