Boson stars may consist of a new type of light singlet scalar particles withnontrivial self-interactions, and may compose a fraction of the dark matter inthe Universe. In this work, we study the dynamics of boson stars with Liouvilleand logarithmic scalar self-interaction potentials as benchmarks. We perform anumerical analysis as well as a semi-analytic study on how the compactness andthe total mass will deviate from that of the usual boson stars formed with aquartic repulsive self-interaction. We apply the recently suggested Swamplandconjecture to examine whether boson stars with such benchmark potentials belongto the Landscape of a quantum gravity. Using the mass constraint on themacroscopic compact halo object (MACHO) and the cold dark matter (CDM)isocurvature mode constraint from the cosmic microwave background (CMB), wederive the allowed mass range of scalar particles which compose the boson star.We further analyze applications of the lensing of fast radio bursts (FRBs) andthe gravitational wave (GW) detection to probe the presence of such boson starsand constrain the parameter space of their corresponding models. We discuss howthe two types of boson star potentials can be discriminated by the FRB and GWmeasurements.
