             abstract = "A possible detection of sub-solar mass ultra-compact objects would 
                         lead to new perspectives on the existence of black holes that are 
                         not of astrophysical origin and/or pertain to formation scenarios 
                         of exotic ultra-compact objects. Both possibilities open new 
                         perspectives for better understanding of our universe. In this 
                         work, we investigate the significance of detection of sub-solar 
                         mass binaries with components mass in the range: 10\−2 
                         M\⊙ up to 1M\⊙, within the expected sensitivity of 
                         the ground-based gravitational waves detectors of third 
                         generation, viz., the Einstein Telescope (ET) and the Cosmic 
                         Explorer (CE). Assuming a minimum of amplitude signal-to-noise 
                         ratio for detection, viz., \ρ = 8, we find that the maximum 
                         horizon distances for an ultra-compact binary system with 
                         components mass 10\−2 M\⊙ and 1M\⊙ are 40 Mpc 
                         and 1.89 Gpc, respectively, for ET, and 125 Mpc and 5.8 Gpc, 
                         respectively, for CE. Other cases are also presented in the text. 
                         We derive the merger rate and discuss consequences on the 
                         abundances of primordial black hole (PBH), fPBH. Considering the 
                         entire mass range [10\−2 1]M\⊙, we find fPBH < 0.70 
                         (<0.06) for ET (CE), respectively.",
