Phys. Rev. Lett. 101, 211301 (2008) [4 pages]Gravitational Waves from Fragmentation of a Primordial Scalar Condensate into Q BallsReceived 28 July 2008; revised 6 October 2008; published 19 November 2008 A generic consequence of supersymmetry is the formation of a scalar condensate along the flat directions of the potential at the end of cosmological inflation. This condensate is usually unstable, and it can fragment into nontopological solitons, Q balls. The gravitational waves produced by the fragmentation can be detected by the Laser Interferometer Space Antenna, Advanced Laser Interferometer Gravitational-Wave Observatory, and Big Bang Observer, which can open an important window to the early Universe and the physics at some very high energy scales. © 2008 The American Physical Society URL:
