Cosmological evolution of a complex scalar field with repulsive or attractive self-interaction
Abril Suárez, Pierre-Henri Chavanis
We study the cosmological evolution of a complex scalar field with a self-interaction potential , possibly describing self-gravitating Bose-Einstein condensates, using a…
