Observational constraints on complex quintessence with attractive self-interaction

In this paper we consider that dark energy could be described solely by a complex scalar field with Bose-Einstein condensate-like potential (denoted as CSFDE), is, self-interaction and mass term. particular, analyse solution which in fast oscillation regime at late-times behaves Cosmological Constant. Our proposal adequately describes the standard homogeneous flat Fridman dynamics, furthermore, quintessence--complex scenario it is possible to mimic dynamics related energy. However, when precision cosmological tests are implemented landscape, generic Equation-of-State derived for model restricted of a_i (which corresponds scale factor turns on), cannot constrained late-time current observations, since analysis constraints parameters within values ruled out theoretical model. This result clear hint future CSFDE models with, instance, two fields order study early-time Universe.
