If you have a question about this talk, please contact Tasos Avgoustidis. Scalar fields play an important role in cosmology and have attracted a great deal of recent research interests. Their impact on the large scale structure formation, especially in models with a dark-matter-scalar-field coupling, has been studied thoroughly in the linear regime. However, little is known about its behaviour in the nonlinear regime of structure formation and in the literature its effect is often approximated to be a Yukawa-type fifth force or a rescaling of gravitational constant. Here we report some recent pregress in this area, in which we solve the spatial configuration in a consistent manner, without resorting to the above approximations. This provides a new and quantitatively more accurate way for the studies in scalar field cosmology. This talk is part of the Cosmology Lunch series. This talk is included in these lists:
