Scale-dependent growth from a transition in dark energy dynamics

Scale-dependent growth from a transition in dark energy dynamics

We investigate the observational consequences of the quintessence field rolling to and oscillating near a minimum in its potential, if it happens close to the present epoch (z[less than or equal to]0.2). We show that in a class of models, the oscillations lead to a rapid growth of the field fluctuat...
