Abstract
There is a deep interconnection between the physics of flow anisotropies in relativistic heavy-ion collision experiments (RHICE) and the anisotropies observed in cosmic microwave background radiation (CMBR). This is due to the presence of superhorizon fluctuations in both cases which, for CMBR case, have origin in the inflationary phase of the universe. We discuss the basic physics of this interconnection, and present recent simulation results for the power spectrum of flow fluctuation which confirm this prediction showing exactly the same features as present in the CMBR power spectrum. These results, being useful for the study of the QGP system in RHICE, also allow us to probe some aspects of the early inverse physics under laboratory conditions, e.g.horizon entering of density fluctuations for inflation. We also show that initial strong magnetic field in RHICE can significantly enhance elliptic flow which can possibly accommodate larger \(\eta /S\) than the AdS/CFT bound.
