The subject of phase mixing/wave breaking serves as a useful paradigm to illustrate the physics of many plasma-based phenomena in the laboratory and astrophysical situations where nonlinear oscillations/waves are excited. Phase mixing leads to wave breaking and occurs whenever the characteristic frequency acquires a spatial dependence. In this paper, we review our investigations done in the area of phase mixing/wave breaking of large amplitude oscillation and waves in cold homogeneous unmagnetized plasma.
