Summary: The nonlinear evolution of Langmuir oscillations in a cold plasma with ion motion and (weakly) relativistic mass variation of electrons has been studied. The results show that Langmuir mode frequency acquires spatial dependencies, leading to phase mixing and breaking at low amplitudes. The phase-mixing time is found to decrease with an increase in the electron-to-ion mass ratio parameter and relativistic factor, with ion motion inducing phase-mixing more quickly than relativistic effects.
