Maximum absolute value of v_x as a function of time. The left panel represents the velocity evolution of the current layer system for two different cases: adiabatic medium, and non-adiabatic medium when radiative energy loss and background heating are incorporated for resistivity, η = 0.001 and plasma-β = 0.2. The right panel is for non-adiabatic evolution for different η values keeping all the other parameters the same. The vertical dashed lines represent the different phases of the evolution.
