the short time expansion of the propagator for a general quantum system with many degrees of freedom in a time dependent potential to orders that have not yet been accessible before Based on the earlier developed approach the propagator is expressed in terms of a discretized effective potential for which we derive and analytically solve a set of efficient recursion relations Such a discretized effective potential can be used for solving a plethora of non equilibrium many body quantum problems within the exact diagonalization arXiv 0911 5145 and arXiv 0911 5154 or Path Integral Monte Carlo approach or to set up various analytic approximation techniques to study dynamic properties of quantum systems in time dependent potentials The analytically derived results are numerically verified by treating several simple models in both imaginary and real time The following Mathematica and C codes were written for this paper Calculation of imaginary time single particle one dimensional effective action for a general time dependent potential Mathematica notebook and p 10 result Calculation of real time single particle one dimensional effective action for a general time dependent potential Mathematica notebook and p 10 result Calculation of imaginary time single particle one dimensional effective action for a forced harmonic oscillator Mathematica notebook and p 20 result Serial SPEEDUP C code for p 8 Calculation of real time single particle one dimensional effective action for a forced harmonic oscillator Mathematica notebook and p 20 result Calculation of imaginary time single particle one dimensional effective action for a time dependent harmonic oscillator Mathematica notebook and p 20 result Serial SPEEDUP C code for p 8 Calculation of real time single particle one dimensional effective action for a time dependent harmonic oscillator Mathematica notebook and p 20 result Calculation of imaginary time single particle one dimensional effective action for
