Key Points

To establish the equivalence between computational quantum field theory and quantum kinetic theory for pair creation, and to analyze how field parameters influence dynamically assisted Schwinger pair production in inhomogeneous two-color electric fields.
Demonstrated analytical equivalence between computational quantum field theory and quantum kinetic theory in spatially homogeneous, time-dependent electric fields.
Numerically validated equivalence in one-dimensional time-dependent electric fields and modeled pair production under varying field frequencies, spatial widths, pulse durations, and relative phases in an inhomogeneous two-color field.
Confirmed that computational quantum field theory yields identical results to quantum kinetic theory for pair creation in one-dimensional time-dependent electric fields.
Demonstrated that pair creation enhancement is highly sensitive to field frequency and significantly amplified by narrower spatial field widths, longer pulse durations, and relative phases that maximize field strength.
