The Null Energy Condition Budget of a Cosmological Bounce

On a cosmological bounce background with a single minimum of the scale factor and unit duration, in units set by that duration, the quantities reported here are obtained by direct numerical evolution of the field modes from the contracting branch to the expanding branch. The violation lasts 1.507 units of cosmic time centred on the turning point. Its deepest point is -7.956e-02, reached at the centre, and its time integral is -6.126e-02. The calculation is performed on a stated model background with stated vacuum conventions, and the code and full-precision output are deposited with the paper. This study is simulated and computed from those assumptions; it is not a measurement.
