Non-Gaussian work statistics at finite-time driving

We study properties of the work distribution a many-body system driven through quantum phase transition in finite time. focus on non-Gaussianity distribution, which we characterize two quantitative metrics: skewness and negentropy. In particular, Ising model show that duration ramp enhances for size system. By examining characteristics full observe there is clear intermediate regime between sudden quench adiabatic limits, where becomes increasingly skewed.
