    "abstract": "We calculate the Wigner quasi-probability distribution for position and\nmomentum, P_W^(n)(x,p), for the energy eigenstates of the standard infinite\nwell potential, using both x- and p-space stationary-state solutions, as well\nas visualizing the results. We then evaluate the time-dependent Wigner\ndistribution, P_W(x,p;t), for Gaussian wave packet solutions of this system,\nillustrating both the short-term semi-classical time dependence, as well as\nlonger-term revival and fractional revival behavior and the structure during\nthe collapsed state. This tool provides an excellent way of demonstrating the\npatterns of highly correlated Schrodinger-cat-like `mini-packets\u0027 which appear\nat fractional multiples of the exact revival time.",
