  Recently, ultrastable glasses have been created through vapor deposition.
Subsequently, computer simulation algorithms have been proposed that mimic the
vapor deposition process and result in simulated glasses with increased
stability. In addition, random pinning has been used to generate very stable
glassy configurations without the need for lengthy annealing or special
algorithms inspired by vapor deposition. Kinetic and mechanical stability of
experimental ultrastable glasses is compared to those of experimental glasses
formed by cooling. We provide the basis for a similar comparison for simulated
stable glasses: we analyze the kinetic and mechanical stability of simulated
glasses formed by cooling at a constant rate by examining the transformation
time to a liquid upon rapid re-heating, the inherent structure energies, and
the shear modulus. The kinetic and structural stability increases slowly with
decreasing cooling rate. The methods outlined here can be used to assess
kinetic and mechanical stability of simulated glasses generated by using
specialized algorithms.
