Description

We study the buckling of pressurized spherical shells by 
Monte Carlo simulations in which the
detailed balance is explicitly broken -- thereby driving the shell
active, out of thermal equilibrium.
Such a shell typically has  either higher (active) or
lower (quiescent) fluctuations
compared to one in thermal equilibrium depending on how the detailed balance
is broken.
We show that, for the same set of elastic parameters, a shell
that is not buckled in thermal equilibrium can be buckled if turned
active. Similarly a shell that is buckled in thermal equilibrium
can unbuckle if turned quiescent.
Based on this result, we suggest that it is possible to experimentally design
microscopic elastic shells whose buckling can be optically controlled.
