A conjecture concerning transformation of a supercooled hard sphere liquid to a metastable disordered solid.

It is conjectured that the hard sphere system has several distinct solid phases, all but one of which are metastable. The bifurcation theory analysis of freezing is extended to the description of the transition between a supercooled liquid and a disordered solid by defining a restricted phase space for the disordered solid. This approach leads to the prediction of a first order transition between a supercooled hard sphere fluid and a disordered metastable hard sphere solid. The results of the calculation are in qualitative agreement with the results of Woodcock’s molecular dynamics computer simulations. [ABSTRACT FROM AUTHOR]
