1 Motivation

Earlier simulations (Renato Lukac 1995) on Gay-Berne molecules showed:

Compression $\Longrightarrow$Demixing in a layered (smectic) structure:

 
    rho=0.40    
 
    rho=0.56
Note: at that temperature (1.25) the pure GB fluid does not exhibit a smectic phase!



Theory? $\Longrightarrow$ Entropic effect / Study using hard particles!
