Phase transition liquid-gas

But this is not all. In other substances, further cooling the smectic A phase results in the layers breaking up into hexagons but still sliding easily over each other this is the smectic Bhex phase. Only at even lower temperatures does the sample acquire a normal crystalline structure. Thus instead of two phase transitions gas-liquid and liquid-crystal we have found four or five transitions between different phases. 

SSB in first-order phase transitions gas-liquid and liquid-solid are within those in the thermodynamic limit repeatedly discussed earlier and in the next section. The full micromechanisms of these phase transitions are beyond the scope of this chapter what we intend to show here is that the SSB in these transitions is triggered by the same kind of degeneracies as in the JTE and PJTE [10, 67].
