I will discuss the existence of freezing phase transitions in the settings of higher-dimensional shift spaces. I will focus on the type of potentials which would trigger a freezing phase transition where the support of the resulting ground state is an arbitrary predetermined subsystem.  To contrast this result, I give sufficient conditions on the potential which guaranty that the system never freezes.
This is based on the joint work with Jean-Rene Chazottes and Anthony Quas.
