The Mermin-Wagner theorem proved that these processes could not occur in the two dimensionalXY model, but a form of this process does occur and is named for Kosterlitz and Thouless.
The Mermin-Wagner theorem proved that these processes could not occur in the two dimensionalXY model, but a form of this process does occur and is named for Kosterlitz and Thouless. A simplemodel for these processes in rod-like polymers was introduced by Onsager. One phenomenologicaltheory of these processes expands the free energy in a power expansion as a function of a smallamplitude order paramater. In (*) liquid crystals, this process can occur between smectic A and nematic.These processes were classified based on the continuity of their derivative with respect to temperature byEhrenfest. For 10 points, name this process in which a system is transformed to a different state of matter.
