A phase transition is a change in the nature of a phase or in the number of phases of a system as a result of a change in the external conditions. Examples: melting/freezing, vaporization/condensation, ferromagnetic transition, superconducting transition.

Relating phase transition with symmetry-breaking according to Landau Theory
I am trying to reproduce the results from this paper where they find out the expression for the Landau functional to be
$$\psi(x,t,p)=\frac{1}{4}(\frac{1}{x}+6x+px^3-4tx^2)$$
Now we plot Landau functi …

Which symmetry is broken during an AdS black hole phase transition and does it lead to chaos?
I was going through this paper in which the authors state that :
In Landau theory, a continuous phase transition is associated with a broken symmetry.
The phase transition in a black hole system can …
