Primes

• Phase Diagram
  • A Phase Diagram is a structured graphical representation that partitions the parameter space — typically spanned by control variables such as temperature, pressure, composition, or external field — into regions where the system exhibits qualitatively distinct phases, each characterized by a specific value or broken symmetry of the order parameter.
• Symmetry Breaking
  • Near T_c, critical phenomena exhibit universal exponents determined by the symmetry class and dimension, predicted by Landau theory
• Threshold
  • The construct is specifically a value that separates qualitatively different input-output regimes, with a non-linearity at the transition; a value that is merely prominent without delimiting regimes is not a threshold in this sense, a distinction sharpened in Landau's (1937) theory of phase transitions, which ties the regime-separating critical value to a qualitative change in an order parameter rather than to mere numerical prominence.
